LoopSpark
Live sample remixer in your browser. 8 tracks, ±24 semitone pitch, AI sample generator, auto key + tempo matching. No install. No DAW. Just play.
Added May 8, 2026
https://loopsparkapp.comLoopSpark turns your browser into a live remix instrument.
Drop in 2- 8 samples — from your computer, our built-in Sample Bank, or generated on the fly with Spark AI (powered by ElevenLabs Music) — and LoopSpark instantly:
• Auto-detects key and BPM of every sample (filename → Essentia.js polyphonic analysis → FFT fallback) • Pitch-shifts every track into the same key as your master (relative major/minor aware, so Am and C are treated as the same family) • Time-stretches everything to one tempo with SoundTouch.js, preserving pitch • Lets you push pitch and tempo to extremes (±24 semitones) that traditional DAWs choke on
Then the fun starts: Orbit Mode phrase-mutes tracks on a 1–4 bar brain. Fusion Engine blends tracks in parallel, frequency-split, morph, or master/slave modes. A 12-slot FX Chain, vintage Color Box (Moog-flavored tape character), per-track mini-FX (Comp → Delay → Reverb → Tape → Maximizer), and a full mastering chain (EQ → Comp → Limiter) sit downstream of everything.
Save sessions to the cloud, share remixable links, branch a remix tree, export to WAV. Keyboard shortcuts everywhere. Five themes. Mobile-optimized.
Built 100% on Lovable — React + Web Audio API + WASM DSP, with Lovable Cloud handling auth, sessions, the Spark Vault, and live PayPal billing (Free / $7 Export / $5/mo Creator).
No installs. No accounts to start. Open the tab, drop a sample, hit play. That's it.
