Speex dev - Sep 2011 - Serial number in OGG stream

Hello,

I'm using Speex Preprocessor to supress noise, eliminate echo etc.
But I have another preprocessor state that I want to use ONLY to determine
voice activity.

int res = speex_preprocess_run(m_VADOnly, (spx_int16_t *)
pStreamSampleBuffer);

pStreamSampleBuffer is modified after call to speex_preprocess_run.
I have manually turned off noise suppression and AGC but anyway - VAD
modifies my data.

Is there a solution? All I want is to know whether voice present or not.. I
do not need any voice modifications itself.

Thanks a lot!

Regards,
Anton

Hi All,

   I am using the OGG stream format for the speex output and what does the
serial number signifies in it? because in speex it is set to a random number.

yes it should be set to a random number when a new stream is started.

It is just a unique identifier within a multitrack file, eg. if you
had a speex audio track multiplexed with a theora video track, they
would need different ogg serial numbers. It doesn't matter what the
actual numbers are (they don't signify anything), just that they are
different
