Any reliable way to convert Microsoft ACM audio?

[Zalis116]

If anyone's seen guilty-pleasure anime G-On Riders, then you probably know that the quality of the mid-2002 DivX3 TV-rips is... not good. I'd like to do a re-release someday with improved A/V quality and fix Mugen's questionable translations. However, the audio in the DVD raws I found doesn't want to play nice with any software. It's apparently encoded with some ancient proprietary Microsoft piece of junk known as Audio Compression Manager.

So, does anyone know of a program or method that will convert this audio into something like mp3/ogg/aac? I'd really rather not record the audio in real-time and convert/resync/remux, but it's looking like I might have to.

More details here, including what conversion programs I've tried.

The actual audio file can be found here.

I am not sure what platform you are working on, but on Linux you can simply dump the audio to file (instead of out to the speaker) with mplayer, like this:

Code: [Select]

$ mplayer "file" -novideo -ao pcm

It's possible you can redirect the audio stream with other media players also, check their options.
