AAC 5.1?

[Schizophonic]

Hi

Just a quote from Wiki

Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at many bit rates.

AAC has been standardized by ISO and IEC, as part of the MPEG-2 & MPEG-4 specifications. The MPEG-2 standard contains several audio coding methods, including the MP3 coding scheme. AAC is able to include 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 16 low frequency enhancement (LFE, limited to 120 Hz) channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode, however hi-fi transparency demands data rates of at least 128kbit/s (VBR). The MPEG-2 Audio tests showed that AAC meets the requirements referred to as "transparent" for the ITU at 128 kbit/s for stereo, and 320kbit/s for 5.1 audio.

The reason why i want to know or to be sure is that I've got a .mkv file with 5.1 sound. I know the IPOD supports AAC file types.

In theory if I extract the audio from the .mkv file and convert it to AAC with 320kbit and put it on my ipod. Pluging it into my car via IPOD connection (not AUX) will i be able to listen to 5.1 throug my head unit?

'Fraid not, the ipod can only output stereo as far as i know. I doubt it could decode a file with more than 2 channels anyway.
