Find the key. Tune the note. Keep the result. PulseKey brings musical key analysis and instrument tuning together on your iPhone. Listen through the microphone or import an audio file. Audio analysis happens on your device, with no account required. KEY ANALYSIS Estimate major and minor keys from music around you or imported audio. See the relative key, Camelot and Open Key notation, scale notes, diatonic chords, and compatible mixing keys. A harmonic profile shows the pitch classes contributing to the result. INSTRUMENT TUNER See note, frequency, and cents while you tune. Use automatic targeting or lock a target note. Choose an instrument preset or create a custom tuning. Adjust the A4 reference from 415 to 466 Hz, play a reference tone, and follow the pitch trace. AUDIO WORKSPACE Import audio, analyze a selected region, and inspect estimated keys across six-second windows. Loop a section while working through it. YOUR LOCAL LIBRARY Save measurements with titles and notes. Keep custom tunings ready for your next session. Saved analyses retain results, not source audio. EXPERIMENTAL DRUM TOOLS Capture sustained drum resonances after a strike, hold a reference, and compare measurements across lugs. Drum readings are experimental and may reflect an overtone rather than the fundamental. DESIGNED FOR FOCUSED LISTENING No advertising, tracking, or account setup. Microphone audio and imported files are not uploaded by PulseKey. Key and pitch readings are estimates. Results depend on the sound, microphone, room noise, and instrument. For tuning, play one clear note at a time. Complex music and inharmonic percussion can produce ambiguous results.
