12Recorder sound settings Player sound settings
13\par}
14
15This menu offers a selection of sound properties you may change to
16improve your sound experience.
17
18\begin{itemize}
19\item \textbf{Volume}
20
21The sound volume your music is played at. Although settable range is
220{}-100\%, many units don't produce audible output
23below 40\%. On Recorders, volume settings above 92\% will cause
24distortion (clipping) and are not recommended.
25
26\item \textbf{Bass}
27This emphasises or suppresses the lower
28(bass) sounds in the track. 0 means that bass sounds are unaltered
29(flat response).
30
31\item \textbf{Treble}
32This emphasises or suppresses the higher
33(treble) sounds in the track. 0 means that treble sounds are unaltered
34(flat response).
35
36\item \textbf{Balance}
37How much of the volume is generated by the left or right channel of the
38sound. The default, 0, means that the left and right outputs are equal
39in volume. Negative numbers increase the volume of the left channel
40relative to the right, positive numbers increase the volume of the
41right channel relative to the left.
42
43\item \textbf{Channels}
44
45This option controls the on{}-board mixing
46facilities of the Jukebox. A stereo audio signal consists of two
47channels, left and right. Available options are
48
49\begin{itemize}
50\item \textbf{Mono Left: }Plays the left channel in both stereo channels.
51\item \textbf{Mono Right:} Plays the right channel in both stereo channels.
52\item \textbf{Mono:} Mix both channels down to mono and send the mixed signal
53back to both.
54\item \textbf{Stereo:} Do not mix the signal
55\item \textbf{Stereo Narrow: }Mixes small amounts of the opposite channel into
56the left and right channels, thus making the sound seem closer
57together.
58\item \textbf{Stereo Wide:} Elements of one channel that are present in the
59opposite channel are removed from the latter. This results in the
60sound seeming further apart.
61\item \textbf{Karaoke:} Removes all sound that is the same in both channels.
62Since most vocals are recorded in this way to make the artist sound
63central, this often (but not always) has the effect of removing the
64voice track from a song.
65\end{itemize}
66
67\item \textbf{Loudness (Recorder only)}
68Loudness is an effect which emphasises bass and treble. This makes the
69track seem louder by amplifying the frequencies that the human ear
70finds hard to hear. Frequencies in the vocal range are unaffected,
71since the human ear picks these up very easily.
72
73\item \textbf{Auto Volume (Recorder only)}
74Auto volume is a feature that automatically lowers the volume on loud
75parts, and then slowly restores the volume to the previous level over a
76time interval. That time interval is configurable here. Short values
77like 20ms are useful for ensuring a constant volume for in car use and
78other applications where background noise makes a constant loudness
79desirable. A longer timeout means that the change in volume back to
80the previous level will be smoother, so there will be less sharp
81changes in volume level.
82
83\item \textbf{Super Bass (Recorder Only)}
84This setting changes the threshold at which bass frequencies are
85affected by the \textbf{Loudness} setting, making the sound of drums
86and bass guitar louder in comparison to the rest of the track. This
87setting only has an effect if \textbf{Loudness} is set to a value
88larger than 0dB.
89
90\item \textbf{MDB {}- Micronas Dynamic Bass (Recorder Only)}
91The rest of the parameters on this menu relate to the Micronas Dynamic
92Bass (MDB) function. This is designed to enable the user to hear bass
93notes that the headphones and/or speakers are not capable of
94reproducing. Every tone has a fundamental frequency (the ``main tone'') and also several harmonics, which are related to that tone. The human brain has a
95mechanism whereby it can actually infer the presence of bass notes from
96the higher harmonics that they would generate.\\
97
98The practical upshot of this is that MDB produces a more authentic
99sounding bass by tricking the brain in believing it's
100hearing tones that the headphones or speakers aren't
101capable of reproducing. Try it and see what you think.\\
102
103The MDB parameters are as follows.
104
105\begin{itemize}
106\item \textbf{MDB enable: } This turns the MDB feature on or off. For many
107users this will be the only setting they need, since Rockbox picks
108sensible defaults for the other parameters. MDB is turned off by
109default.
110\item \textbf{MDB strength:} How loud the harmonics generated by the MDB will
111be.
