Plugin Development / Re: newbie erro

« on: February 07, 2014, 16:47:45 »

Hi there --

My wild guess is that this is a problem with the selection of compiler SDK (i.e. which set of OS/X platform libraries the compiler tries to build for).

Try getting the compiler to switch back to its default settings (to compile for the current platform only) by removing the "-mmacosx-version-min=10.5 -arch i386 -arch x86_64" flags from the Makefile you're using, and see if that helps.

Host Forum: Sonic Visualiser / Re: Can't open .dmg of AV 2.2

« on: November 14, 2013, 17:16:25 »

Hi again -- we've made some configuration changes on the server, so if you -- or any other reader -- have been having problems with this, can you try again and let me know whether it works any better now?

As another alternative, try changing the URL scheme for the file download URL (the code.soundsoftware one) from http:// to https:// and again let me know if it helps.

Thanks...

Plugin Development / Re: Mobile Development - armv7 / iOS Platforms

« on: November 14, 2013, 14:37:42 »

Hi there -- I'm afraid I know very little about how to compile anything for iOS, but I should point out a significant problem with what you're trying to do:

Although the Vamp plugin SDK is indeed BSD-style licenced, so that you can write both plugins and hosts under any licence you wish, the QM Vamp Plugins and qm-dsp libraries are not. They are instead under the GPL, meaning you cannot use them in App Store code at all unless you have a separate commercial licence (available from QM).

I'm sorry to bring this disappointing news...

Another user reported this to me recently, but I think it turned out to be an incomplete download. Possibly the server is timing out too easily? Can you check the file size and/or md5sum for the file against those listed on the download page, and perhaps try again?

Host Development / Vamp Test Plugin v1.0 released

« on: May 16, 2013, 16:29:26 »

Version 1.0 of the Vamp Test Plugin is now available.

This, the world's least interesting Vamp plugin, is the equivalent of a TV test signal: it produces a set of very simple static outputs intended to help the authors of Vamp hosts check that they are handling plugin output sample types correctly.

See https://code.soundsoftware.ac.uk/projects/vamp-test-plugin for more information.

If you are the author of a Vamp host, you might find it useful.

Plugin and Host Announcements / Sonic Annotator v1.0 now available

« on: May 10, 2013, 08:49:35 »

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, in particular as RDF using the Audio Features
and Event ontologies, or as simple CSV files.

Version 1.0 is now available. This is a bugfix release.
For more details, see the changelog at

http://code.soundsoftware.ac.uk/projects/sonic-annotator/repository/entry/CHANGELOG

Plugin Development / Vamp plugin SDK v2.5 now available

« on: May 10, 2013, 08:43:43 »

Version 2.5 of the Vamp plugin SDK is now available.

   http://www.vamp-plugins.org/

Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++.  Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation.  It is supported across Linux, OS/X, and Windows.

A documentation guide to writing plugins using the Vamp SDK can be found at http://www.vamp-plugins.org/guide.pdf.

Version 2.5 is a bugfix release. For more details, see the changelog at

http://code.soundsoftware.ac.uk/projects/vamp-plugin-sdk/repository/entry/CHANGELOG

The most significant fix in this release is in the host SDK, and affects the handling of output timestamps in the (little used) FixedSampleRate output type.

Plugin Development / Re: Plugin DLL not recognised by SV on windows

« on: May 02, 2013, 14:15:01 »

Hi Justin -- is it possible it depends on a version of e.g. the VC++ runtime which is not installed on these machines?

Can you try the DLL in Dependency Walker (http://www.dependencywalker.com/) on one of the offending machines?

Host Forum: Sonic Visualiser / Looking at the Sonic Visualiser user survey

« on: April 26, 2013, 16:48:23 »

I just posted this analysis of some of the basic numerical data from the Sonic Visualiser user survey (the one that SV asks whether you'd like to complete, after you have run the program a few times -- you may be familiar with it):

http://thebreakfastpost.com/2013/04/26/looking-at-the-sonic-visualiser-user-survey-part-1/

The survey's been running for some time, and I've looked at responses in the past but have never previously published any data from it. Might be of interest to some!

Host Forum: Sonic Visualiser / Re: Decimation in spectrograms ?

« on: April 26, 2013, 16:46:17 »

SV doesn't actually have any means of downsampling or decimating audio on request, I'm afraid -- it would be necessary to downsample the file outside of SV before loading it.

It would be possible for a Vamp plugin to offer this as an option, but I'm not sure whether any existing one does.

Getting and Using Vamp Plugins / Re: compiling mazurka plugins - where can I find "MazurkaPlugin.h" ?

« on: March 14, 2013, 16:07:41 »

Hi Mark -- it looks like you can find all the .h files http://sv.mazurka.org.uk/include/ (go there in a browser, and you'll see a file listing) and the .cpp files at http://sv.mazurka.org.uk/src/. Might not be the most elegant way to download, but it does seem to be possible.

Getting and Using Vamp Plugins / Re: Installation of Vamp plug-ins

« on: March 01, 2013, 19:01:29 »

Hi -- all the Windows builds of plugins linked at http://vamp-plugins.org/download.html are 32-bit versions, but they will work fine in a 64-bit version of Windows so long as the host is also 32-bit.

(64-bit Windows is happy to run 32-bit binaries, but the host and plugin must match -- in this case both must be 32-bit.)

The installation folders are listed at the bottom of http://vamp-plugins.org/download.html. Note that on a 64-bit Windows, you must install 32-bit plugins in

Code: [Select]

C:\Program Files (x86)\Vamp Plugins
or your language's localised equivalent -- with the (x86) suffix -- and not just in Program Files.
