pub struct MelProcessor<S: InferenceSession> { /* private fields */ }Expand description
Computes log-mel spectrograms via an ONNX model.
The model takes raw PCM audio and returns a mel spectrogram, guaranteeing exact numerical parity with the Python training pipeline.
Implementations§
Source§impl<S: InferenceSession> MelProcessor<S>
impl<S: InferenceSession> MelProcessor<S>
Sourcepub fn new(session: S) -> Self
pub fn new(session: S) -> Self
Wrap an already-loaded inference session for the mel spectrogram model.
Sourcepub fn session_mut(&mut self) -> &mut S
pub fn session_mut(&mut self) -> &mut S
Get a mutable reference to the underlying session.
Sourcepub fn process(&mut self, samples: &[f32]) -> Result<Tensor>
pub fn process(&mut self, samples: &[f32]) -> Result<Tensor>
Compute mel spectrogram from mono PCM samples at 22050 Hz.
Input: mono f32 samples (any length).
Output: Tensor with shape [1, time_frames, 128].
The number of time frames depends on sample count:
time_frames ≈ samples.len() / 441 (hop_length=441 for 50 fps at 22050 Hz).
