 The last 8 channels come out as if they used the wrong IR channels. This
 code works correctly (same input files) with ffmpeg git-2019-10-19 however
 that version has a 16th missing channel bug for audio file format .wv,
 which is fixed in later ffmpeg versions. So I can't use the older ffmpeg
 with audio files larger than 4gb (unless you can point me to another audio
 output file format that supports >4GB files and 16 channels).
