Remix Tool AI

Where a stem pack gives you raw material, this tool hands you rendered, shareable versions. Slowed + Reverb does the authentic vinyl-style slowdown — the playback clock itself is resampled, so speed and pitch fall together like a turntable at 0.85× — followed by a five-tap echo plate whose wet level you control. Nightcore is the same trick in reverse (default 1.25×, pitch and tempo rise together) with a treble lift. 8D Audio pans a sine LFO at 0.125 Hz, one full rotation around your head every eight seconds. Club Edit boosts 90 Hz bass and air, then compresses and limits for DJ systems; Radio Edit polishes EQ and finishes with the same two-pass linear loudnorm used by the mastering chain, landing at the -14 LUFS streaming floor. The three stem versions run the local HT-Demucs ONNX model once and recombine: instrumental (drums + bass + other), acapella (vocals cleaned by high-pass and de-mud EQ), and drums & bass. Every render passes a true-peak limiter at -1 dBFS so nothing clips on social platforms. Pick any mix of styles; each becomes its own file in the ZIP with a manifest and README. Source separation is not lossless — expect a little bleed on stem versions.
