Guitar Music Analyzer Free is a music and radio app developed by Michael Dubbeldam. The app is available on Android platform and is completely free to use. The app is designed to take sound from the microphone input or music files (MP3 and Ogg Vorbis) on your device and display the frequency graph in real-time. This allows users to recognize the played notes and chords easily. The frequency graph is projected on the guitar for easy interpretation and the best matching common chords are displayed automatically.

In addition, the app allows users to pause and replay recordings and navigate through sound files. With Guitar Music Analyzer Free, transcribing guitar music becomes an easy visual task. However, it is important to note that this free version shows an ad banner and requires internet access permission. Users are encouraged to check out the paid version as well.
