Pitch detection object

Implementations

impl Pitch

pub fn new( method: PitchMode, buf_size: usize, hop_size: usize, sample_rate: u32, ) -> Result<Self>

Creation of the pitch detection object

• method Pitch detection algorithm
• buf_size Size of the input buffer to analyse
• hop_size Step size between two consecutive analysis instant
• sample_rate Sampling rate of the signal

pub fn with_tolerance(self, tolerance: Smpl) -> Self

Change yin or yinfft tolerance threshold

pub fn with_silence(self, silence: Smpl) -> Self

Set the silence threshold of the pitch detection object

pub fn with_unit(self, unit: PitchUnit) -> Self

Set the output unit of the pitch detection object

pub fn get_hop(&self) -> usize

Get hop size

pub fn do_<'i, 'o, I, O>(&mut self, input: I, output: O) -> Status

where I: Into<FVec<'i>>, O: Into<FVecMut<'o>>,

Execute pitch detection on an input signal frame

• input Input signal of size hop_size
• output Output pitch candidates of size 1
