Hello everyone. I installed FL Studio today just to find out that all channels are marked red because the program doesn't recognize the file format. It happens to be Vorbis, and according to the FAQ it should install itself with FL studio.

It doesn't. In fact, I can't install any ACM codecs. I tried even codec packs and all, but nothing seems to work. I think a fresh windows install will do the trick but, if anyone had a similar problem and found out a way to solve it without a reinstal, I'd ve very grateful.

I'm using Windows XP SP2.

Vorbis via ACM is a bad idea.

care to explain?

also, FL studio (a music producing software) uses it, so it shouldn't be that bad. And I don't have another choice, you don't just switch your music producing software like you switch players...

Vorbis is inherently VBR, where as ACM is inherently CBR. Basically you try to force CBR vorbis or you run into problems by VBR and ACM.

Better would be to use dshow or just interface with Xiph dll's directly.

You can get the vorbis acm codec from www.free-codecs.com (use the newer one, look at the dates, there are 2 versions that I know of)

It should be able to decode a vorbis encoded *.wav file. (I doubt it will work on *.ogg though)

both vorbis acm and lame acm can encode in vbr to a *.wav file, both playback fine in winamp (via in_wave)
sure, acm/wav isn't supposed to support vbr audio.. but neither is avi
