Getting and Using Vamp Plugins / Detection function for aubio onset detection
« Last post by manojpamk on November 12, 2014, 18:39:17 »
Hi all

I have been using the aubio onset detection plugin for quite some time now. (source : https://code.soundsoftware.ac.uk/projects/vamp-aubio-plugins/files ). The plugins output the onset time for different algorithms. I would like to know where can I find the plugins that would output the "detection functions". The source code for the plugins are preferred.

I discovered the 32-bit equivalent library, but cannot locate the source..  :-\

EDIT:
The source for the original plugins (without the detection function output) is available here : https://github.com/piem/vamp-aubio-plugins
I have raised an issue about the above problem : https://github.com/piem/vamp-aubio-plugins/issues/1

Host Forum: Sonic Visualiser / Possible dependancy problems in Windows?
« Last post by Notis Funn on November 03, 2014, 09:40:46 »
I have Sonic installed on both XP and Windows 7. I receive an error message in both cases upon exiting the program. Windows XP will actually notify me, in the details, that the problem has something to do with libpthreads. Looking this up on the internet I found pthreads had to do with a Posix system, and Windows, since XP, has moved on to a Unix based system. I was wondering if there is some dependency I'm missing such as a C++ library, or Net Framework 1.1. I had looked on this forum at some of the crash reports but nothing seemed to fit my case, but I hope some of this information will help resolve some of these issues. The Sonic Visualizer is operable on my systems so that I can use it, but I guess I am just a perfectionist after all.

Plugin Development / qm-dsp and qm-vamp-plugins for Fedora
« Last post by valtri on November 01, 2014, 13:52:08 »
Hello,

I'm packaging qm-dsp and qm-vamp-plugins for Fedora and EPEL (the review requests are here: https://bugzilla.redhat.com/show_bug.cgi?id=1060519, https://bugzilla.redhat.com/show_bug.cgi?id=1060520).

You can consider applying these patches used for Fedora (ported to the latest development version):
  http://scientific.zcu.cz/fedora/REVIEWS/qm-dsp-install.patch
  http://scientific.zcu.cz/fedora/REVIEWS/qm-vamp-plugins-flags.patch

Also license texts in qm-dsp/qm-vamp-plugins can be updated - the bearded guy changed the address. The latest GPL 2.0 license text is here: http://www.gnu.org/licenses/gpl-2.0.txt.

Cheers,

Plugin Development / Vamp Plugins and Audacity
« Last post by cpsmusic on October 29, 2014, 22:54:54 »
Hi,

I work as an audio editor and use Audacity quite a bit in my work. I also have a background in C/C++ software development.

I'd like to try developing some plugins using Vamp however I'm a bit unclear as to how Vamp interacts with Audacity in displaying plugin output. Is this explained anywhere?

Cheers,

Chris

Plugin and Host Announcements / Vamp Tempogram Plugin
« Last post by cannam on October 16, 2014, 14:21:35 »
Version 1.0 of a new Tempogram plugin is now available.

This is an implementation of the tempogram and cyclic tempogram
features described in Grosche, Müller, and Kurth 2010, providing a
robust mid-level representation that encodes local tempo information.

The plugin was written by Carl Bussey at Queen Mary University of
London, and is published under the GNU General Public License.

See https://code.soundsoftware.ac.uk/projects/vamp-tempogram
for downloads and more information.

Plugin and Host Announcements / Sonic Annotator v1.1 now available
« Last post by cannam on October 16, 2014, 12:44:45 »
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 1.1 is now available. This is a major feature release. Changes include:

Front-end changes:

 - Add support for the start time and duration properties of a transform, applying a plugin to only a range of the input audio
 - Reduce the internal processing blocksize from 16384 to 1024 samples to reduce extent of time rounding at end of file or range
 - Add --multiplex option to compose multiple audio files into a single multi-channel stream with one input file per channel
 - Add --normalise to request each audio file be normalised to 1.0 max
 - Add support for the plugin_version property of a transform, causing Sonic Annotator to refuse to run with the wrong version of a plugin
 - Add --minversion option to permit scripts to check that the version of Sonic Annotator is as they expect
 - Add new housekeeping options to list the available feature writers and supported audio file formats
 - Pull out the feature-writer-specific help text into separate help options (-h <writertype>) as the help was getting too long

Back-end (feature writer) changes:

 - Add --csv-omit-filename, --csv-end-times, and --csv-fill-ends options to the CSV feature writer to adjust various aspects of its output
 - Add "json" feature writer, exporting to JAMS (JSON Annotated Music Specification) format. This writer is provisional and is expected to change in future releases to comply more effectively with the specification
 - Add "midi" feature writer, exporting to MIDI files
 - Add "lab" feature writer, exporting to tab-separated label files. (This is equivalent to using the CSV writer with a tab separator and the new --csv-omit-filename and --csv-end-times options, but it's simpler to use if .lab is what you want)

Bug fixes:

 - Fix the former habit of forging ahead even if not all transform files could be found or parsed (this may have been intentional behaviour but it is confusing more than it is useful)
 - Fix failure to support --summary-only flag when reading transforms with summaries from a transform file

Thank you for your quick response and for your help. I guess I'll change some settings in Panda.

I've sent a note to the Panda false-positives email address asking if they can look into this.

I have also re-checked with Avast, and double-checked the actual file that is provided for download at the Sonic Visualiser download page, and have continued to find nothing wrong. Builds are carried out on a virtual machine dedicated to the task, which I would have expected to be clean.

I then tested with Panda to see whether I got the same result as you, and I found that I did -- it gives me the same report for the Sonic Visualiser 2.4.1 executable. I believe it is simply mistaken, but it's not clear to me how I could prove that.

Hi -- That looks alarming.

I have just re-checked the binaries and the machine image on which the application was built and packaged using Microsoft's malware scanner and found no sign of anything wrong.

I'm fairly sure this must mean the alert from Panda is a false positive. The Panda database gives essentially no information about what this trojan is thought to consist of, so it's quite hard to check, but it does say it was added to the database five years ago which suggests that any other malware scanner should pick it up as well if it is genuine.

I will see whether I can learn anything else about what is going on here.

Thanks,


Chris
