[−][src]Struct webrtc_vad::Vad
Methods
impl Vad
[src]
pub fn new(sample_rate: i32) -> Result<Vad, ()>
[src]
Creates and initializes a VAD instance.
On success, returns a pointer to the new VAD instance, which should eventually be deleted using fvad_free().
Panics in case of a memory allocation error.
Returns Err(()) if an invalid sample rate was specified.
pub fn reset(&mut self)
[src]
Reinitializes a VAD instance, clearing all state and resetting mode and sample rate to defaults.
pub fn set_sample_rate(&mut self, sample_rate: i32) -> Result<(), ()>
[src]
Sets the input sample rate in Hz for a VAD instance.
Valid values are 8000, 16000, 32000 and 48000. The default is 8000. Note that internally all processing will be done 8000 Hz; input data in higher sample rates will just be downsampled first.
Returns Err(())
if sample rate is not valid.
pub fn fvad_set_mode(&mut self, mode: VadMode) -> Result<(), ()>
[src]
Changes the VAD operating ("aggressiveness") mode of a VAD instance.
A more aggressive (higher mode) VAD is more restrictive in reporting speech. Put in other words the probability of being speech when the VAD returns 1 is increased with increasing mode. As a consequence also the missed detection rate goes up.
Valid modes are 0 ("quality"), 1 ("low bitrate"), 2 ("aggressive"), and 3 ("very aggressive"). The default mode is 0.
Returns Ok(()) on success, or Err(()) if the specified mode is invalid.
pub fn is_voice_segment(&mut self, buffers: &[i16]) -> Result<bool, ()>
[src]
Calculates a VAD decision for an audio frame.
frame
is an array of length
signed 16-bit samples. Only frames with a
length of 10, 20 or 30 ms are supported, so for example at 8 kHz, length
must be either 80, 160 or 240.
Returns : Ok(true) - (active voice), Ok(false) - (non-active Voice), Err(()) - (invalid frame length).
