Struct imbe::descramble::VoiceDecisions

pub struct VoiceDecisions { /* fields omitted */ }

Tracks harmonic voiced/unvoiced decisions.

The decisions are initialized from the received "tilde" v_l vector [p25-26], and then may be modified by adaptive smoothing to force certain harmonics as voiced [p49], which forms the "overbar" v_l vector.

Methods

impl VoiceDecisions

pub fn new(voiced: u32, params: &BaseParams) -> VoiceDecisions

Create a new VoiceDecisions from the given band voiced/unvoiced bitmap, b₁, and frame parameters.

pub fn force_voiced(&mut self, l: usize)

Force the given harmonic to be voiced.

pub fn unvoiced_count(&self) -> u32

Compute the number of unvoiced spectral amplitudes/harmonics, L_uv.

pub fn is_voiced(&self, l: usize) -> bool

Check if the given harmonic is voiced.
