Has anyone been able to get this "audio" format to work? I've been trying this format as well as wma but neither of them work!

I am on firmware version 2.71 and I know they are supposed to support those formarts. I get "corrupt data" for mp4 audio files and unsupported format for wma files! Yes I'm sure I'm on 2.71, it says so on the PSP when I check under system information. The program I used to convert the files is ImTOO.

Can anyone help?

It's enabled.....however I tried a newer version of the ImTOO converter and wma worked, however I still can't get mp4, m4a, acc too work!

I'm really just trying to find a format that gives the most compression and the least audio quality loss! Below is what they said about the 2.0 firmware and audio support!

System Software Ver. 2.00 (August 24, 2005)

Music

The combination of SonicStage? version 3.2 (or later) and PSP® system software 2.00 (or later) has made it possible for music files in ATRAC3 plus format to be transferred to a Memory Stick PRO Duo?
MP4 (the audio codec for MP4 format audio files is MPEG-4 AAC) and WAV (Linear PCM) have been added as playable file formats (for music saved on Memory Stick Duo? media).

How do you convert MP3 audio into MP4 audio? Or is it even possible if not what the heck was sony talkin about in the release of 2.0?

I got mp4 and m4a formats to work! I used a program called MediaCoder. There are several audio settings but I used the audio settings for the iPod and the PSP played both formats!

I still would like to know which format gives the best compression without much audio quality loss....

When I tested both mp3 and mp4 (AAC) format, the mp3 sounded better and also was smaller in file size by a few points...I don't know if it's because of the program I am using though!
