Trimming AAC audio without re-encoding?

[hello_hello]

Ideally I'm looking for an AAC equivalent of mp3directcut (http://mpesch3.de1.cc/mp3dc.html), but is there a similar program which allows just the trimming/cutting/joining of AAC files without re-encoding? Something which could let me trim unnecessary silence if need be etc. That sort of thing.

Thanks.

To trim/cut you can use BeSplit command line (suplied now with MeGUI) or put in mp4 container and cut with YAMB.

To join similar aac's (ADTS header) you can use the OS command:
copy /b 1.aac + 2.aac full.aac

Nothing for AAC files in mp3directcut vain? Or for m4a or mp4?

I was hoping for something which would let me open an AAC audio file as mp3directcut does with MP3 and give some visual representation to help delete unnecessary silence etc. As AAC is so popular now I'd have thought there'd be something.

Thanks for the info but I don't think it'll be practical for cleaning a bit of silence from the start or end of a bunch of songs. I might have to re-rip them as wave files and clean them up first, then convert to AAC again. Bummer....

You can remux to mka using mkvtoolnix (http://www.bunkus.org/videotools/mkvtoolnix/) then open it in VirtualDub + Matroska input plugin + AAC ACM Codec (http://forums.virtualdub.org/index.php?act=ST&f=7&t=19488).
Then you can cut it in direct stream copy (so no loss in quality).
