Professional audio tools — built by DJ Andy'K
Three steps to a professional master
Everything runs in your browser — private, fast, and powered by the Web Audio API.
Upload Your Track
Drop your MP3 or WAV. Your audio stays entirely in your browser — 100% private, never sent to any server.
Smart Audio Processing
Browser-based DSP engine analyses loudness, applies precision EQ, and masters to industry standards in seconds.
Compare & Download
Hear the A/B difference, review LUFS stats, and download your mastered WAV — all within your browser.
Everything in one place
Professional tools for producers and DJs. Browser-native DSP — no plugins.
Mastering Tool
Normalize to -14 LUFS (Spotify standard), apply EQ, stereo widening, and limit to -0.3 dBTP. Includes A/B waveform compare, presets, and reference track analysis.
BPM + Key Detector
Instant BPM via autocorrelation, musical key via Krumhansl-Schmuckler, Camelot wheel, Tap BPM, danceability score, and analysis history.
DJ Set Planner
Drag & drop tracks, auto-sort by Camelot key, visualise energy flow, see transition quality labels, and export your set.
Track Comparator
Upload two tracks and compare waveforms, LUFS levels, and frequency content side-by-side. Spot the mix differences instantly.
Chord Generator
Generate chord progressions in any key, explore voicings, and preview how chords sound together — built for producers and songwriters.
Metronome
Precision browser metronome with adjustable BPM, time signatures, accent patterns, and tap tempo — zero latency via Web Audio API.
Loudness Meter
Real-time LUFS, RMS, and true-peak metering in your browser. Measure loudness against Spotify, Apple Music, and YouTube targets.
Stem Splitter
Separate vocals, drums, bass, and other stems from any track — entirely in the browser. No uploads, no servers, complete privacy.
Built from a real workflow
Andy'K Music Lab was created from the real workflow of DJ Andy'K — from preparing tracks for release to analysing loudness, BPM, key, transitions and final sound.
Every producer knows the same problem: too many tools, too many plugins, too many steps. The Lab brings the essential music preparation workflow into one clean browser-based space.
It is not built to replace creativity. It is built to protect it.
“Music is your passion. The Lab is where it becomes ready.”
