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.

Hmm, that is because i'm guessing you are using compiz and have the Fading windows plugin enabled which dims unresponsive windows. I didn't have this enabled originally but with it enabled i now see the gray problem you are experiencing. This should be a simple fix in my code. I am assuming it is because I don't start gtk.main and instead am using my own loop. But anyway I will fix this and post the update today or tomorrow.

Try the new revision, Spectrolet 0.1a1r6. It should fix the problem you were having

Well currently its just hardcoded, eventually i will have a theme, animation editor but if you want to change it, you can go into the code and change it on line 77:


77: cr.set_source_rgba( 0.0, 0.6, 1.0, 0.8 )


obviously the first number is red, second is green, third is blue, and fourth is alpha. if you only know the html (hex) color representation like #CC9966 you can convert that by entering it like:


77: cr.set_source_rgba( 0xCC / 255.0, 0x99 / 255.0, 0x66 / 255.0, 0.8 )

thank you,

When the new features have been implemented would you be so kind as to send a pm as i would like to test this further.

I have around fifty work pc's and would like to install this on all for the eye candy appeal and it is a great talking point.

I would also like your permission to do so.

Regards John

Will do, i am working on adding fourier transform option to visualize the frequency by power instead of visualizing the straight sound wave. I'll let you know about updates.

You can do anything you want with this without my permission as long as it abides by the GPL license , which is pretty much anything you want!

and thanks for appreciating my work!
