Hey, i'm looking for a way to convert my MP4 files into MP3 with no loss of quality on the audio, because the current one i am using has a noticable drop in audio quality
Free Studio You can do many things with it. You can convert your music too. EDIT: or you can just get the audio converter.
Use format factory. It converts to virtually most media types. Except dpg videos used for the DS. But I don't have one anymore, so I convert videos for my PSP instead.
I use SUPER by erightsoft.com to convert video files to PSP format, but it looks like it can also convert different audio files as well. Now, whether the quality is affected or not, I don't know. It probably will go down a bit though - it does for my video files, never did use it on audio files before . . .