112\item \textbf{MDB Harmonics}: The percentage of the low notes that is
113converted into harmonics. If low notes are causing speaker distortion,
114this can be set to 100\% to eliminate the fundamental completely and
115only produce harmonics in the signal. If set to 0\% this is the same
116as turning the MDB feature off.
117\item \textbf{MDB Centre Frequency: }The cutoff frequency of your headphones or speakers. This is usually given in the specification for the headphones/speakers.
118\item \textbf{MDB shape: }It is recommended that this parameter be set to 1.5
119times the centre frequency.\\
120
121This is the frequency up to which harmonics are generated. Some of the
122lower fundamentals near the cut{}-off range
123will have their lower harmonics cut off, since they will be below the
124range of the speakers. Fundamentals between the
125cut{}-off frequency and the lower frequency will have their harmonics proportionally boosted to compensate and restore the 'loudness' of these
126notes.\\
127
128For most users, the defaults should provide an improvement in sound
129quality and can be safely left as they are. For reference, the
130defaults Rockbox uses are:

181
182\subsubsection{\label{ref:PlaybackOptions}Playback Options}
183This menu is for configuring settings related to MP3 playback
184
185\begin{itemize}
186\item \textbf{Shuffle}
187Select shuffle ON/OFF. This alters how Rockbox will select which next
188song to play.
189\item \textbf{Repeat}
190Repeat modes are Off/One/All. ``Off'' means no
191repeat. ``One'' means repeat one track over
192and over. ``All'' means repeat playlist/directory.
193\item \item{Play Selected First }
194This setting controls what happens when you press PLAY on a file in a
195directory and shuffle mode is on. If this setting is Yes, the file you
196selected will be played first. If this setting is No, a random file in
197the directory will be played first.
198\item \textbf{Resume}
199Sets whether Rockbox will resume playing at the point where you shut
200off. Options are: Ask/Yes/No/Ask once.
201``Ask'' means it will ask at boot time. ``Yes'' means it will unconditionally try to resume. ``No'' means it will not resume. ``Ask once'' will erase the resume info if you answer no, and thus not ask you again.
202\item \textbf{FFwd / Rewind}
203Two options are available at this point
204
205\begin{itemize}
206\item \textbf{FF/RW Min Step}
207The smallest step, in seconds, you want to fast forward or rewind in a
208track.
209\item \textbf{FF/RW Accel}
210How fast you want search (ffwd/rew) to accelerate when you hold
211down the button. ``Off'' means no acceleration. ``2x/1s'' means double the
212search speed once every second the button is held. ``2x/5s'' means double the search speed once every 5 seconds the button is held.
213\end{itemize}
214
215\item \textbf{Anti{}-skip Buffer}
216This setting is really ``extra anti{}-skip''. It lets you set
217a timer for how many seconds earlier than normally necessary the disk
218should spin up and start reading data. You don't need
219this unless you shake and bump the unit a lot. Spinning up the disk
220earlier than necessary naturally drains the batteries a little extra.
221Most users will not need this setting.
222
223\item \textbf{Fade on Stop/Pause}
224This setting enables and disables a fade effect when you pause
225or stop playing a song. Fade is a progressive increase or reduction of
226volume, from your set volume to 0, and vice versa.
227
228\item \textbf{ID3 tag priority}
229ID3 tags in an MP3 file contain information about the artist, title,
230album etc. of the track. This option controls whether Rockbox uses the information from ID3v2 tags in preference to that from ID3v1 tags when both types of tag are present.
231\end{itemize}
232
233\subsection{File View}
234This menu deals with options relating to how the file browser displays
235files
236
237\begin{itemize}
238\item \textbf{Sort Case Sensitive}
239If this option is enabled files that start with a
240lower case letter will appear after the files that start with an upper case letter have all been listed If disabled, then case will be ignored when sorting files.
241\item \textbf{Sort Directories}
242This option controls how Rockbox sorts folders. The default is to sort
243them alphabetically. ``By date'' sorts them with the oldest folder
244first. ``By newest date'' sorts them with the newest folder first.
245
246\item \textbf{Sort Files}
247This option controls how Rockbox sorts files. In addition to the
248options for directory sorting above, there is a ``By type'' option
249which sorts files alphabetically by their type (such as .mp3) then
250alphabetically within each type.
