And you can download binary packages (Windows and Mac so far, Linux I'm working on at the mo) plus source from the page at https://code.soundsoftware.ac.uk/projects/sonic-visualiser/files

Plugin and Host Announcements / Sonic Annotator v1.4 now available

« on: March 18, 2016, 16:52:36 »

Sonic Annotator is a utility program for batch feature extraction from audio files.  It runs Vamp audio analysis plugins with specified parameters on audio files, and writes the result features in a selection of formats.

 http://vamp-plugins.org/sonic-annotator

Version 1.4 is now available. This is a bugfix release. Changes include:

Front-end changes:

 - Better error reporting, especially for invalid transform files
   and transform-not-found

 - Avoid crashing out when a single plugin (that is not being used)
   can't be loaded because of e.g. an undefined symbol

Bug fixes:

 - Fix (with test) horrible crash with --multiplex option

 - Fix erroneous quantization to 16 bits for coded file types of
   greater bit depth

 - Fix multiple outputs when requesting both summary and non-summary
   for the same output

It appears I did not announce the previous v1.3 release in this forum; for the record, the changes in v1.3 were as follows:

Back-end (feature writer) changes:

 - Add the --csv-digits, --lab-digits, and --jams-digits options to
   control the number of significant figures printed for feature values

 - Update the JAMS writer to JAMS 0.2.0 format

 - Show a more useful error message when user provides a filename
   instead of a transform id to the -d option (happened to me when
   cut-and-pasting command lines and I was quite baffled at first)

Plugin and Host Announcements / MATCH Vamp Plugin v1.0 released

« on: September 09, 2015, 13:06:26 »

Version 1.0 of the MATCH Vamp Plugin is now available:

  https://code.soundsoftware.ac.uk/projects/match-vamp

This is a Vamp plugin implementation of the MATCH audio alignment algorithm by Simon Dixon.

The plugin expects to receive two channels of input, which are assumed to represent two different monophonic recordings of the same underlying musical material for alignment.

This input format can be provided by, for example, Sonic Annotator's --multiplex option with two audio files.

This plugin is also used by Sonic Visualiser to provide its automatic alignment facility.

The v1.0 release is an aggregation of various performance and bug fix improvements since the last release, and it also adds a number of new parameters.

Plugin and Host Announcements / Silvet Note Transcription plugin v1.1 released

« on: September 09, 2015, 12:24:17 »

Silvet is a Vamp plugin for note transcription in polyphonic music.

   http://code.soundsoftware.ac.uk/projects/silvet

Silvet listens to audio recordings of music and tries to work out what notes are being played. It uses the method described in "A Shift-Invariant Latent Variable Model for Automatic Music Transcription" by Emmanouil Benetos and Simon Dixon (Computer Music Journal, 2012).

The plugin is provided with source code under the GNU General Public License, and with binaries for Windows, OS/X and Linux.

This new v1.1 release replaces the "draft" mode with a much faster "live" mode, adds a number of new outputs (note onsets, offsets, pitch activation matrix, chromagram), and adjusts some internal processing parameters to improve performance in test datasets.
