Download MusicBricks – Demo Software
As part of the MusicBricks project, Fraunhofer IDMT provides several technologies for music analysis. In particular, a commandline tool for extracting the main (predominant) melody, the bass line, the chord progression, the key, and the beat grid from audio files is provided. Second, a library for real-time monophonic and polyphonic pitch detection is included, which can deal with various types of musical instruments and sung vocals. We also provide the commandline tool "Goatify" for replacing the main melody in any song with any user-selected sample like a goat scream. The sample will be pitched according to the main melody and various types of samples can be used like instrument notes or animal sounds. Furthermore, we make our time stretching and pitching shifting library available which allows pitch shifting of audio samples in real time without changing the tempo and vice versa.
