Hi,

I have searched, but I have not found an answer to my question. I am just wondering if it is possible to trim an m4a audio file losslessly. I have some songs that were recorded live that I would like to trim the beginnings and ends of. Since I am not doing anything else to the file, is there a way to do this losslessly? Thanks.

See here for a nice walkthrough: http://forum.doom9.org/showthread.php?t=93240

No GUI though, you'll have to use good ol' command line wink.gif

If you are using iTunes / iPods to playback the file you can set start and end points for the file in the get info window.

You can also use QuickTime Pro to edit m4a file losslessly.
Just choose "Pass Through" in MP4 export options, and QuickTime will process audio file without re-encoding.
