Detailed Description

STATUS: work in progress WAV file input-output for (EEG)-data.

The WAV-file format allows multi-channel output. Writing the EEG-data to WAV is a convenient way for visualizing the data in an audio-visualizer software (e.g. Audacity).

For writing the WAV file, some parameters need to be passed to the WavFile struct:

Todo:

implement matrix-to-wavfile conversion
