BASS_CONFIG_FLOATDSP config option
Pass 32-bit floating-point sample data to all DSP functions?
BASS_SetConfig(
BASS_CONFIG_FLOATDSP,
BOOL floatdsp
);
Parameters
| floatdsp | If TRUE, 32-bit floating-point sample data is passed to all DSPPROC callback functions. |
Remarks
Normally DSP functions receive sample data in whatever format the channel is using, ie. it can be 8, 16 or 32-bit. But using this config option, BASS will convert 8/16-bit sample data to 32-bit floating-point before passing it to DSP functions, and then convert it back after all the DSP functions are done. As well as simplifying the DSP code (no need for 8/16-bit processing), this also means that there is no degradation of quality as sample data passes through a chain of DSP.This config option also applies to effects set via BASS_ChannelSetFX, except for DX8 effects when using the "With FX flag" DX8 effect implementation.
Changing the setting while there are DSP or FX set could cause problems, so should be avoided.
