Struct StreamingSpectrogram 

pub struct StreamingSpectrogram { /* private fields */ }

A rolling spectrogram that maintains a sliding window of magnitude frames.

After calling push with audio samples, the latest spectrogram can be retrieved as a Vec<Vec<f32>> of shape (n_frames, n_freq_bins).

Implementations

impl StreamingSpectrogram

pub fn new( stft_config: RingBufferStftConfig, max_frames: usize, ) -> FFTResult<Self>

Create a new streaming spectrogram.

max_frames is the maximum number of magnitude frames retained. Older frames are discarded once the limit is reached.

Errors

Propagates errors from RingBufferStft::new.

pub fn push(&mut self, samples: &[f32])

Push samples and update the spectrogram.

pub fn get_spectrogram(&self) -> Vec<Vec<f32>>

Return the current spectrogram as a Vec<Vec<f32>> of shape (n_frames, n_freq_bins).

pub fn n_freq_bins(&self) -> usize

Number of one-sided frequency bins.

pub fn n_frames(&self) -> usize

Number of frames currently held.
