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.

Well there are two ways currently, if you enable "Move Window" compiz plugin then you can use alt + left click to move it where ever you want.

You can also edit line:
273: win.move( screen_rect.width / 2 - width / 2 + screen_rect.x, screen_rect.height / 2 - height / 2 + screen_rect.y )

and change it to:
273: win.move( screen_rect.width / 2 - width / 2 + screen_rect.x, screen_rect.height - height + screen_rect.y )

 Compability with pulseaudio

Your little widget looks very cool but I have a great problem.
In order to make your widget work, I must install esound. My system runs on pulseaudio system, so in order to make it work, I have to uninstall pulseaudio and install esound, but if I do this, I will lose my system's sound!

Is there is any way to make your widget work with pulseaudio? It would be awesome.

P.S: Esound is now considered deprecated in some systems like mandriva, maybe in the future it will be for other distributions.

yea, realize esound is becoming depreciated and I will need to find a better alternative when i get the time to figure it out but i am on Ubuntu 8.10 and pulseaudio is the standard sound server for it. you can load a ESOUND compatibility module which is what i am doing that implements a compatible protocol for most all ESOUND compatible programs so esdmon is really monitoring the pulseaudio socket.

In Ubuntu and Debian the package is called pulseaudio-esound-compat

I've downloaded and installed that package for mandriva (it exists in the repos), but for some reason when I have banshee turned on and listening music, spectrolet will not take a single action! It is only a blue and red bar in the middle of the screen doing nothing...
Maybe spectrolet is not ready to capture sound from speakers with the esound compability package?

it is ready because I use the esound compatibility package with pulseaudio. You have to install the complatibility package as well as esound-clients (not esound-common, sorry my documentation was wrong). I am using esdmon which you probably don't have installed so now that you have esound compatibility installed you can install esound-clients and it should work with pulseaudio. I am hoping within a month I can find a way to use pulseaudio directly.

NOW Compatible with PulseAudio. After an hour of messing around Spectrolet now uses PusleAudio directly and not ESOUND. So there ya go!

Many thanks ianimal! Works wonderfully now!
As I can see, the entire widget as been created in python, so, making it as a screenlet would be the final touch, since many of the people who like this maybe want it: or in a single desktop or maybe hidden and after invoking the widget layer make it visible again or maybe both.
But for nows works greatly! Oh btw, there is a way to change the color of the bars in the code? If yes where to look for it?

dspencer82,

ianimal explains how to change the colours on the first comments page.

I have changed mine to white bars with orange peaks. I also changed the size of the spectrum bars from 16 to 8. You can see my screenshot here if this helps:

hey dspencer82, I've been working on improving impulse. You can now switch themes but you cannot change the colors unless you edit the code. Menu's to change them will be in the next release. Just like any other screenlet if you click on it a gear and X button appear in the top right corner of the screenlet. If you click the X, the screenlet closes, if you click the gear, the options menu will appear, and that is where you can switch between the themes. Now it can be difficult to click on Impulse because you must click on a pixel that is not the desktop background for the icons to appear. This is a bug in screenlets. The icons should really appear when you hover over any screenlet, not by clicking a filled pixel.
