Function Documentation

int speex_preprocess (  SpeexPreprocessState *  st, float *  x, float *  noise )

Preprocess a frame

int speex_preprocess_ctl (  SpeexPreprocessState *  st, int  request, void *  ptr )

Used like the ioctl function to control the preprocessor parameters

void speex_preprocess_estimate_update (  SpeexPreprocessState *  st, float *  x, float *  noise )

Preprocess a frame

void speex_preprocess_state_destroy (  SpeexPreprocessState *  st  )

Destroys a denoising state

SpeexPreprocessState* speex_preprocess_state_init (  int  frame_size, int  sampling_rate )

Creates a new preprocessing state
