From WAV to m4a Apple Lossless

Post by Snowrider » Sat Oct 13, 2007 1:21 am

I wish to convert all my .wav files to .m4a to be used on my Apple TV and iPod. I have tagged all my .wav files using Media Monkey and all the files work well with my Sonos system. When I attempted to convert using MAX I found that the tag info on my .wav files is not being picked up by MAX. Is there some setting within MAX that I am missing?

If MAX can't do the job for me is there another application that will work for me? I have >500 CDs ripped in wav and I am looking to do this as painlessly as possible.

Thanks for looking and any help is appreciated.

WAV (the file container) don't support tags. At least not following its specification.
So no wonder Max don't pick up any tags...

I have seen WAVs with metadata, specifically it was ID3v2 tags embedded in an 'id3 ' chunk by MusicMatch jukebox. I wrote some additional classes for TagLib to support parsing and metadata extraction for these WAVs, but I trashed the code afterward because I didn't think I'd need it again. But, as krmathis stated, this is somewhat nonstandard and isn't handled by Max.

If you want to send me one of the WAVs I will take a look at it and see how the metadata is stored.
