Web DJ

Turn any webpage into a live DJ instrument with sampler pads, mixer, effects, sequencer, and audio-reactive visuals. Web DJ transforms your browser into a fully-featured DJ workstation. Capture audio from any webpage, load it into sampler pads, apply real-time effects, build beats with a step sequencer, and visualize your mix — all from a sleek side panel that works alongside any website. Trigger sounds instantly with a 16-pad grid: • Built-in samples: kick, snare, hi-hat, clap, tom, cymbal, bass, synth • Capture audio from any webpage element and assign it to a pad • Keyboard shortcuts for every pad (Q-V, 1-4 for fast triggering) Scan any webpage to detect audio, video, and embedded media elements. Capture sound from any detected source, trim it with a waveform editor, and assign the clip to a sampler pad. Works on YouTube, SoundCloud, Spotify Web, podcasts, and any other site with playable media. After capturing audio, open the trim modal to fine-tune your sample: • Visual waveform display on canvas • Draggable start and end handles • Preview trimmed clip before saving • Assign directly to any pad Control your mix with professional-grade tools: • Master volume fader (0–100%) • VU meter for real-time level monitoring • A/B crossfader for blending between sources Shape your sound with real-time effect processing: • Reverb — adjustable wet mix for spatial depth • Delay — configurable time, feedback, and wet mix • Filter — lowpass, highpass, and bandpass with frequency and resonance controls • Distortion — adjustable amount and wet mix for grit and texture Build drum patterns and loops: • Transport controls: play, stop, record • BPM control (40–300 BPM) with increment/decrement buttons • Visual step grid for programming beats • Clear pattern or export loop as audio Watch your mix come alive with three visualization styles: • Bars — frequency spectrum display • Wave — waveform oscilloscope • Circular — radial polar visualization Toggle on/off from the side panel.
