Assembly: Bass.Net (in Bass.Net.dll) Version: 18.104.22.168
Property ValueType: Int32
As the InputChannel is a dummy custom decoding stream you can not call BASS_ChannelGetData(Int32, IntPtr, Int32) directly on it in order to directly get the sample data; nor can you use it directly as a source stream for any (mixer)output! Instead use a DSPPROC via BASS_ChannelSetDSP(Int32, DSPPROC, IntPtr, Int32) to retrieve the sample data.
Note: However, you might independently set any DSP/FX on the full-duplex output using the OutputChannel instead.
