Configuration for spectrogram computation.

Fields

n_mels: usize

Number of mel frequency bands.

n_fft: usize

FFT window size in samples.

hop_length: usize

Hop size between frames in samples.

sample_rate: u32

Sample rate of the input audio.

f_min: f32

Minimum frequency for mel filterbank (Hz).

f_max: f32

Maximum frequency for mel filterbank (Hz).

log_scale: bool

Whether to apply log scaling.

ref_db: f32

Reference value for dB conversion.

min_value: f32

Minimum value for log scaling (avoids log(0)).

Implementations

impl SpectrogramConfig

pub fn for_5s_segment() -> Self

Creates a config optimized for 5-second segments producing 500 frames.

For 32kHz audio:

• 5s = 160,000 samples
• hop_length = 320 gives ~500 frames

pub fn with_target_frames( target_frames: usize, duration_ms: u64, sample_rate: u32, ) -> Self

Creates a config for variable-length audio.

Trait Implementations

impl Clone for SpectrogramConfig

fn clone(&self) -> SpectrogramConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpectrogramConfig

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

Formats the value using the given formatter.

impl Default for SpectrogramConfig

fn default() -> Self

Returns the “default value” for a type.
