205 \section{Loudness}
206 When listening at low volumes, the ear will tend to make bass and treble
207 frequencies sound quieter than they really are. To compensate for this,
208 \setting{Loudness} is an effect which emphasises bass and treble in a fashion
209 suited to the human ear. Frequencies in the vocal range are unaffected, since
210 the human ear picks these up very easily at any sound level.
211 It is of course also possible to use this effect at higher volumes for
212 enhanced bass and treble.

216\section{Auto Volume}
217 Auto volume is a feature that automatically lowers the volume on loud parts,
218 and then slowly restores the volume to the previous level over a time
219 interval. This setting allows this time interval to be configured. Short
220 values like 20~ms are useful for ensuring a constant volume for in-car use and
221 other applications where background noise makes a constant loudness desirable.
222 A longer timeout means that the change in volume back to the previous level
223 will be smoother, so there will be fewer sharp changes in volume level.

227\section{Super Bass}
228 This setting changes the threshold at which bass frequencies are affected by
229 the \setting{Loudness} setting, making the sound of drums and bass guitar
230 louder in comparison to the rest of the sound. This setting only has an
231 effect if \setting{Loudness} is set to a value larger than 0~dB.

235\section{MDB {}-- Micronas Dynamic Bass}
236 The rest of the parameters in this menu relate to the Micronas Dynamic
237 Bass (MDB) function. MDB is designed to enable the user to hear bass
238 notes that the headphones and/or speakers are not capable of reproducing.
239 Every tone has a fundamental frequency (the ``main tone'') and also several
240 harmonics, which are related to that tone. The human brain has a mechanism
241 whereby it can actually infer the presence of bass notes from the higher
242 harmonics that they would generate.
243
244 The practical upshot of this is that MDB produces a more authentic sounding
245 bass by tricking the brain into believing it is hearing tones that the
246 headphones or speakers are not capable of reproducing.
247
248 The MDB parameters are as follows:
249 %
250 \begin{description}
251 \item[MDB enable.]
252 This turns the MDB feature on or off. For many users this will be the
253 only setting they need, since Rockbox picks sensible defaults for the
254 other parameters. MDB is turned off by default.
255 \item[MDB strength.]
256 How loud the harmonics generated by MDB will be.
257 \item[MDB Harmonics.]
258 The percentage of the low notes that is converted into harmonics.
259 If low notes are causing speaker distortion, this can be set to 100\%
260 to eliminate the fundamental completely and only produce harmonics in the
261 signal. If set to 0\% this is the same as turning the MDB feature off.
262 \item[MDB Centre Frequency.]
263 The cutoff frequency of your headphones or speakers. This is usually
264 given in the specification for the headphones/speakers.
265 \item[MDB shape.]
266 It is recommended that this parameter be set to 1.5 times the centre frequency.
267
268 This is the frequency up to which harmonics are generated. Some of the
269 lower fundamentals near the cut{}-off range will have their lower
270 harmonics cut, since they will be below the range of the speakers.
271 Fundamentals between the cut{}-off frequency and the lower frequency
272 will have their harmonics proportionally boosted to compensate and restore
273 the `loudness' of these notes.
274
275 For most users, the defaults should provide an improvement in sound
276 quality and can be safely left as they are. For reference, the defaults
277 Rockbox uses are:
