The splitter buffer length.
BASS_SetConfig( BASS_CONFIG_SPLIT_BUFFER, DWORD length );
|length||The buffer length in milliseconds.|
The buffer will always be kept as empty as possible, so its size does not necessarily affect latency; it just determines how far splitter streams can drift apart before there are buffer overflow issues for those left behind.
Changes do not affect buffers that have already been allocated; any sources that have already had splitter streams created will continue to use their existing buffers.
