Friture - fft on linux A sound visualizer I am a linux user from 2008, and i would never exchange Linux for other OS. however, there are some minor pieces of software I miss from my old windows XP time. One of them is Winamp, namely the voice printer visualization. I know I could run Winamp with Wine, but... it is not as good! While doing some search on linux FFT software, I found Friture . It is wonderful, much better and with a lot of functionality! As any program, it can "listen" to some specific device, like a microphone, ou to the sound card monitor. It is really amazing! It comes as an appimage, so just download and run. See your sound!
