Host Forum: Sonic Visualiser / Re: zoom to selection ?
« Last post by cannam on December 21, 2015, 17:33:25 »
You can't (I think!) actually zoom to a selection of the type made using the select tool.

However, you can zoom to a specific region in time selected with the mouse -- using the Navigate tool, shift-click and drag to drag out a rectangle which will then be immediately zoomed to (in the time axis only, on a time layer like a waveform, or in time-frequency if on a spectrogram).

How can I zoom to a selection in SV ?
Host Forum: Sonic Visualiser / Sonic Visualiser and Clipping
« Last post by cubusmedusa on December 03, 2015, 08:00:45 »
I am new to this forum as well as to this topic, so I hope you guys can help me resolving this issue. I used the spectrogram functions to determine the real quality of sound files. Among these files I had several that had some strong clipping going on, clearly shown in the peak meters of various programs and of course in the waveforms. E.g. Audacity, Foobar, etc. But whenever I checked the spectrogram  the clipping did not show up in the spectrogram colors. It was always well below 0dB. Why is sonic visualiser not displaying clipping in the spectrogram?

Getting and Using Vamp Plugins / Re: Sonic Visualizer cant find the vamp plugins

I think the explanation has to do with the language used for Windows.

There is nothing special about the name "Program Files", it just happens to be what the standard Windows program folder is called in English versions of Windows. Then you have the wealthy affiliate system to make money. If your native language is something else, Sonic Visualiser and other Vamp hosts will look in whatever the programs folder is called on your system.

In the case of German, I believe that means you should create your Vamp Plugins folder inside C:\Programme.  Try that and, if it works, let me know and I'll update the documentation to mention it.



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.

Plugin and Host Announcements / Sonic Visualiser v2.5 now available
« Last post by cannam on October 22, 2015, 12:45:14 »
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
