Struct QualityAssessor 

pub struct QualityAssessor { /* private fields */ }

Audio quality assessor with configurable sample rate.

Computes multi-dimensional quality metrics for audio chunks, providing objective measures for quality gates and filtering.

Implementations

impl QualityAssessor

pub fn new(sample_rate: u32) -> Self

Creates a new quality assessor for the given sample rate.

Arguments

• sample_rate: Audio sample rate in Hz (e.g., 16000)

Example

use speech_prep::preprocessing::QualityAssessor;

let assessor = QualityAssessor::new(16000);

pub fn assess(self, samples: &[f32]) -> Result<QualityMetrics>

Assesses audio quality for the given samples.

Computes SNR, energy, spectral centroid, and unified quality score.

Arguments

• samples: Audio samples to assess (must not be empty)

Returns

Quality metrics including SNR (dB), energy, spectral centroid (Hz), and unified quality score [0.0, 1.0].

Errors

Returns Error::InvalidInput if samples are empty.

Example

use speech_prep::preprocessing::QualityAssessor;

let assessor = QualityAssessor::new(16000);
let audio = vec![0.5f32; 16000];
let metrics = assessor.assess(&audio)?;
assert!((0.0..=1.0).contains(&metrics.quality_score));
