Favorites (0)

For composers, practicing musicians and music aficionados everywhere, this application provides acoustic analysis information on a multitrack jazz recording.

Using user supplied tracks and an iPad application, Echonest acoustic features are computed for each instrument voice in the composition. The data is then plotted for visualization of the musical and acoustic properties during playback.

Currently, the following approach is taken:
-Onset and duration analysis for each track
-Pitch estimation via chroma
-Showing the pitch (in one octave) on a piano roll
-Updating the roll based on the current section of the composition

Coming soon:
-rhythmic pattern analysis via drum onsets and loudness values.
