Play AAC files on SX1?

Have been looking around for it, but not yet seen on the net. There is an app wich runs OGG files but the main app on the X and SX1 supports only mp3 audio.

I think you'll have to change AAC to mp3...

You would need the O2 MusicEdition Firmware.
And then encode your files with Nero, iTunes doesn't work.

If the Siemens SX1 is supposed to play *.aac files (not *.m4a from iTunes) which I don't know, you can use any MP4 file muxer to extract an AAC file from the MP4 container without changing the sound. A command line tool for this is mp4creator from MPEG4IP, a GUI version is called mp4UI. Another GUI is "Ivan & Menno" from Speek, and foobar2000 can also do this with the foo_mpeg4u.dll plugin. See the Audiocoding.com Wiki for more, e.g. the page about MP4 or about FAAC (open source AAC encoder):

You could also use dbpoweramp, thats got an AAC capable encoder (which is a very pleasant surprise).

Remember that (so far at least) its only the O2 Music Edition of the SX1 that supports AAC playback.

That's right, dBpowerAMP offers several AAC encoders in its codec central, one of them being FAAC. The default one is (or was maybe) PsyTEL FastEnc which is very buggy at low bitrates, so you might want to update it either to PsyTEL AACEnc (very slow) or FAAC. I don't know if dBpowerAMP has an option to produce AAC files instead of MP4 on default, but there is at least another "codec" GUI which simply uses mp4creator to multiplex and extract AAC files to and from MP4.

By the way, do you know if the O2 Music Editon of the SX1 also supports the HE AAC (= aacPlus) profile? Their O2 Digital Music Player does at least...
