Turn your raw audio tracks into clean, synchronized musical insights in 3 effortless steps.
Paste YouTube Link or Upload Audio
Paste any YouTube video URL or select your own MP3, WAV, M4A, or FLAC track from your computer or mobile storage. Zero manual setup needed.
Instant AI Harmonic Detection
Our neural engine extracts the root key, tempo (BPM), compound time signature (4/4, 3/4, 6/8), and synchronized chord progression within seconds.
Export MIDI or Jam Offline
Drag multi-track MIDI stems into FL Studio or Cubase, or play along offline with the beat metronome, pitch transposer, and PDF lead sheets!
Engineered for Producers & Musicians
Every feature has been meticulously crafted to bridge raw sound into actionable music theory.
Precision Harmonic Recognition
Identifies major, minor, 7th, maj7, m7, suspended, diminished, and extended jazz slash chords directly from audio recordings.
Beat-Synced Metronome
Practice and jam with glowing chord tiles and bouncing ball beat markers scrolling in exact synchronization with playback.
1-Click DAW MIDI Stems
Export multi-track MIDI files directly into FL Studio, Cubase, Logic Pro, Studio One, or Ableton to arrange your own productions.
100% Airplane Mode Ready
The Free Android APK executes on-device DSP models with zero data usage. Perfect for stages, sound checks, and outdoor rehearsals.
Compound Meter (6/8 & 3/4)
