Build drum patterns with a 16-step sequencer — all sounds synthesized in your browser.
Beat Maker is a 16-step drum sequencer that synthesizes all sounds using the Web Audio API — no sample files needed. Each column represents one 16th-note step. Click cells to toggle hits on or off. Use the BPM slider to set the tempo and the Swing slider to add rhythmic groove. Each instrument row has its own volume slider. Export your pattern as a 4-bar WAV file to use in other projects.
Listen to sounds through your microphone and visualize their frequency and volume in three different styles: bars, waveform, and a circular view.
Tune your guitar using your microphone. Visualize audio frequency data, detect pitches, and see hints to tune each string up or down.
Convert text to speech with voice selection and speed controls, or transcribe speech to text in real-time. Uses built-in browser APIs — zero dependencies, total privacy.
Clean up noisy audio recordings directly in your browser using Web Audio API filtering. Apply high-pass and low-pass filters, a dynamics compressor, and a noise gate to remove hum, hiss, and background noise from voice recordings, podcasts, and more.
