The goal of this PR is to add implementation of compand effect. Let me rephrase SoX documentation to explain parameters:
The transfer function (soft_knee:threshold,...') says that very soft sounds (below thresholddB) will remain unchanged. This will stop the compander from boosting the volume on 'silent' passages such as between movements. However, sounds in the range db_fromdB to 0dB (maximum volume) will be boosted so that the db_fromdB dynamic range of the original music will be compressed into a db_todB range
The default parameters are actually transparent for audio files, meaning the command not change the audio.
