I am neebie to speex. Just compiled latest release with Visual Studio 2005. But as I was using testdenoise.exe with raw PCM audio input, output signal was like all pulled toward +1 or -1 and sounds like all noise. I tracked the code and it did appear that AGC and other pre-processing were turned off. What did I do wrong? Thanks for any direction. -Peng -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/speex-dev/attachments/20081128/babb7b54/attachment.htm