251
252\item \textbf{\label{ref:ShowFiles}Show Files}
253Controls which files are displayed in the directory browser:
254
255\begin{itemize}
256\item \textbf{Music: }
257Only directories, .mp3, .mp2, .mpa and .m3u files
258are shown. Extensions are strippe'd. Files anddirectories starting with . Or with the ``hidden'' flag set are hidden.
259\item \textbf{Playlists:}
260Only shows directories and playlists, for
261simplified navigation.
262\item \textbf{Supported:}
263All directories and files Rockbox understands (see page \pageref{ref:Supportedfileformats}) are shown. Files and directories starting with . or with the
264``hidden'' flag set are hidden.
265\item \textbf{All:}
266All files and directories are shown. Extensions are shown. No files or
267directories arehidden
268\end{itemize}
269
270\item \textbf{Follow Playlist}
271If Follow Playlist is set to ``Yes'', you will find yourself in the same
272directory as the currently playing file if you go to the Directory
273Browser from the WPS. If set to ``No'', you will stay in the same directory as you were last in.
274
275\item \textbf{Show Icons}
276This indicates whether Rockbox will display an icon representing what
277type a file is on the left of the file in the browser. For details of
278these icons, please see page \pageref{ref:Supportedfileformats}.
279\end{itemize}
280
281\subsection{\label{ref:Displayoptions}Display Options}
282
283\begin{itemize}
284\item \textbf{Browse fonts}
285Browse the fonts that reside in your \textbf{/.rockbox} directory.
286Selecting one will activate it. See page \pageref{ref:Loadingfonts} for further details about fonts.
287
288\item \textbf{Browse WPS files}
289Opens the file browser in the \textbf{/.rockbox} directory and displays
290all .wps files. Selecting one will activate it, stop will exit back to
291the menu.\\
292
293For further information about the WPS see page \pageref{ref:WPS}. For
294information about editing a .wps file see page \pageref{ref:ConfiguringtheWPS}.
295
296\item \textbf{LCD Settings}
297
298%\begin{itemize}
299This submenu contains settings that relate to the display of the
300Jukebox.
301\item \textbf{Backlight:}
302How long the backlight shines after a key
303press. Set to OFF to never light it, set to ON to never shut it off or
304set a preferred timeout period.
305\item \textbf{Backlight on WhenPlugged:}
306This option turns the backlight on constantly while the charger cable is connected.
307\item \textbf{Caption Backlight:} This option turns the backlight on for
30825 seconds either side of the start of a new track so that the display
309can be read to see song information.
310\item \textbf{Contrast:} Changes the contrast of your LCD display.
311Warning: Setting the contrast too dark or too light can make it hard to
312find this menu option again!
313\item \textbf{LCD Mode} (Recorder only): This setting lets you invert
314the whole screen, so now you get a black background and green text
315graphics.
316\item \textbf{Upside Down: }Displays the screen so that the top of the
317display is nearest the buttons. This is sometimes useful when carrying
318the Recorder in a pocket for easy access to the headphone socket.
319\item \textbf{Line Selector: }Select this option to have a bar of
320inverted text (``Bar'' option) mark the current line in the File
321Browser rather than the default arrow to the left (``Pointer'' option).
322 This gives slightly more room for filenames.
323%\end{itemize}
324
325\item \textbf{Scrolling}
326This feature controls how text will scroll in Rockbox. You can configure
327the following parameters:
328
329\begin{itemize}
330\item \textbf{Scroll Speed:}
331Controls how many times per second the scrolling text moves a step.
332\item \textbf{Scroll StartDelay:}
333Controls how many milliseconds Rockbox should wait before a new text begins scrolling.
334\item \textbf{Scroll Step Size:}
335Controls how many pixels the text scroll should move for each step. (Recorder/Ondio only)
336\item \textbf{Bidirectional Scroll Limit: }
337Rockbox has two different scroll methods, always scrolling the text to the left, and when the line has ended, beginning again at the start, or moving to the
338left until you can read the end of the line, and scroll right until you
339see the beginning again. Rockbox chooses which method it should use,
340depending of how much it has to scroll left. This setting lets you tell
341Rockbox where that limit is, expressed in percentage of line length.
342\end{itemize}
343
344\item \textbf{Status/Scrollbar (Recorder only)}
345Settings related to on screen status display and the scrollbar.
