Thanks in advance

The problem with those options like you said are finding programs that work with the various formats. WMM only likes mp3 and wave files...well at least mine is like that. And Matroska files only play back on my VLC player or GOM player. I sure I could spend the time/cash to find a program to do all that but I would probably need a new computer to make it worth getting it lol...Mosc wrote:Obviously, using a lossless audio codec will give you the best possible quality. Popular choices are FLAC and WavPack, with the former being more supported and the latter compressing slightly better (quite similar to HuffYUV and Lagarith, respectively). Neither AVI nor MP4 have native support for these formats, so you'll have to use a superior container to be able to use either of these (i.e. Matroska). The MP4 standard defines a lossless codec, but absolutely no one uses that and support for it is poor on both the encoding and decoding side.
Vorbis and AAC can be considered the best lossy audio codecs. They're quite equal in quality, although Vorbis seems to have a slight edge at high bitrates (> 128kbps) and AAC at lower bitrates (< 128 kbps).
