Getting and Using Vamp Plugins / Re: Sonic Visualizer cant find the vamp plugins
« Last post by Orville on November 19, 2015, 19:31:16 »
I put the vamp plugins folder inside c/programme but I still can't see the plugin.
I've updated the Linux packages -- the binaries within them are the same, but I hope these two problems should be fixed now. I've updated the version number, and the dependency is now on jackd rather than libjack<N>.

(I realised that removing the jack dependency from the package would require rebuilding the binary using an alternative linkage for JACK, and I'm quite keen not to alter the binary for things that should be pure packaging issues. Having a dependency on jackd seems quite common for other JACK applications, but I'm not quite sure what the "proper" way to work around this versioning problem is -- let me know if this isn't working for you.)
Mm, there probably shouldn't be a dependency on JACK at all, since it does work without it.

Thanks for the report, I'll try to look at these things on Monday (probably won't get time before then I'm afraid).

There seems to be something wrong with the 64bit Ubuntu package (trying to install on Ubuntu 15.04).
First problem is that the package identifies itself as version 2.4cc-1, not 2.5
Second problem is the dependency to libjack0:amd64 what is a jack1 library. This completely breaks systems using jack2:

sudo dpkg -i sonic-visualiser_2.5cc1-1_amd64.deb
Selecting previously unselected package sonic-visualiser.
(Reading database ... 423781 files and directories currently installed.)
Preparing to unpack sonic-visualiser_2.5cc1-1_amd64.deb ...
Unpacking sonic-visualiser (2.4cc-1) ...
dpkg: dependency problems prevent configuration of sonic-visualiser:
 sonic-visualiser depends on libjack0; however:
  Package libjack0:amd64 is not installed.

Sonic Visualiser is an application for inspecting and analysing the
contents of music audio files. It combines powerful waveform and
spectral visualisation tools with automated feature extraction plugins
and annotation capabilities.

Version 2.5 of Sonic Visualiser is now available. This is primarily
a bugfix release, though it also adds a potentially-useful "unit
conversion" dialog.

For more information, please read the change log at:

Host Forum: Sonic Visualiser / exporting audio with tempo change
« Last post by samuelzen on October 12, 2015, 18:02:24 »
Is it possible to export the audio at the tempo that I've adjusted (i.e., slowed) with the "nob" in the lower right of the SV gui? When I export the audio file in Sonic Visualiser, the file does not inherent the tempo change. I know I can alter the tempo of the file in Audacity and it export it. However, I prefer the tempo control in Sonic Visualiser. It seems to be produce less distortion when slowing a track down. Plus, I can more easily fine tune the tempo since I can do it in real-time.

Plugin and Host Announcements / Sonic Annotator v1.2 now available
« Last post by cannam on September 09, 2015, 14:10:43 »
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.

Version 1.2 is now available. This is a bugfix and minor feature release. Changes include:

Front-end changes:

 - Add the --segments-from option, providing the ability to read segment boundaries from a file

Back-end (feature writer) changes:

 - Rename the JSON feature writer to JAMS. There may be other JSON formats supported in future

Bug fixes:

 - Fix invalid JSON written by JAMS feature writer for dense features.
 - Fix invalid UTF-8 output from RDF feature writer when processing MP3 files having ID3 tags in non-ASCII, non-UTF8 encodings

Plugin and Host Announcements / MATCH Vamp Plugin v1.0 released
« Last post by cannam on September 09, 2015, 13:06:26 »
Version 1.0 of the MATCH Vamp Plugin is now available:

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.

NNLS Chroma/Chordino is an open source Vamp plugin library for harmony and chord extraction with some features aimed at amateur musicians, and some at music information retrieval researchers.
