18 | is lowered, recordings are compressed more (meaning worse sound quality), | ||

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 | ||

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. | ||

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: | ||
