StreamingExtractor

pub(all) struct StreamingExtractor {
  config : @1zhouhaoran1/moonmel/src/core/types.FeatureConfig
FeatureConfig
  window : Array[Double]
  filterbank : @1zhouhaoran1/moonmel/src/core/types.FeatureMatrix

}

StreamingExtractor::available_frames

source

fn StreamingExtractor::available_frames(self : StreamingExtractor) -> Int

Returns the number of ready full frames available for extraction.

StreamingExtractor::buffered_samples

source

fn StreamingExtractor::buffered_samples(self : StreamingExtractor) -> Int

Number of retained samples, excluding any pending gap for hop > n_fft.

StreamingExtractor::new

source

fn StreamingExtractor::new(config? : @1zhouhaoran1/moonmel/src/core/types.FeatureConfig
FeatureConfig) -> Result[StreamingExtractor, @1zhouhaoran1/moonmel/src/core/types.MelError
MelError]

Create a new streaming extractor with precomputed window and filterbank.

StreamingExtractor::pop_features

source

fn StreamingExtractor::pop_features(self : StreamingExtractor) -> Result[StreamingFeatures, @1zhouhaoran1/moonmel/src/core/types.MelError
MelError]

Consume ready frames once and derive Mel, Log-Mel and MFCC from shared Mel data. Calling separate pop methods consumes different batches; use this for aligned outputs.

StreamingExtractor::pop_mel_frames

source

fn StreamingExtractor::pop_mel_frames(self : StreamingExtractor) -> @1zhouhaoran1/moonmel/src/core/types.FeatureMatrix
FeatureMatrix

Process and consume ready frames, returning a Mel Spectrogram matrix [n_mels][n_frames].

StreamingExtractor::pop_mfcc_frames

source

fn StreamingExtractor::pop_mfcc_frames(self : StreamingExtractor) -> @1zhouhaoran1/moonmel/src/core/types.FeatureMatrix
FeatureMatrix

Process and consume ready frames, returning an MFCC matrix [n_mfcc][n_frames].

StreamingExtractor::push_samples

source

fn StreamingExtractor::push_samples(self : StreamingExtractor, chunk : Array[Double]) -> Unit

Push newly arrived audio samples to the streaming buffer.

StreamingExtractor::reset

source

fn StreamingExtractor::reset(self : StreamingExtractor) -> Unit

Clear remaining samples in buffer.

StreamingExtractor::try_push_samples

source

fn StreamingExtractor::try_push_samples(self : StreamingExtractor, chunk : Array[Double]) -> Result[Unit, @1zhouhaoran1/moonmel/src/core/types.MelError
MelError]

Validate a complete chunk before appending any samples. Empty chunks are no-ops. Use this API for untrusted input; legacy push_samples accepts unchecked PCM.
