praat-wasm demo gallery

A practical tour of common Praat tasks: sound generation, acoustic analysis, TextGrid authoring, batch scripting, worker execution, and real audio inspection.

Not initialized

1) Synthesize and inspect a sound

Generate a configurable pure tone, inspect metadata, and listen immediately.

Frequency (Hz) Duration (s) Sample rate (Hz)

Run this demo to generate audio.

0:00 / --:--

Ready.

2) Acoustic analysis pipeline

Tune analysis parameters and inspect generated Praat analysis objects.

Source freq (Hz) Duration (s) Sample rate (Hz) Pitch floor/ceiling

Run this demo to generate audio.

0:00 / --:--

Ready.

3) Load generated WAV data

Configure the sweep generator instead of relying on hard-coded values.

Start freq (Hz) End freq (Hz) Duration (s) Sample rate (Hz)

Run this demo to generate audio.

0:00 / --:--

Ready.

4) Build and export a TextGrid

Edit timeline duration, boundaries, and labels; render and audition locally.

Timeline duration (s) Reference freq (Hz) Boundaries CSV (seconds) Interval labels CSV

Run this demo to generate reference audio.

0:00 / --:--

No TextGrid loaded yet.

Run this module to populate the TextGrid viewer.

Ready.

5) Batch style processing

Provide your own frequency list to generate and summarize batches.

Frequencies CSV (Hz) Duration per sound (s) Sample rate (Hz)

Run this demo to generate audio.

0:00 / --:--

Ready.

6) Analyze user audio + worker mode

Upload audio, inspect it locally in this card, and configure worker-side synthesis.

Worker tone freq (Hz) Worker tone duration (s) Worker sample rate (Hz)
