Struct BeatThis 

pub struct BeatThis<S: InferenceSession> {
    pub mel: MelProcessor<S>,
    pub inference: BeatInference<S>,
    pub post: PostProcessor,
}

High-level beat tracker composing the full pipeline.

Owns the mel spectrogram model, the beat inference model, and the post-processor. Generic over the inference session type, so it works with any backend (ort, rten, tract).

Fields

mel: MelProcessor<S>

inference: BeatInference<S>

post: PostProcessor

Implementations

impl<S: InferenceSession> BeatThis<S>

pub fn new<R: InferenceRuntime<Session = S>>( runtime: &R, mel_model_path: &Path, beat_model_path: &Path, ) -> Result<Self>

Create a new beat tracker by loading both ONNX models via the given runtime.

• runtime: any InferenceRuntime (e.g. OrtRuntime::default())
• mel_model_path: path to the mel spectrogram ONNX model
• beat_model_path: path to the beat tracking ONNX model

pub fn process_file(&mut self, path: &Path) -> Result<BeatResult>

Run the full pipeline on an audio file.

Loads the file, resamples to 22050 Hz mono, computes mel spectrogram, runs beat inference, and post-processes into beat/downbeat timestamps.

pub fn process_audio( &mut self, samples: &[f32], sample_rate: u32, ) -> Result<BeatResult>

Run the full pipeline on raw audio samples.

The samples are resampled to 22050 Hz if sample_rate differs. Input should be mono f32 PCM.
