I'm looking for a real-time audio spectrum analyzer. It looks like GNU Radio has this feature but I receive the following after attempting to install using the build-gnuradio script for Ubuntu:

Installing prequisites...Your Ubuntu release must be at least 9.04 to proceed

Any assistance (including suggestions for other software) will be appreciated.

Thanks.

Thanks.

I need to analyze external sources (e.g., via microphone) for spectrum characteristics. I don't see that in Audacious. Unless I'm missing something...

In that case audacious is not what you're looking for. What version of Trisquel are you on?

That build script doesn't even know Trisquel exists and is baffled by the version number because it is so small. But we can probably temporarily change the version number to match the Ubuntu version your Trisquel version is based on for the time of running that script.

Does audacity have spectrum analyser capabilities? I've only used it
for recording and simple editing. Audacity should be in the
repositories. its home page: http://audacity.sourceforge.net

Apparently it has some capabilities although not realtime. It is in the repos.

I'm using Trisquel 6.0.

I assumed (apparently incorrectly) that the build script might know that it's based on a recent version of Ubuntu.

Thanks!

So, edit the file that script looks for the info. Just remember to fix it back afterwards!

sudo nano /etc/lsb-release

There you need to change the line DISTRIB_RELEASE=6.0 to DISTRIB_RELEASE=12.04

Then try the script. It's huge but I believe it should work without any more tampering. :)

Aaand then set back the correct version.

I subsequently found JAAA in the Trisquel software list and it's perfect for my needs (Grade 4 lesson about sound frequency).

Thanks!
