Real Time Audio Analysis In Linux - Stack Overflow
https://stackoverflow.com/questions/703128/real-time-audio-analysis-in-linux
I'm attempting to make a small program that will aid in tuning instruments. (Piano, Guitar, etc.). I've read about ALSA & Marsyas audio libraries. I'm thinking the idea is to sample data from microphone, do analysis on chunks of 5-10ms (from what I've read). Then perform a FFT to figure out which frequency contains the largest peak.

Friture - real-time audio analyzer - LinuxLinks
https://www.linuxlinks.com/friture-real-time-audio-analyzer/
Friture is a real-time audio analyzer. The purpose of Friture is to help analyze an audio signal to understand the characteristics of this signal (fundamental, harmonics, feedback, etc.), to describe the source/room/receiver behaviour (reverberation, gain peaks, etc.), or to make adjustments in the preprocessing (room equalization).
Is there a free realtime spectrograph available for Ubuntu?

This may be a bit overkill, but Baudline is an incredible real-time FFT spectrogram. It's not in Ubuntu repos, so you will need to download it on your own.It displays a real-time analysis of source signal, but it also allows to analyze pre-recorded data.
