## What it is
Friture is a free, open-source desktop application for real-time audio visualization and analysis. It provides widgets such as a spectrum analyzer, rolling 2D spectrogram, octave analyzer, scope, pitch tracker, and delay estimator, plus a built-in audio signal generator.

## Use cases
- visualize live audio spectrum in real time
- analyze room acoustics for equalization
- identify feedback frequencies and harmonics
- measure reverberation and delay in a hall
- teach audio signal processing concepts
- generate test signals like sine sweeps and pink noise

## When to choose
- you need a ready-to-use GUI audio analyzer on Windows, macOS, or Linux
- you want real-time spectrogram or fraction-of-octave analysis without writing code
- you are tuning a sound system or equalizing a room

## When to avoid
- you need offline batch analysis of audio files rather than live input
- you need a scriptable library or CLI to embed in your own pipeline
- you require professional certified acoustic measurement standards

## Facets
- artifact type: application
- maturity: active
- function: audio-processing, data-visualization, gui
- domain: data-visualization, developer-tools
- platform: windows, python, cross-platform
- tags: spectrum-analyzer, spectrogram, real-time-audio, audio-analysis, room-equalization, pyqt, audio, macos, linux
