I have been using the linux command line utility 'mac' which I installed from www.rarewares.org. Previously, I have used the graphical Windows utility under wine. I have converted all my ape's to flac, which was a truly free format from the beginning and is much better supported on different platforms than Monkey's audio. The MP3 format is a lossy format, which means audio quality is sacrificed in order to keep the relatively small size of the files. Pretty much every site will tell you that you should never convert a lossless format audio file to MP3 format unless you are OK with losing some audio quality. best .ape to mp3 converter item look what i found convert ape to mp3 online The registry key of ape2mp3.exe is invalid or damaged.
