As a scientist, I have been using Sonic Visualizer for many years in time segmentation domain. I work on microtiming and use a lot onset detectors. This tool is very useful for my researches. :)

Recently, while I still can hear without any problem the musical excerpts that I analyse, it became impossible to hear any sound from "libray sample player" plugin (whatever "tap", "click", "beep" selected). I cannot work without this fantastic feature (developed by Chris Cannam) which allows me to verify (as a musician) the relevance of the detected onsets.

I use Sonic Visualizer v 2.2 and v 2.1 on two different computers, each one with Windows XP. Same problem occurs. :-\

Many thanks by advance  for your help,

Best regards
Hi all,

I don't understand. I have been using Sonic Visualiser for several years without any problem for microtiming analysis (scientific researches).

I can hear the audio of wav source, but, whatever onset detector I try (or any plugin doing another kind of segmentation), it's now impossible to ear the "tics" (result of segmentation), a very convenient feature to verify, as a musician, the relevance of the analysis. I tested v 2.2 on a computer and v 2.3 on another one.
Very strange, because the options related to the tics are very simple.

Anybody could help me ?

Many thanks by advance.
Getting and Using Vamp Plugins / detecting onsets by spectra

I have an audio file consisting of alternating slap and open tones performed on a conga drum. Is there a plugin (or method with existing plugins) that would allow me to detect just the slap or just the open tones? I'm working in Sonic Visualizer.
Thank You!

I am aware of the fact that Sonic Visualiser is not a real-time sound analyzer, but I wonder if there is a way to analyze Csound f tables with it, perhaps with a plug-in.

Many thanks.

Hi there -- I'm not sure about the details of this file layout, but SV definitely should not crash when trying to import it!

Can you attach here, or send to me by email, an example annotation file? (I'm cannam at

I would like to use plugins in Sonic Visualiser and have installed some plugins to /usr/local/lib/vamp but they are not being detected by Sonic Visualiser. At least, they are not showing up under Transform -> Find a transform.
Any pointers would be appreciated.
Many thanks,
