The global sample volume level.
BASS_SetConfig( BASS_CONFIG_GVOL_SAMPLE, DWORD volume );
volume | Sample global volume level... 0 (silent) to 10000 (full). |
A channel's final volume = channel volume x global volume / 10000. For example, if a stream's volume is 0.5 and the global stream volume is 8000, then effectively the stream's volume level is 0.4 (0.5 x 8000 / 10000 = 0.4).
