Export to WAV... problems

[dpchrist]

audacity:

I am an Audacity newbie who has recorded some audio using Audacity and saved the Audacity project. The project opens fine and the audio plays correctly inside Audacity, but when I choose File | Export to WAV..., I get a *.wav file containing white noise of the same length as my audio. Checking Edit | Preferences... | File Formats, Uncompressed Export Format is set to WAV (Microsoft 16 bit PCM). If I set it to WAV (Microsoft 32 bit float), I get a *.wav file containing silence of the same length as my audio. 16 bit AIFF yields white noise. mp3 works as expected.

I used Audacity to record audio and make a *.wav file back in July, and everything worked as expected. Since then, I tried to work with some *.avi files and went through several gyrations installing/ uninstalling codecs. I suspect that a bad and/or misconfigured audio codec is the source of this Audacity problem, but don't know where to look for the codecs nor how to determine if they're good/bad and/or installed/configured correctly.

Any suggestions?

TIA,

David

That's really bizarre. The first thing to do is try using Audacity 1.3.3 (which can be installed at the same time as 1.2.6).

Does anyone know if Audacity uses any of the codecs that Windows knows about? I thought it supplied all it's own code to import / export to each format.
