Install

pip install rmvpe-onnx        # Python API only
pip install rmvpe-onnx[cli]   # with CLI tool

[!TIP] Includes onnxruntime (CPU). For hardware acceleration (CUDA, DirectML, etc.), install a compatible ONNX Runtime variant. See the ONNX Runtime documentation.

CLI

# Download the ONNX model
# [optional] auto-downloaded on first predict if skipped
rmvpe-onnx download

# Run pitch prediction with default settings and plot the results
rmvpe-onnx predict audio.wav --plot

For all options, see the CLI Reference or run rmvpe-onnx download --help and rmvpe-onnx predict --help.

Python API

[!NOTE] The Python API returns raw outputs with no confidence thresholding applied. Use confidence to filter frequency yourself if needed.

from rmvpe_onnx import RMVPE
import soundfile as sf

audio, sr = sf.read("audio.wav")
rmvpe = RMVPE()

time, frequency, confidence, activation = rmvpe.predict(audio=audio, sr=sr)

# Optional: zero out frequency where confidence is below a threshold
# frequency[confidence < 0.03] = 0.0

For full parameter reference and return values, see the API Reference.
