A research repo for the WaveKat project — interactive tools and Jupyter notebooks for working with audio models (VAD, turn detection, voice datasets, and more).

[!WARNING] Early development. Things may change.

What's In Here

wavekat-lab/
├── tools/
│   ├── audio-lab/     Real-time VAD + Turn Detection + ASR comparison app (Rust + React)
│   └── cv-explorer/   Mozilla Common Voice dataset browser (Cloudflare Workers + React)
├── notebooks/         Jupyter notebooks (training, validation, dataset splits)
└── docs/              Plans and design docs

Each tool is self-contained — its own Makefile, lockfiles, and build setup live inside its folder.

Tools

Audio Lab — tools/audio-lab/

Web app for testing and comparing WaveKat library backends side by side in real time. Live mic capture, WAV upload, multi-config fan-out, VAD-gated pipeline mode, live ASR transcripts, waveform + spectrogram + probability timelines.

Backends: webrtc-vad, silero-vad, ten-vad, firered-vad, pipecat smart-turn, sherpa-onnx ASR. Details →

Common Voice Explorer — tools/cv-explorer/

Web app for browsing and playing audio clips from the Mozilla Common Voice dataset. Filter by locale, split, demographics, and search sentences — with waveform playback powered by WaveSurfer.js. Built on Cloudflare Workers + D1 + R2. Details →

Live: https://commonvoice-explorer.wavekat.com/

Notebooks

notebooks/ is the home for Jupyter notebooks covering training, validation, and dataset-splitting workflows. Python env is managed by uv.

make setup-notebooks   # one-time: uv sync the notebook env
make lab               # start Jupyter Lab on notebooks/

Repo Layout Conventions

• Per-tool Makefiles — tools/<name>/Makefile owns dev/build/CI for that tool. Run cd tools/<name> && make help to see what's there.
• Root Makefile — repo-wide only: setup, lab, ci, and per-tool CI delegators.
• No shared Cargo workspace at root — each Rust tool keeps its own Cargo.toml / Cargo.lock / target/ inside its folder.

About WaveKat

wavekat-lab is part of WaveKat, an open-source ecosystem for building real-time voice pipelines. This repo holds interactive tools and notebooks for experimenting with the audio models — VAD, turn detection, and more — that power those pipelines.