346
347\begin{itemize}
348\item \textbf{Scroll Bar: }Enables or disables the scroll bar at the
349left.
350\item \textbf{Status Bar: }Enables or disables the status bar
351at the upper side.
352\item \textbf{Button Bar:} Enables or disables the button bar prompts
353for the F keys at the bottom of the screen.
354\item \textbf{Volume Display:} Controls whether the volume is displayed
355as a graphic or a numerical percentage value on the Status Bar.
356\item \textbf{Battery Display: }Controls whether the battery charge
357status is displayed as a graphic or numerical percentage value on the
358Status Bar.
359\end{itemize}
360
361\item \textbf{Peak Meter (Recorder only) }
362The peak meter can be configured with a number of parameters. (For a description of the peak meter see page \pageref{ref:Peakmeter}.)
363
364\begin{itemize}
365\item \textbf{Peak Release:}
366This determines how fast the bar shrinks when the music becomes softer.
367Lower values make the peak meter look smoother.
368\item \textbf{Peak Hold Time:}
369Specifies the time after which the peak indicator will reset. If you set this value e.g. to 5s then the peak indicator displays the loudest volume value
370that occurred within the last 5 seconds. Big values are good if you
371want to find the peak level of a song, which might be of interest when
372copying music from the jukebox via the analogue output to some other
373recording device.
374\item \textbf{Clip Hold Time:}
375How long the clipping indicator will be visible after clipping was detected
376\item \textbf{Performance:}
377In high performance mode, the peak meter is updated as often as possible. This reduces the chance of missing a peak value, making the peak meter more precise. In energy save mode the peak meter is updated just often enough to look fluid.
378This reduces the load on the CPU and thus saves a little bit of energy. If you crave every second of runtime for your jukebox or simply use the peak meter as a screen effect, the use of energy save mode is recommended. If you want to use
379the peak meter as a measuring instrument you'll want to use high performance mode.
380\item \textbf{Scale:}
381Select whether the peak meter displays linear or logarithmic values. In
382``dB'' (decibel) scale the volume values are scaled logarithmically.
383This very similar to the perception of loudness. The volume meters of
384digital audio devices usually are scaled this way. If you are
385interested in the power level that is applied to your headphones you
386should choose ``linear'' display. Unfortunately this value
387doesn't have real units like volts or watts since that
388depends on the phones. So they can only be displayed as percentage
389values.
390\item \textbf{Minimum and maximum range:} These two options define the
391full value range that the peak meter displays. Recommended values for
392dbFs are {}-40 for min. and 0 for maximum. For linear display, use 0
393and 100\%. Note that {}-40 dbFs is approximately 1\% in linear value,
394but if you change the minimum setting in linear mode slightly and then change to dbFs there will be a large change. You can use these values for
395'zooming' into the peak meter.
396\end{itemize}
397\end{itemize}
398
399\subsubsection{\label{ref:SystemOptions}System Options}
400
401\begin{itemize}
402\item \textbf{Battery}
403Options relating to the batteries in the Jukebox unit.
404\begin{itemize}
405\item \textbf{Battery Capacity} can be used to tell the Jukebox what
406capacity (in mAh) of battery is being used inside it. The default is
4071500mAh for NiMH battery based units, and 2300mAh for LiOn battery
408based units, which is the capacity value for the standard batteries
409shipped with these units. This value is used for calculating remaining
410battery life.
411\item \textbf{Deep discharge (Non{}-FM recorder only)}
412Set this to ON if you intend to keep your charger connected for a long
413period of time. It lets the batteries go down to 10\% before starting
414to charge again. Setting this to OFF will cause the charging to restart
415on 95\%.
416\item \textbf{Trickle Charge (Non{}-FM recorder only)}
417The Jukebox cannot be turned off while the charger is connected.
418Therefore, trickle charge is needed to keep the batteries full after
419charging has completed. For more in depth information about charging
420see Battery FAQ in your \textbf{/.rockbox/docs }directory.
421\end{itemize}
422
423\item \textbf{Disk}
424Options relating to the hard disk.
425
426\begin{itemize}
427\item \textbf{DiskSpindown:}
428Rockbox has a timer that makes it spin down the hard disk after being idle for acertain time. You can modify this timeout here. This idle time is only
429affected by user activity, like navigating through file browser. When
430the hard disk spins up to fill mp3 buffer, it automatically spins down
431afterwards.
