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.

I've just installed impulse for the "n" time and i realised that the speed of the bars is too slow, looks like it it freezing. I've tried to change the settings, even change the peack_acceleration in the .py configuration file, no result. I used impulse before without any issues.

just change the number of columns and rows in the screenlets settings however you like...
if the peaks don't go up very much, consider using my version with the "amplifier"

after impulse restart, I must tweak the audio index again to get it work.
And I couldn't right-click or drag on my impulse either.
How to fix it?

I'm using ubuntu 10.10.

Thanks.

hey guy,
I notice this is not sensitive unless the volume is near or at 100%!!
Is it possible to make it as highly sensitive throughout the volume range?

hi im running 10.04.1 64bit on a toshiba satellite l675. i WAS running 10.04.1-32 bit but switched to 64 recently. when i was on 32 bit i had this screenlet working just fine, a bit buggy but no deal-breakers. now that ive switched to 64 bit, i have redownloaded the 64 bit version of impulse, uninstalled the old, installed the new, and now impulse fails to launch at all. please help!

Open a terminal and cd to the directory where your ImpulseScreenlet.py is located... type there: "./ImpulseScreenlet.py" and then there you may see, why it won't start...

Hi,
first: great screenlet, it's awesome :D

but I had a problem: my audio source is too silent, so the bars were hardly moving...
I solved this problem by adding an amplifier to it, which amplifies the bars.

I want to share my solution, if someone out there has the same problem :D

P.S.: @ianimal: If you want to add it to your screenlet, feel free to do so :D

Sorry got it for my own..
For those who dont know:
Just exchange your code in ~/.screenlets/Impuse/ImpulseScreenlet.py with the code from the link
Then you can set the Amplifier in the Screenlet Options

nice work! thanks!

Thanks for the great screenlet.. one of my favorites.

I'm having an issue with the 64 bit version - the sensor does not pick up the audio (stays flat), and when I go to the audio source it is on '1'. If I change it to 2, then back to 1 it suddenly starts working. Just a bit annoying having to do this every session to get it working.

Is there any quick workaround?

Thanks,
Jean

I solved it.
open .screenlets/Impulse/ImpulseScreenlet.py

In the very beginning there is the line

audio_source_index = 0

Just chaning the 0 with the number of my source worked for me

You legend!

Thanks mate. This has been a big papercut for me for a while now.
