Host Forum: Sonic Visualiser / sonic-visualiser_2.5cc1-1_amd64.deb = dependency and package problems

« on: November 12, 2015, 12:39:32 »

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.

Host Forum: Sonic Visualiser / Decimation in spectrograms ?

« on: March 30, 2013, 18:03:59 »

Is it possible to use decimation in spectrograms and how can this be done ? Decimation uses only every n-th. sample for the spectrum analysis. This highly increases resolution in the lower frequency bands while lowering the highest frequency in the spectrogram. For example decimating a recording with 48Khz samplererate by 256 would give you a maximum frequency of about 97Hz with possible resolutions of less than 1 Hz.

Getting and Using Vamp Plugins / compiling mazurka plugins - where can I find "MazurkaPlugin.h" ?

« on: March 07, 2013, 11:10:36 »

I am trying to compile some Mazurka plugins to get them running on my 64bit Linux machine. The problem is that although sources are available for download on the Mazurka site, I could not find "MazurkaPlugin.h" what is referenced in all mazurka header files:
#include "MazurkaPlugin.h"  // Mazurka plugin interface for Sonic Visualiser
any help is appreciated, Mark

Host Forum: Sonic Visualiser / Linux build of 1.7.2 ?

« on: May 31, 2010, 12:55:41 »

Does anyone know when a debian package of version 1.7.2 will be available, or if there are any problems with package maintenance etc. ? I just notice that the different platform releases for version 1.7.1 where released at the same date while it still sais "coming soon" for Linux and Solaris for 1.7.2. Thanks for all the work that is put into the development of Sonic Visualizer.

Host Forum: Sonic Visualiser / Spectrogram display based on musical notation instead of Hz ?

« on: January 28, 2010, 13:41:40 »

Does SV provide an option to display a spectrogram to use musical notation instead of frequencies in Hz ? I would like to translate some music into midi, I do not have the perfect musical ears (yet) and the various vamp-plugins and other software pieces that try to convert recorded audio into midi are very tricky.
Technically  I think this should be possible with a scale based on 440 Hz concert pitch.

Host Forum: Sonic Visualiser / Can I use an external MIDI synthesizer for playback ?

« on: November 25, 2009, 19:27:38 »

Is it possible to route the MIDI output to use an external (software) synthesizer like fluidsynth instead of the built-in DSSI MIDI playback ? I could not find such an option and neither ALSAs aconnectgui nor Jack show a routable MIDI output from SV. I am using Sonic Visualizer on Ubuntu Linux 9.10 "Karmic".

Host Forum: Sonic Visualiser / SV 1.5 compilation does not recognize pulseaudio and portaudio

« on: April 21, 2009, 10:37:03 »

I am trying to build version 1.5 from source. The compilation works fine, but the resulting Sonic-Visualizer build has only Jack support. Both pulseaudio and portaudio support is missing although the libraries and the headers are installed. The system is Ubuntu 8.04 "Hardy Heron" with the following libraries:
libpulse / libpulse-dev 0.9.10
libportaudio / libportaudio-dev 18.1
thanks for any help.
