Cannot be used for testing Opus encoded files？ #103

hpuzz commented 7 months ago

I want to test the MOS score of the OPUS file, but it seems that the code can only read the WAV file format.Is there any way to solve this problem？

OPUS encoder is a thing on it's own. Means it hold all the info about stream, error correction, etc inside the stream. And using different encoding approaches than WAV. So, short answer - no, this problem cannot be solved directly with OPUS, but you can transcode into WAV and test.
