Greetings,

First, thanks for making such nice tool for researching with sound and sound data!

I have a concatenative synthesizer, and have been exporting overlays (*.svl) with intermediate information from the synthesis algorithms in Matlab. The overlays are for viewing with the synthesized sound, for debugging and visualization purposes.

The data itself is sparse (just a few non-zero values to display for each analysis frame) and graphical (there are connections or non-connections or special connections between nodes in subsequent analysis frame). It looks sort of like this (out.svgz). The timeline in the displayed file is given on the right, and the bubbles are synthesis frames denoting (time in source file, transposition in semitones, and gain).

What I’ve done so far:

For showing where tracks start and end, I’m using the “regions” display layer. This works fine and will not be discussed. (regions.gif)
For showing details of individual synthesis atoms, I’m attempting to use “time values” layers. This has limited success and is discussed onward (tracks.gif).

Within a display layer, connections between time values can set to be connected or disconnected for the entire layer by setting plotStyle="0” (disconnected) or plotStyle="2" (connected). For my application, this necessitates each connected track being in its own layer. In my application, there are hundreds of these per input file.

The slight hindrances are:

1. If you manage to load the input file (svl in instants1.zip), you end up something that visualizes well (the various tracks are plotted correctly). But when you hover to see detail with the Navigate hand, it won’t be accessible unless it is the selected layer, and you have no good way to find and go to the correct layer.

If it were possible to pick points outside of the current layer with Navigate, this might be fixed.

(Update: this turns out to not be a big deal. "Time values" points are limited to two Attributes, so there's nothing in the Detail view that is not already showing when you fully zoom in on a point. Unless you need to edit the time values, you have no need to select the layer.)

If you need to select the layer, I would recommend using the Layer Summary to find the correct layer (using the Name). Optimally, double clicking the layer in Layer Summary would change to the selected layer. (double clicking doesn't seem to be currently linked to anything.) layerSummary2.png

2. When there are too many layers (svl in instants2.zip), Sonic Visualizer crashes hangs for a long time, but seems to be completely stable once everything is loaded. In addition, if you close the program or even delete a single layer (Ctrl-D) it also hangs, it eventually returns from the latter but the former seems to take on the same order, minutes, as it takes to load the overlay file.

This could be related to the way SV-XML allocates new layers on demand. Perhaps there is a way to optimizing loading of large overlay files, or perhaps some feedback to the UI (even a progress bar) would improve this process for the user.

In the Debug build, I kept getting the message "WARNING: SV-XML: Layer id x in view section has not been defined -- defining it here", but I couldn't find an obvious way to fix it.

Note: file attachments don't seem to be working on the forum, I got some kind of error about trouble accessing upload directory.

Getting and Using Vamp Plugins / Re: Installation of Vamp plug-ins
« Last post by AncientMind on August 01, 2013, 16:38:53 »
Re: Installation of Vamp plug-ins

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.

Perhaps...
But my Win7/64 gives me msvcp100.dll - errors resulting in sonic visualizer doesn't recognize any plugin (no matter where I place it/them). I placed \Vamp Plugins in c:\Programme (86), in \sonic visualizer, I used sonic visualizer as zipped executable and installed - in every possible combination. Always msvcp100.dll missing - but this file in fact isn't missing and works well for other applications  :o >:( . Any idea???

Host Forum: Sonic Visualiser / Sonic Visualiser language and key shortcuts
« Last post by vmach on August 01, 2013, 08:34:39 »
Hello, I'm new to Sonic Visualizer. I have a Windows binary version on my W7 in Czech. After instalation of Sonic Visualizer, the software is automatically translated to Czech (very poor) but I want to have it in English. How can I change it?

Next problem is that there is no "spacebar" key shortcut for playing and also it is not possible to set it up.

Could you, please, help me with these problems?
THX!

Plugin Development / Vamp Test Plugin v1.0 released
« Last post by cannam 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.

I tried to install Vamp Plugins to Windows XP. I tried all hints in the Internet without success. Finally i succeeded: c:\Vamp Plugins is my folder to install VP there. I am very happy after 3 days of work to install.
