[PD-announce] [ANN] aubio 0.3.0

[Paul Brossier]

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!
