Remarks

This function operates in the same way as BASS_ChannelGetLevel(Int32) but has greater flexibility on how the level is measured. The levels are not clipped, so may exceed +/-1.0 on floating-point channels.

BASS_ERROR_HANDLEhandle is not a valid channel.
BASS_ERROR_NOPLAYThe channel is not playing.
BASS_ERROR_ENDEDThe decoding channel has reached the end.
BASS_ERROR_BUFLOSTShould not happen... check that a valid window handle was used with BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr).
