Comment:

 The wav container can't store opus audio, hence this error message. If you
 want to use wav, then you should use raw PCM data. If you absolutely do
 not want to loose quality, then you should simply keep the file as-is. If
 you do not want to loose quality and want to decode the data, then you can
 use
 {{{
 ./ffmpeg.exe -i /c/Users/username/Desktop/test_quality/webm.webm -c:a
 pcm_f32le /c/Users/username/Desktop/test_quality/wav-copy.wav
 }}}
 But the resulting file will be very large, larger than with your command
 line.
