The latest version of aubio, 0.3.0, is now available. aubio is a library for audio labelling. The goal of this project is to provide automatic feature extraction algorithms to other audio software projects. Features include onset detection, beat tracking, and pitch detection. Functions can be used off-line in sound editors and software samplers, or online in audio effects and virtual instruments.
This release features several changes and includes a Puredata external, containing 5 objects:
* aubiopitch~ pitch tracking object, similar to fiddle~ and pick~ * aubioonset~ onset detection, similar to bonk~ * aubiotempo~ beat tracking * aubiotss~ transient / steady state separation (experimental) * aubioquiet~ simple silence detector
Not all aubio features are available from PD yet, but onset and pitch detection routines should be more robust than other existing externals. Other important changes include:
* new pitch detection method, yinfft * new beat tracking algorithm (improved from 0.2.0) * enhancements to the onset detection algorithms * improved aubiocut, can now slice at beats and silences * new aubiopitch python program to extract pitch tracks * plotting features for aubiocut and aubiopitch * python interface refactored * updated documentation
As usual, the source code can be found at http://aubio.piem.org/ , and Debian packages are available from http://piem.org/debian/ .
Feedback most appreciated!
