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.

Hey,
Thats not the problem with any particular screenlet but screenlet itself. I've used ring meters and had the same issues. Try this instead of restarting logout, login and then restart or else wait till next update of kernel (generally it get fixed with kernel update). The third solution I don't remember but I think it had something to do with modifying config for screenlets. But for me login logout worked so never tried it. Hope it will work for u as well :)

90%! really? Thats extremely high, very strange. It runs at an average of 3% CPU on my system. I can't imagine your computer is that dated. I see you are a programmer, if you feel inclined I'd be interested to see a profile of impulse on your system. You can get the code here: https://launchpad.net/impulse.bzr

Well it depends on which theme I use. The Circle LCD uses almost all of my CPU. The others run at about 30%. And it's not outdated, it's a Core 2 Duo T1700.

I might take a look at the code, but I can't promise anything since I'm rather busy lately.

Good job so far though.

I have same problem.
Core2Duo @1.8GHz, and Impulse uses around 30% of my CPU (even without any sound - Idle).
By the way, it is really cool thing :)

Hi I installed it successfully but when I launch impulse from inside Screenlets it only shows a flat red line and it does nothing!
How can I fix this?

Make sure you downloaded the right version to match your cpu. Make sure pulse audio is installed and running correctly. If those are both right everything should work fine. If they are right and its still not working, let me know and we can dive in further to try and figure it out.

Okay, so this is really bugging me: I installed the screenlet without a problem, but when i try to launch it, nothing happens... So I tried some different things, but nothing worked.
I launched it in a terminal just to see what was happening, but no errors occured, it just said that it was overiding options because it found a theme.

I've also tried uninstalling it and reinstalling it (several times), but to no avail.

By accident however (compiz crashed) I found out that as soon as compiz isn't running, "Impulse" works fine. By typing "emerald --replace" which makes all my window decorations look really bad, Impulse starts, so it seems to be some sort of conflict with compiz.

I'm running Ubuntu Jaunty BTW.

Same problem here. Also on Jaunty. Strange though, I have one computer where it works fine and this one, a newer computer, where it doesn't work at all. So it works well on an old computer but not on a new computer (bought this 3 days ago). Also tried installing and un-installing numerous times and it still doesn't work. All my other screenlets work fine.

This is very strange, what videocard/driver do you both use? What other screenlets (if any) do you use and do they work fine?

Okay... I got it working now - don't know how, but suddenly, it started working without a hitch and have been working flawlessly ever since, so I don't know if it is worth pursuing the matter any further... Anyway, if you suspect there might be some sort of glitch, I can inform you that I am running Jaunty on a T7300 2.0 GHz Core2Duo with a 256M Geforce 8800M GS running proprietary drivers.

I would also like to be able to use this screenlet on my desktop but am unable to do so for the same reason. I am also running Jaunty.

but it seems to only sample the music every 5 seconds or so, so it gets stuck in the same shape until the next update, not moving at all. What's going on?

thanx for this great screenlet. It's the best screenlet ever.
I'm using Jaunty and have two sound cards... one intergrated HDA Intel and the other one is SB Live PCI. When I listen music over HDA Intel there are no visualisations in this screenlet. I have to move the stream to the other soundcard to be able to see the visualisations. Is there any way to fix this issue?thx

Click on Impulse in the screenlets manager and click "Close All" on the left side bar. Hit "Alt+F2" and type in "gnome-terminal", then click run. When the terminal pops up type in this command:

.screenlets/Impulse/ImpulseScreenlet.py

If the output is long just P.M. it to me otherwise just reply to this comment with the output.
