Fingerprinter

Struct Fingerprinter 

Source
pub struct Fingerprinter { /* private fields */ }
Expand description

Main entry point for audio fingerprinting.

Provides a streaming push-based API: create, start, feed samples, finish, then retrieve the fingerprint.

Implementations§

Source§

impl Fingerprinter

Source

pub fn new(algorithm: Algorithm) -> Self

Create a new fingerprinter for the given algorithm.

Source

pub fn start(&mut self, sample_rate: u32, num_channels: u16) -> Result<()>

Start processing a new audio stream.

Source

pub fn feed(&mut self, samples: &[i16]) -> Result<()>

Feed interleaved PCM i16 samples into the fingerprinter.

Source

pub fn finish(&mut self) -> Result<()>

Finish processing and flush remaining data.

Source

pub fn fingerprint(&self) -> &[u32]

Get the raw fingerprint (array of 32-bit sub-fingerprints).

Source

pub fn encode(&self) -> String

Get the compressed base64-encoded fingerprint string.

Source

pub fn hash(&self) -> u32

Get the SimHash of the fingerprint.

Source

pub fn algorithm(&self) -> Algorithm

Get the algorithm used by this fingerprinter.
