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.
