Hello


i got some M4A audio files that i would convert in MP3's. Now my question is:


Is a M4A file with 256kbps the equivalent to a MP3 File with 320kbps. if it is so, can i convert the M4A File to a MP3 with a constant bitrate of 320 kbps? or should i convert it to the same bitrate of 256kbps??






thanks for answers rolleyes.gif rolleyes.gif rolleyes.gif

If the M4A is AAC (which at 256Kbps it is) it's already compressed with a lossy codec. Transcoding to mp3 will further degrade quality.

If you need the audio as mp3 then it's best to seek out the lossless source material and transcode from that.

IMO, transcoding lossy to lossy is bad form, as if/when those files make their way into the wild it pollutes the world with substandard quality files.
