Description:

Impulse is a bit of eye-candy for your desktop. It is a widget that displays a graphical spectrum analyzer on your gnome desktop. It is written in c and python and uses GTK and cairo graphics to generate the animation. the impulse library creates a pulse audio connection context that reads the output stream from pulseaudio in a thread natively which can then be read from python. You can specify impulse to either output the raw stream or output the fft of the raw stream.


Requires:
screenlets 1.2
libfftw3-3
libpulse0


Install:
1) Download and extract Impulse.tar.bz2
2) mv Impulse ~/.screenlets/
then open up the screenlets manager and start Impulse or open screenlets manager and click Install, navigate to the Impulse.tar.bz2 archive and click ok.

 Impulse stopped working

Few days ago Impulse stopped working.
It shows up, but seems like it can't hear my music anymore.
I use Ubuntu 10.10, have all dependencies needed, it worked well. I'm using the latest screenlets version of Impulse.
How can I find out where is the problem, give me some directions please?

A quick fix is to run the command:
$ pacmd set-source-mute 0 0

The first '0' is the index of the source. To find the index of the source you are using run the command:
$ pacmd list-sources

Thanks!
It is working now.
Good luck with fixing this. I would help you if I know how, but since I don't..
Impulse and Lyrics are my favorite screenlets, it is very odd why Impulse isn't part of Screenlets by default..

 Not working

Using 10.10 32 bit, with all dependencies installed. Bars aren't doing anything, using the decibel audio player app.

Nevermind, the problem is it crashes pulseaudio alot. I need to restart the screenlet if it crashes, which seems to be after every song that I play.

 Pulse

Pulse Audio can be very fickle. Here are some problems I've encountered while experimenting with the output stream.
On my laptop the internal audio input device sometimes gets muted so any thing that tries to read the stream will get no audio. On my desktop the internal audio input stopped worked all together despite all the pulse devices being present and unmuted. The former is easy to solve by unmuting the internal audio input device in pavucontrol. The latter I have yet to figure out.

 Adding to Screenlets PPA

Maybe you would be interested in developing your code under the project https://launchpad.net/indiv-screenlets. Notice that Screenlets 0.1.3 has implemented the requirements check and with Debian package the dependencies would be installed automatically. This would make installing of the Screenlet as well as getting the updates a bit easier for the users. And if in the project, all the packaging would be done automatically by a script.

There is some documentation on this as well as connected topics at http://www.screenlets.org/index.php/Documentation#Why_should_I_add_my_Screenlet_to_individual_Screenlets_project.

 Changing sensitivity?

Great screenlet and livens up the desktop :)
Is it possible to set the sensitivity of the applet? When I use my desktop speakers everything's fine as I can turn down the speaker volume although the system spews out att full volume, but when I use my headphones via a USB-soundcard I have to set the out volume so low that the visualizer doesn't react at all.
