Share My Creation mp3 play speed changer and chord detector

Mp3 player with real-time play speed changing and chord detection functionality. It is a B4A version of the B4J one.
A music tool for amateur musician to follow the slow down playing to practice and catch the chord.
The chord detection algorithm is not perfect. Key detection seems fine.

  • + bpm detecton to improve chord detection
  • + other chord types
  • + change tune
  • + A-B segment loop play
