[Trisquel-users] Real-time audio spectrum analyzer

[nycbone]

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.
