Struct Configuration

pub struct Configuration { /* private fields */ }

Structure containing configuration for a Fingerprinter.

Implementations

impl Configuration

pub fn with_id(self, id: u8) -> Self

Adds an ID to the configuration.

This ID is used for fingerprint compression.

pub fn with_classifiers(self, classifiers: Vec<Classifier>) -> Self

Adds classifiers to the configuration.

pub fn with_coefficients(self, coefficients: Vec<f64>) -> Self

Updates coefficients for internal chroma filter.

pub fn with_interpolation(self, interpolate: bool) -> Self

Enables or disables interpolation.

pub fn with_frame_size(self, frame_size: usize) -> Self

Sets number of samples in a single frame for FFT.

pub fn with_frame_overlap(self, frame_overlap: usize) -> Self

Sets number of samples overlapping between two consecutive frames for FFT.

pub fn with_removed_silence(self, silence_threshold: u32) -> Self

Enables removal of silence with a specified threshold.

pub fn sample_rate(&self) -> u32

Target sample rate for fingerprint calculation.

pub fn preset_test1() -> Self
