Struct AudioSegmentFingerprint 

pub struct AudioSegmentFingerprint {
    pub bytes: Vec<u8>,
    pub sample_count: usize,
    pub sample_rate: u32,
}

A compact fingerprint for an audio segment based on sub-band energy ratios.

The fingerprint is computed by:

1. Dividing the audio into short frames (default 64 ms)
2. Computing the energy in each of 8 frequency sub-bands
3. Encoding the sign of inter-band energy differences as bits

This produces a bit-string that is robust to small amplitude changes and can be compared with Hamming distance for near-duplicate detection.

Fields

bytes: Vec<u8>

Raw fingerprint bytes (1 byte per analysis frame).

sample_count: usize

Number of audio samples analysed.

sample_rate: u32

Sample rate used during fingerprinting.

Implementations

impl AudioSegmentFingerprint

pub fn hamming_distance(&self, other: &Self) -> usize

Hamming distance between two fingerprints (proportional to byte length difference).

pub fn similarity(&self, other: &Self) -> f64

Similarity in [0.0, 1.0].

pub fn is_similar(&self, other: &Self, threshold: f64) -> bool

Returns true if similarity ≥ threshold.

Trait Implementations

impl Clone for AudioSegmentFingerprint

fn clone(&self) -> AudioSegmentFingerprint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AudioSegmentFingerprint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for AudioSegmentFingerprint

impl PartialEq for AudioSegmentFingerprint

fn eq(&self, other: &AudioSegmentFingerprint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