432\item \textbf{Disk Poweroff:}(non v2/FM{}-recorder only)
433Whether the disk is powered OFF or only set to ``sleep'' when spun
434down. Power off uses less power but takes longer to spin{}-up.
435\end{itemize}
436
437\item \textbf{Time and Date (Recorder Only)}
438Time related menu options.
439
440\begin{itemize}
441\item \textbf{Set Time/Date: }
442Set current time and date.
443\item \textbf{Time Format: }
444Choose 12 or 24 Hour clock.
445\end{itemize}
446
447\item \textbf{\label{ref:idlepoweroff}Idle Poweroff}
448Rockbox can be configured to turn off power after the unit has been idle
449for a defined number of minutes. The unit is idle when playback is
450stopped or paused. It is not idle while the USB or charger is
451connected, or while recording.
452
453\item \textbf{Sleep Timer}
454This option lets you power off your jukebox after playing for a given
455time. This setting is reset on boot. Using this option disables the
456\textbf{Wake up alarm} (see below).
457
458\item \textbf{Wake up alarm (Recorder v2/FM only)}
459This option turns the Jukebox off and then starts it up again at the
460specified time. This is most useful when combined with the Resume
461setting in the Playback options set to ``Yes'', so that the Jukebox
462wakes up and immediately starts playing music. Use LEFT and RIGHT to
463adjust the minutes setting, UP and DOWN to adjust the HOURS. PLAY
464confirms the alarm and shuts your Jukebox down, and STOP cancels
465setting an alarm. If the Jukebox is turned on again before the alarm
466occurs the alarm will be canceled. Using this option disables the \textbf{Sleep Timer} (see above).
467
468\item \textbf{Limits}
469This submenu relates to limits in the Rockbox operating system.
470
471\begin{itemize}
472\item \textbf{Max files in dir browser: }Configurable limit of files in
473the directory browser (file buffer size). You can configure the size to
474be between 50 and 10000 files in steps of 50 files. The default is 400,
475higher values will shorten the music buffer.\\
476
477Note: the device must be rebooted for settings to take effect!
478\item \textbf{Max playlist size: }Option to configure the maximum size
479of a playlist. The playlist size can be between 1000 and 20000 files in
480steps of 1000. By default it is 10000. Higher values will shorten the
481music buffer.\\
482
483Note: the device must be rebooted for settings to take effect!
484\end{itemize}
485
486\item \textbf{Car Adapter Mode}
487This option turns on and off the car ignition auto stop
488function.
489
490When using the Jukebox in a car, car adapter mode automatically stops
491playback on the Jukebox when power (i.e. from cigarette lighter power
492adapter) to the external DC in jack is turned off.
493
494When the external power off condition is detected, the Car Adapter Mode
495function only pauses the playback. In order to shut down the Jukebox
496completely the \textbf{Idle Poweroff} function (see above) must also be
497set.
498
499If power to the DC in jack is turned back on before the \textbf{Idle
500Poweroff} function has shut the Jukebox off, playback will be resumed
5015 seconds after the power is applied. This delay is to allow for the
502time while the car engine is being started. Once the Jukebox is shut
503off either manually, or automatically with the \textbf{Idle Poweroff
504}function, it must be powered up manually to resume playback.
505
506\item \textbf{Line In (Player only)}
507This option activates the line in port on Jukebox Player, which
508is off by default.
509
510This is useful for such applications as:
511\begin{itemize}
512\item Game boy {}-{\textgreater} Jukebox {}-{\textgreater} human
513\item laptop {}-{\textgreater} Jukebox {}-{\textgreater}human
514\item LAN party computer {}-{\textgreater} Jukebox {}-{\textgreater} human
515\end{itemize}
516
517\item \textbf{Manage settings}
518This submenu deals with loading and saving settings.
519
520\begin{itemize}
521\item \textbf{Browse .cfg Files: }
522This displays a list of configuration
523(.cfg) files stored in the \textbf{/.rockbox} system directory. This
524is useful if the Jukebox is plugged into more than one different output
525device (e.g. headphones, computer, car stereo, hi{}-fi) so that a settings file can be maintained for each.
