Key features include chord recognition (major and minor), music spectrum visualization, pitch shift, strongest note detection, bass note identification, and BPM (tempo) detection. Operating within the 70 - 450 Hz range, ZAX is designed to be versatile, suitable for any instrument or audio source. Currently in alpha, the free, fully functional extension serves as both a chord finder and a polyphonic music analyzer, making it ideal for musicians, composers, and audio enthusiasts aiming to understand and analyze music at a deeper level.

User Reviews

Reviews consistently praise real-time chord detection and memory aid for progressions, but note reliability issues: chords read incorrectly, BPM is unreliable, and fast/complex songs confuse the detector. Overall, it’s useful for learning and simple passages, but not dependable for professional use or rapid chord changes.

Pros

Real-time chord and note detection via the microphone, useful for musicians and composers.
Helps reconstruct chord progressions from old recordings and locate root bass notes quickly.
Effective for simple chords and slower tempos, providing clear feedback for basic progressions.

Cons

Inconsistent or incorrect chord detection, with chords reading wrongly or changing unpredictably.
Unreliable BPM readings, often not accurate or consistent with a metronome or click track.
Struggles with fast or complex progressions; performance is best on simple, slow passages and deteriorates with speed.

Recent reviews

Amazing app for music composer and artists.. i personally use it to decode the chords which are played.. i use a screen recorder which really help me to play those songs again and sound is appropriately for the song ... So kudos to the developer...

This is very effective for musicians.

I feel like it's made for single chords played at a time, or chords played at lower tempos. If a song is too fast, it tries to read it but then the chord switches and it gets confused.
