Announcing the release of Sonic Visualiser 1.0pre3, a pre-release for the soon forthcoming Sonic Visualiser 1.0. http://www.sonicvisualiser.org/ Sonic Visualiser is an application for viewing and analysing the contents of music audio files. It contains advanced waveform and spectrogram viewers, as well as editors for many sorts of audio annotations. Besides visualisation, it can make and play selections based on the locations of automatically detected features, seamlessly loop playback of single or multiple noncontiguous regions, synthesise annotations for playback, and time-stretch playback while retaining display synchronisation. Sonic Visualiser also makes use of the Vamp plugin API, for plugins that extract descriptive or analytical data from audio. Vamp is an easy to use plugin API with a comprehensive and well-commented SDK, and is now frozen for the Vamp 1.0 release. Sonic Visualiser is Free Software distributed under the GNU General Public License. The 0.9 release is available now in source code form or as binaries for Linux, OS/X, and Windows.
