What's new in v1.1.0

Changed app name. Major speed improvement loading mp3 and ogg files using native code.

Description

From the listing uploaded by “appupdater”.

The analyzer takes sound from the microphone input or music files on your device (MP3 and Ogg Vorbis). It shows the frequency graph in real-time, from which you can recognize the played notes. The frequency graph is projected on the guitar for easy interpretation. The best matching common chords are displayed automatically. You can pause and replay recordings and navigate through sound files. With Guitar Music Analyzer, transscribing guitar music becomes an easy visual task. This free version shows an ad banner and requires internet access permission. Please check out the paid version as well.
