consistency among multiple channel audio files, is to define the order in which the channels are laid out in the audio file. Several external standards define parts of the following master channel layout: 1. Front Left - FL 2. Front Right - FR 3. Front Center - FC 4. Low Frequency - LF 5. Back Left - BL 6. Back Right - BR 7. Front Left of Center - FLC 8.

This class actually has uses beyond supporting soundcards with more than 2 outputs. You could use it to swap left and right channels in a stereo signal, or provide a simple switch that selects between several mono inputs. You also don’t need to output to the soundcard. The WaveFileReader will happily write multi-channel WAV files. However, there are no guarantees …
WAV - Wikipedia

Since the sampling rate of a WAV file can vary from 1 Hz to 4.3 GHz, and the number of channels can be as high as 65535, .wav files have also been used for non-audio data. LTspice , for instance, can store multiple circuit trace waveforms in separate channels, at any appropriate sampling rate, with the full-scale range representing ±1 V or A ...

With Windows 2000, Microsoft introduced a WAVE_FORMAT_EXTENSIBLE header which specifies multiple audio channel data (surround sound) along with speaker positions. This enhancement provided for custom extensions to the format chunk. Ambiguity relating to sample types and container sizes in the standard WAV format was also addressed.
