/*
|

Attenuation range in centibels.
|
||||
Attenuation range is the dynamic range of the volume envelope generator
|
||||
from 0 to the end of attack segment.
|
||||
fluidsynth is a 24 bit synth, it could (should??) be 144 dB of attenuation.
|
||||
However the spec makes no distinction between 16 or 24 bit synths, so use
|
||||
96 dB here.
|
||||
|
||||
Note about usefulness of 24 bits:
|
||||
1)Even fluidsynth is a 24 bit synth, this format is only relevant if
|
||||
the sample format coming from the soundfont is 24 bits and the audio sample format
|
||||
choosen by the application (audio.sample.format) is not 16 bits.
|
||||
|
||||
2)When the sample soundfont is 16 bits, the internal 24 bits number have
|
||||
16 bits msb and lsb to 0. Consequently, at the DAC output, the dynamic range of
|
||||
this 24 bit sample is reduced to the the dynamic of a 16 bits sample (ie 90 db)
|
||||
even if this sample is produced by the audio driver using an audio sample format
|
||||
compatible for a 24 bit DAC.
|
||||
|
||||
3)When the audio sample format settings is 16 bits (audio.sample.format), the
|
||||
audio driver will make use of a 16 bit DAC, and the dynamic will be reduced to 96 dB
|
||||
even if the initial sample comes from a 24 bits soundfont.
|
||||
|
||||
In both cases (2) or (3), the real dynamic range is only 96 dB.
|
||||
|
||||
Other consideration for FLUID_NOISE_FLOOR related to case (1),(2,3):
|
||||
- for case (1), FLUID_NOISE_FLOOR should be the noise floor for 24 bits (i.e -138 dB).
|
||||
- for case (2) or (3), FLUID_NOISE_FLOOR should be the noise floor for 16 bits (i.e -90 dB).
