No audio decompressor could be found to decompress the source audio format.

I am trying to save a WAV in VirtualDubMod so I can use Lame and encode it to CBR MP3. The source format it's in now is MPEG-1 layer 1, 2. Here is the error I get while clicking the save WAV and I get the error after I enter a name and click save.

The source may have MP3 audio already.
If you haven't already installed an MP3 CODEC:-

Download and unzip Lame 3.98 to a folder.
http://www.rarewares.org/mp3-lame-bundle.php

Right click on LameACM.inf and select 'Install' from the menu.

Try VirtualDubMOD again.

I already have Lame and the error above is the first time I got it. Normally I am able to save it but it won't let me DeMux it nor save it as WAV.

Suggest you drop the file into GSpot and post the result.
