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
#include "MazurkaPlugin.h" // Mazurka plugin interface for Sonic Visualiser

Chris,
I can understand this and many thanks for your hard work.

Sorry to take so long about this -- I've been a bit swamped with a number of other things, one of which is an effort to make this sort of package update simpler! But that isn't in place yet... I'll try to get packages built and put up tomorrow.

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.

« on: December 11, 2009, 20:10:00 »
Hello Renato,
good to see another "ELF" person in this forum! I actually came across your site before and find it very interesting - thanks! I think what you are asking for is not possible with the current release of Sonic Visualizer, but maybe a future version or an update of one of the analysis VAMP plugins will provide it. ELF was actually what brought me to Sonic Visualizer as well - less from my own interest in amateur radio and astronomy but more from being one of those who can hear what the press often calls "the hum".
Here is another program that you might know: http://freenet-homepage.de/dl4yhf/spectra1.html
This program can do a lot of live DSP tasks - including various kinds of spectral analysis and signal decoding. Although it is a Windows program you can run it under Linux by using "wine". I even got it to work with Jack so I was able to use my Presonus Firebox with 96Khz sampling rate as input.

Host Forum: Sonic Visualiser / Re: Sonic Visulaiser Playback Problem in Ubuntu 9.10
« on: November 25, 2009, 19:34:33 »
I wonder if SV is trying to play back through ALSA while the sound output is locked by the pulseaudio sound server. I had lots of trouble with audio in the original 9.10 installation and decided to get rid of the main culprit - pulseaudio.
I know it is very difficult to get rid of pulseaudio in Karmic after some wise designers decided to remove the option to disable pulse. Switching from Gnome to KDE with its new phonon multimedia API solved all my audio problems.
Everything works fine (including Sonic Visualizer) after that.

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 / Re: SV 1.5 compilation does not recognize pulseaudio and portaudio
« on: May 06, 2009, 15:27:11 »If you are sure you have all the libraries and dev packages needed then the only thing to ask is what command did you use when you ran ./configure? If you could show us that, it would help to clarify what exactly has happpened. As well, the exact compiler error you are getting.
cheerrs,
davidf
Hi Davidf,
I am not aware of any "./configure" file. I just run "qmake" as described in the INSTALL file and then "make" to build the application from the Makefile. There are no visible compiler errors, the application builds fine. But it only lists "JACK audio connection kit" as the one and only choice in the preferences and no word of pulseaudio or portaudio in the "About" dialog.
thanks for your help, Mark

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.
libpulse / libpulse-dev 0.9.10
libportaudio / libportaudio-dev 18.1
thanks for any help.
