Good idea!

 

I'd forgotten about all the goodies - including source code - in the GSM etc standards.

Hi, Richard

 

Both ITU G.723.1 and G.729 provide VAD algorithm/c code. They perform well in modest SNR environment.

Hi,

Does anyone have any idea where I can find some simple algorithms/code to allow the presence or absence of speech in a signal to be
