how would a mp3 transcode be acceptable
can someone elaborate on this subject
thanks

You first. I’ve done hundreds of hours worth. All were acceptable to me. If any contained sounds not transparent to the starting condition, I never noticed.

There was listening test by guruboolez: Short re-encoding blind listening test, wavpack - mp3 - mpc - aac - vorbis.

And there are some info in wiki: http://wiki.hydrogenaudio.org/index.php?title=Transcoding
