Hi
I am trying to use the Denoise option of speex but unable to do so
successfully. I would really appreciate if some one could help me and
identify what exactly wrong i am doing...
I am using below code to perform denoise.
//Initialize speex preprocess state and set the denoise option
int nEnable = 1;
SpxPreprocessState speex_preprocess_state_init(160,
8000); //20ms audio at 8000 bps
speex_preprocess_ctl(SpxPreprocessState, SPEEX_PREPROCESS_SET_DENOISE,
&nEnable);
//Run the preprocess on the buffer captured before encoding
speex_preprocess_run(SpxPreprocessState, (short*)pbBuffer);
speex_encode_int(EncoderState,(short*)pbBuffer,
&stSpeexBits);
I dump the output of the buffer after calling speex_preprocess_run and play
it using some media player tool but I dont hear any audio as if the complete
audio has been removed. Am i following the right steps, is there else i need
to do along with the steps i have written above.
Thanks
Gurinder
