Struct Panako 

pub struct Panako { /* private fields */ }

Panako offline fingerprinter.

Example

use audiofp::{AudioBuffer, Fingerprinter, SampleRate};
use audiofp::classical::Panako;

let mut fp = Panako::default();
let samples = vec![0.0_f32; 8_000 * 3];
let buf = AudioBuffer { samples: &samples, rate: SampleRate::HZ_8000 };
let fpr = fp.extract(buf).unwrap();
assert_eq!(fpr.frames_per_sec, 62.5);
assert!(fpr.hashes.is_empty());

Implementations

impl Panako

pub fn new(cfg: PanakoConfig) -> Self

Build a Panako extractor with the given config.

Trait Implementations

impl Default for Panako

fn default() -> Self

Returns the “default value” for a type.

impl Fingerprinter for Panako

type Output = PanakoFingerprint

The fingerprint produced by this extractor (e.g. Vec<WangHash>).

type Config = PanakoConfig

Per-instance configuration this fingerprinter exposes to callers.

fn name(&self) -> &'static str

Stable identifier for the algorithm and version, e.g. "wang-v1". Useful when persisting fingerprints alongside the producer name.

fn config(&self) -> &Self::Config

Borrow the configuration this instance was built with.

fn required_sample_rate(&self) -> u32

Sample rate, in hertz, the fingerprinter expects its input at. Resampling is the caller’s responsibility.

fn min_samples(&self) -> usize

Minimum buffer length, in samples, required to extract anything. Calls with shorter inputs return AfpError::AudioTooShort.

fn extract(&mut self, audio: AudioBuffer<'_>) -> Result<Self::Output>

Compute the fingerprint of audio.
