Constantbackground noise
Hi John,
I noticed the values after decode is very much different from the values
of the original PCM samples. For cases when the PCM sample values are
constant (because no one is speaking), the decoded values fluctuate too.
These fluatuations are causin...

could be a million different things, unfortunately. Focus on comparing
your code to the Speex examples, and looking for places where they
diverge. Also, try taking Speex out of the picture altogether, just to

Yes,
it's necessary; Speex will encode signed 16-bit PCM data and decode to
the same format. See the examples that come with
it.
8-bit audio is not something you would ever want to
use.

At
first glance it looks like you are opening the output device in 8-bit mode (m_waveFormatEx.wBitsPerSample
=8;). You will need to use 16-bit
mode if you expect to write an array of signed short integers to the audio
buffer. 8-...

Have you tried starting with sampleenc/sampledec instead of doing
everything from scratch. That and the manual should contain everything
that's needed.

Hi,
I am developing a peer-to-peer video conference application which uses speex as a codec for the voice.
I am new to speex, so please bear with me if I asked the obvious. After I added the encode and decode function to my MFC app, I heard a constant background noise, even when no one is speaking into the microphone.

The application is coded in MFC C++. The record
