Struct PitchEstimate 

pub struct PitchEstimate {
    pub period_samples: f32,
    pub f0_hz: f32,
    pub confidence: f32,
}

Result of a pitch-estimation pass on one 20 ms frame.

Fields

period_samples: f32

Pitch period in samples at 8 kHz. Fractional — either an integer or integer + 0.5 on the IMBE pitch grid.

f0_hz: f32

Fundamental frequency in Hz (8000 / period_samples).

confidence: f32

Confidence score in [0, 1], computed as 1 − E(p) at the chosen pitch. Values above ≈0.5 typically indicate stable voiced speech; below ≈0.05 indicates noise or silence and is the trigger for the encoder to emit AMBE_SILENCE.

Trait Implementations

impl Clone for PitchEstimate

fn clone(&self) -> PitchEstimate

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PitchEstimate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PitchEstimate

fn eq(&self, other: &PitchEstimate) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
