Does converting audio files reduce quality?

The short answer to your question is that, at 320 kbps, with either MP3 or AAC, music sounds almost as good as it does at CD quality. In fact, it sounds so close that many people insist they cannot hear the difference at all – and it only takes up between 20\% and 25\% of the space or bandwidth.

Does converting MP3 to M4A lose quality?

No. Once lossy formats are encoded, any data not saved within the file is lost. You could convert a lossy MP3 to a WAV or an M4A file but the quality of the WAV or M4A would be exactly the same as the original MP3.

What is the best lossy format for audio files?

Our pick for the best lossy format when it comes to MP3’s and AAC’s is the MP3. This is surprising considering that the AAC is often thought of as the better format.
