Host Forum: Sonic Visualiser / Re: trojan in the exe-file
« Last post by cannam on October 09, 2014, 13:15:47 »
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

Host Forum: Sonic Visualiser / trojan in the exe-file
« Last post by Sound analyser on October 09, 2014, 12:50:21 »
My Panda virus software detects the trojan Trj/Krap.W when I finish my installation of Sonic Visualiser (Windows) and automatically deletes the exe-file. Can anyone explain this?

Best regards

Here's the second beta release of the forthcoming v2.4. This might also be the final beta.

Once again, if you're interested in Sonic Visualiser but you're not using it for anything critical, I'd be grateful if you could download and test it! I only got a small amount of feedback from the first beta, but that was enough to allow me to fix two or three quite serious problems with it, so your reports are welcomed.

Currently there are pre-built packages for Windows and OS/X plus a source code package.

Download links are:

Windows installer
http://code.soundsoftware.ac.uk/attachments/download/1168/sonic-visualiser-2.3.91.msi

OS/X disk image
http://code.soundsoftware.ac.uk/attachments/download/1169/Sonic%20Visualiser-2.3.91.dmg

Source code
http://code.soundsoftware.ac.uk/attachments/download/1170/sonic-visualiser-2.4beta2.tar.gz

(Note as before, it may identify as either v2.3.91 or v2.4beta2 -- they are the same thing)

Host Forum: Sonic Visualiser / MIDI file
« Last post by derf on August 26, 2014, 06:17:45 »
Hello.
I use the plug-in Aubio Pitch detector. I export MIDI files with the command "Export annotations layer..." (*.mid). There is a problem. I cannot open these files in the software SEQ24. Do you know why we cannot make it?
Thank you for your answer.

By using Syntfont I realized that these MIDI files have no METAEVENT. For example: I read "METAEAVENT cue point =???"
Thus, my question is now more precise. Is it necessary to add METAEVENT to MIDI files created by Sonic Visualiser?

I should have linked to the changelog:

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

Besides the feature changes, this is the first release to be built using Qt5 (rather than Qt4) on OS/X.

(The previous release had already switched to Qt5 on Windows but there were problems with it on OS/X that have only just been dealt with.)

Hi all -- I've just packaged up a beta-test release of the next version of Sonic Visualiser (which will be v2.4).

If you are interested in Sonic Visualiser but you're not using it for anything critical (so you don't care if it breaks) -- and if you're happy to provide feedback about any problems you have -- then I'd be grateful if you could download and test it!

Currently there are pre-built packages for Windows and OS/X plus a source code package.

Download links are:

Windows installer
http://code.soundsoftware.ac.uk/attachments/download/1144/sonic-visualiser-2.3.90.msi

OS/X disk image
http://code.soundsoftware.ac.uk/attachments/download/1143/Sonic%20Visualiser-2.3.90.dmg

Source code
http://code.soundsoftware.ac.uk/attachments/download/1145/sonic-visualiser-2.4beta1.tar.gz

(Note, it may identify as either v2.3.90 or v2.4beta1 -- they are the same thing)

The actual 2.4 release is likely to follow some time in September.

Plugin and Host Announcements / Silvet Note Transcription plugin v1.0 released
« Last post by cannam on August 09, 2014, 13:38:21 »
Silvet is a Vamp plugin for note transcription in polyphonic music.

   http://code.soundsoftware.ac.uk/projects/silvet

Silvet listens to audio recordings of music and tries to work out what notes are being played. It uses the method described in "A Shift-Invariant Latent Variable Model for Automatic Music Transcription" by Emmanouil Benetos and Simon Dixon (Computer Music Journal, 2012).

The plugin is provided with source code under the GNU General Public License, and with binaries for Windows, OS/X and Linux.

How good is it?

Silvet performs well for some recordings, but the range of music that works well is quite limited at this stage. Generally it works best with piano or acoustic instruments in solo or small-ensemble music.

Silvet does not transcribe percussion and has a limited range of instrument support. It does not technically support vocals, although it will sometimes transcribe them anyway.

You can usually expect the output to be reasonably informative and to bear some audible relationship to the actual notes, but you shouldn't expect to get something that can be directly converted to a readable score. For much rock/pop music in particular the results will be, at best, recognisable.

To summarise: try it and see.
