- \section{Loudness}
- When listening at low volumes, the ear will tend to make bass and treble
- frequencies sound quieter than they really are. To compensate for this,
- \setting{Loudness} is an effect which emphasises bass and treble in a fashion
- suited to the human ear. Frequencies in the vocal range are unaffected, since
- the human ear picks these up very easily at any sound level.
- It is of course also possible to use this effect at higher volumes for
- enhanced bass and treble.
-\section{Auto Volume}
- Auto volume is a feature that automatically lowers the volume on loud parts,
- and then slowly restores the volume to the previous level over a time
- interval. This setting allows this time interval to be configured. Short
- values like 20~ms are useful for ensuring a constant volume for in-car use and
- other applications where background noise makes a constant loudness desirable.
- A longer timeout means that the change in volume back to the previous level
- will be smoother, so there will be fewer sharp changes in volume level.
-\section{Super Bass}
- This setting changes the threshold at which bass frequencies are affected by
- the \setting{Loudness} setting, making the sound of drums and bass guitar
- louder in comparison to the rest of the sound. This setting only has an
- effect if \setting{Loudness} is set to a value larger than 0~dB.
-\section{MDB {}-- Micronas Dynamic Bass}
- The rest of the parameters in this menu relate to the Micronas Dynamic
- Bass (MDB) function. MDB is designed to enable the user to hear bass
- notes that the headphones and/or speakers are not capable of reproducing.
- Every tone has a fundamental frequency (the ``main tone'') and also several
- harmonics, which are related to that tone. The human brain has a mechanism
- whereby it can actually infer the presence of bass notes from the higher
- harmonics that they would generate.
- The practical upshot of this is that MDB produces a more authentic sounding
- bass by tricking the brain into believing it is hearing tones that the
- headphones or speakers are not capable of reproducing.
- The MDB parameters are as follows:
- %
- \begin{description}
- \item[MDB enable.]
- This turns the MDB feature on or off. For many users this will be the
- only setting they need, since Rockbox picks sensible defaults for the
- other parameters. MDB is turned off by default.
- \item[MDB strength.]
- How loud the harmonics generated by MDB will be.
- \item[MDB Harmonics.]
- The percentage of the low notes that is converted into harmonics.
- If low notes are causing speaker distortion, this can be set to 100\%
- to eliminate the fundamental completely and only produce harmonics in the
- signal. If set to 0\% this is the same as turning the MDB feature off.
- \item[MDB Centre Frequency.]
- The cutoff frequency of your headphones or speakers. This is usually
- given in the specification for the headphones/speakers.
- \item[MDB shape.]
- It is recommended that this parameter be set to 1.5 times the centre frequency.
- This is the frequency up to which harmonics are generated. Some of the
- lower fundamentals near the cut{}-off range will have their lower
- harmonics cut, since they will be below the range of the speakers.
- Fundamentals between the cut{}-off frequency and the lower frequency
- will have their harmonics proportionally boosted to compensate and restore
- the `loudness' of these notes.
- For most users, the defaults should provide an improvement in sound
- quality and can be safely left as they are. For reference, the defaults
- Rockbox uses are:
