Friture is a real-time audio analyser that helps users investigate the frequency, amplitude and timing characteristics of sound. It provides several graphical instruments for examining live audio signals through a sound card or other supported input device.
The application is useful for audio engineering, acoustics education and diagnosing problems in sound systems. Its displays can help identify feedback frequencies, investigate room responses and compare signals captured from different sources.
Friture uses configurable widgets that can be arranged together in a single workspace. This allows several aspects of an audio signal to be examined simultaneously without switching between separate applications.
This is free and open source software.
Key Features
- FFT spectrum analyser displaying audio energy across the frequency range.
- Configurable FFT window length and display response time.
- Peak markers identifying prominent frequencies and recent maximum levels.
- Rolling two-dimensional spectrogram showing frequency changes over time.
- Fractional-octave analyser with selectable frequency-band resolution.
- Oscilloscope displaying the audio waveform against time.
- Peak and RMS level meters with decibel full-scale measurements.
- Delay estimator measuring the time difference between two input channels.
- Cross-correlation techniques for analysing signal alignment.
- Freeze the analysis display to inspect transient events and feedback frequencies.
- Signal-generation facilities for acoustic testing and measurement.
- Configurable audio input selection and stereo channel handling.
- Dockable widgets supporting several simultaneous analysis views.
- Cross-platform support – runs on Linux, macOS, and Windows.

I wanted to try Friture and I am running the latest release of Ubuntu. I went to the site, downloaded the install file, ran the two commands from the site and … nothing. I went to their forums and found the general forum and I was going to post there but I could find no way to leave a post. Very, very frustrating.
Run the commands from a terminal and paste the output here, and I’ll be happy to investigate.
