[Speex-dev] Denoise not working for me

[Gurinder Singh]

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
