цитата (Why is lossy transcoding bad?
Whenever you encode a file to a lossy format (such as mp3, m4a(AAC), ogg, or mpc) information is permanently lost. It doesn't matter what you do, it's impossible to get this information back without making a new rip from the original lossless source. If you re-encode it to a different format or bitrate, you are reducing the quality. This applies to any lossy to lossy conversion, so even if you convert from 320kbps to 192kbps, the final file will still sound worse than if you had just ripped to 192kbps in the first place.
It's also important to remember to verify that lossless rips actually came from an original source. People that download lossless expect it to be identical to the original. There's no point in people downloading a bigger file just to get another lossy rip.)
Поэтому lossy to lossy недопустимы, отсюда и несколько ошибок в последнем вопросе, а в первом всё правильно
