Host Forum: Sonic Visualiser / geting Sonic Visualiseer to use a specified codec

« on: June 11, 2009, 21:13:46 »

Sonic Visualiser (like most audio players in Ubuntu) does not know how to decode an Apple Lossless sound file. However, I have discovered that the alac-decoder (/usrle/bin/alac-decoder) is the codec for decoding apple lossless files. I have gotten VLC Player to use this codec, but do not know how to get Sonic Visualiser to use this codec to decode music files.

Is this possible? If so, how do I do it? I really do not want to compile Sonic Visualiser just to do this it would likely be easier but far more time consuming to decode the files on my much slower Mac lap top then transfer them to my eeepc.

Hopefullyhttp://www.sonicvisualiser.org this is a  trivial procvess (getting SV to use alac-decoder)

Host Forum: Sonic Visualiser / Is it posssible to make two (or more) specific layers active at once?

« on: May 01, 2009, 00:43:45 »

I have found it necessary to have an Time Instances layer and a Spectrograph layer active at the same time. Is there a way to select two specific layers and make them active at the same time? I  need to see the pitches and the time instances at the same time. It is the time instances I'm trying to edit, I just need the spectrograph data to make sure I'm at the right place in a large orchestral score.

thanks,

Host Forum: Sonic Visualiser / Screen corruption when using Mazurka Power curve plugins

« on: April 18, 2009, 08:45:36 »

Hello:

I've been getting horizontal lines and/or solid colour when when adding the Power Curve Mazurka plugin to a project. I had thought it was some strange curve happening until I hit play, then as the cursor passed over the  playback point the corruption disapeared and the real power curve was left behind.

However, it comes back each time a new page passes by and leaves as the cursor passes over it. If I switch away from the power curve tab, the corruption disappears, but will be back if I return  to that tab.

When I looked  at the command prompt I started SV from I found one error:

Code: [Select]

librdf fatal - Cannot add statement to model


I checked to find out what librdf was, and also if it was installed. Yes, librdf0 is present, librdf0-1.07-1

Any ideas on what this is all about?

I'm running an eee pc 1000 with 1 gig memory and Ubuntu "Intrepid Ibix"

cheers,

Getting and Using Vamp Plugins / Mazurka Plugin on eee pc running Ubuntu Linux

« on: March 26, 2009, 01:41:34 »

Hello:

I've installed Sonic Visualiser and  a number of other plugins. The extra plugins whose names begin with Mz show in SV, however, mazurka-plugins.so does not seem to be showing in SV at all. Specifically I was looking for the Power curve.

My machine runs an Intel Atom 1.6 Ghz with 1 Gig of memory on a solid state drive.

mazurak-plugins.so is installed (with all the other plugins) in /usr/lib/vamp/

Any suggestions as to why just the mazurka plugins are not showing up?

My guess is that they might not have been compiled for this particular x86 processor in mind.

cheers,
davidf
