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'm using mint 10, and it installed fine but it doesn't play anything. How do you connect audio to it? Theres just a drop down with numbers, i'm confused.

 Audio Source Problem

 
 by JeanVW14 on: Feb 10 2011
 
Score 50%

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

 Volume Problem

 
 by brainpower on: Feb 12 2011
 
Score 50%

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!

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...

Open the properties of the screenlet, go to Options->Impulse and change the colors... (Bar color, Peak color, Background color)

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?

coz
