Sets up a user DSP function on a stream, MOD music, or recording channel.
HDSP BASS_ChannelSetDSP( DWORD handle, DSPPROC *proc, void *user, int priority );
|handle||The channel handle... a HSTREAM, HMUSIC, or HRECORD.|
|proc||The callback function.|
|user||User instance data to pass to the callback function.|
|priority||The priority of the new DSP, which determines its position in the DSP chain. DSPs with higher priority are called before those with lower.|
|BASS_ERROR_HANDLE||handle is not a valid channel.|
Multiple DSP functions may be used per channel, in which case the order that the functions are called is determined by their priorities. Any DSPs that have the same priority are called in the order that they were added.
DSP functions can be applied to MOD musics and streams, but not samples. If you want to apply a DSP function to a sample, then you should stream the sample.
