Description
This app is automatic chord detector (chord finder) that uses the internal device microphone It also has some unique features as showing the music spectrum so you can actually see the notes in it. So ZAX can be used not only as a chord detector but also to show any instrument timbre. It shows all notes that are available as a frequencies in the sound. Basic tempo detection ( BPM detector) is also added to help you find the BPM for your song.
This particular version is still alpha and is equipped only with major and minor chords! This is a free version that is fully functional. The ZAX chord detector was not adjusted to find the chords for some specific instrument but is suitable for anything that makes sound :) I am still working hard on this app but I think that it can already be very useful.
ZAX Chord Detector features:
1. Chord guess (major minor only) 2. Music spectrum with notes 3. Pitch shift 4. Strongest note 5. Bass note 6. All notes detected in spectrum.
Works in the 70 - 450 Hz range. ZAX chord detector has the same simple user interface as my fine chromatic tuner app. It features not only chord detection but also spectrum analyzer. As polyphonic music analyzer ZAX Chord Detector can be used to help as music recogniser. It can help you to find chords of any song and to see why one instrument is sounding better than other. In terms of audio frequency analyzer it can show you the under and over tones. So you can see all the notes in spectral audio analyzer view.

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...

Really Sometimes cool it jumps between accurate reading gets most simple chords like c g e and d chords, so I take It's word on most others, for what its worth in future updates, pitch lab pro tuner app picks up and tells you any note played on one string, so it can be very integrative for chord reading tech thanks a lot :)

Save your bandwidth - this app doesn't even detect remotely correct BPM information of a click track/metronome in an acoustically treated room.

Not precise Learning the acoustic guitar by using this app set me back months. Does it just pick random chords to display?

MIGHT work if you've got a soundproof booth, but I couldn't get a consistent reading. It just jumped around flashing various wrong chords.

This app is retarded. It can't even get simple chords correct.
★☆☆☆☆MythicSlasher· Oct 13, 2019
This is a complete disaster of an application, the responce is so wack, when I played the G major, it shows the e min chord