526\item \textbf{Browse Firmwares:} This displays a list of firmware (.mod
527for Players and .ajz for Recorders) file in the \textbf{/.rockbox} system directory. Playing a firmware file loads it into memory. Thus it is possible to
528run the original Archos firmware or a different version of Rockbox from
529here assuming that you have the right files installed on your disk.
530\item \textbf{Reset Settings: }This wipes the saved settings in the
531Jukebox and resets all settings to their default values.
532\item \textbf{Write .cfg file: }Saves the current settings into a .cfg
533file for later use with \textbf{Browse .cfg Files} above.
534\end{itemize}

538\subsubsection{\label{ref:Bookmarkconfigactual}Bookmarking}
539
540\begin{itemize}
541\item \textbf{Bookmark on Stop}
542Write a bookmark to the disk whenever the stop key is pressed. If
543playback is stopped it can be resumed easily at a later time. The
544\textbf{Resume} function remembers your position in the most
545recently accessed track regardless of this setting.
546\item \textbf{Load Last Bookmark}
547When this is on, Rockbox automatically returns to the position of the
548last bookmark within a file when it is played. If set to Ask, Rockbox
549will ask the user whether they want to start from the beginning or the
550bookmark. When set to no, playback always starts from the beginning
551and the Bookmark file must be played or \textbf{Load Bookmark} selected
552from the \textbf{Bookmarks} submenu of the Main Menu while the file is
553playing.
554\item \textbf{Maintain a list of Recently Used Bookmarks}
555If this option is turned on, Rockbox will store a list of Bookmarks that
556have been accessed recently. This is then accessible from the
557\textbf{Recent Bookmarks} option of the \textbf{Bookmarks} submenu of
558the Main Menu.
559\end{itemize}
560
561\subsection{\label{ref:Language}Language}
562This setting controls the language of the Rockbox user interface.
563Selecting a language will activate it. The language files must be in
564the \textbf{/.rockbox/lang/} directory.
565
566See page \pageref{ref:Loadinglanguages} for further details about
567languages.
568
569\subsection{Voice}
570
571\begin{itemize}
572\item \textbf{Voice Menus}
573This option turns on the Voice User Interface, which will read out menu items and settings as they are selected by the cursor. In order for this to work, a voice file must be present in the \textbf{/.rockbox/lang/} directory on the recorder. Voice files are large (1.5MB) and are not shipped with Rockbox by
574default.
575
576The voice file is the name of the language for which it is made,
577followed by the extension .voice. So for English, the file name would
578be \textbf{english.voice}.
579
580This option is on by default. It will do nothing unless the appropriate
581.voice file is installed in the correct place on the Jukebox.
582
583\begin{itemize}
584\item \textbf{Limitations}
585\begin{itemize}
586\item Setting the Sound Option \textbf{Channels} to ``karaoke'' may
587disable voice menus.
588\item Plugins and the wake up alarm do not support voice features.
589\end{itemize}
590
591\item \textbf{Voice Directories}
592This option turns on the speaking of directory names. The Jukebox is
593not powerful enough to produce these voices in real time, so a number of options are available.
594
595\begin{itemize}
596\item \textbf{.talk mp3 clip: }
597Use special pre{}-recorded MP3 files (\textbf{\_dirname.talk}) in each directory. These must be generated in advance, and are typically produced synthetically using a text to speech engine on a PC. If no such file exists, the output is as for the ``numbers'' option below.
598\item \textbf{Spell: }
599Speak the directory name by spelling it out letter
600by letter. Support is provided only for the most common letters and
601punctuation.
602\item \textbf{Numbers: }
603Each directory is assigned a number based upon its position in the file list. They are then announced as ``Directory 1'', ``Directory 2'' etc.
604\item \textbf{Off: }
605No attempt will be made to speak directory names.
606\end{itemize}
607
608\item \textbf{Voice Filenames}
609This option turns on the speaking of directory names. The options
610provided are ``Spell'', ``Numbers'', and ``Off'' which function the same as for \textbf{Voice Directories} and ``.talk mp3 clip'', which functions as above except that the files are named with the same name as the music file (e.g. \textbf{Punkadiddle.mp3 } would require a file called \textbf{Punkadiddle.mp3.talk}).
