Dear all,


Sonic Visualiser is a good and free program for viewing and analysing the contents of audio files, developed at the Centre for Digital Music, Queen Mary University of London:


It can be downloaded from


  * Works on Windows, Mac and Linux

  * Free and open-source (GPL)

  * User-friendly visualisation

  * Many feature-extraction plugins (see <>) including pitch tracking, MFCCs, Constant-Q spectra, adaptive spectrogram, spectral statistics, automatic segmentation

  * Extensible - you can add new analyses written in Python or C++

  * Data export/import: text, CSV, RDF, XML


People from the Centre for Digital Music are also currently working on a birdsong-segmenting plugin (for automatic labeling) that should be available in the next months.
