Visu is a real-time spectrogram plugin for audio analysis and visualisation.

A spectrogram displays how the frequency content of a signal changes over time, with amplitude represented by colour. Think of it as an audio X-ray, useful for spotting transients, analyzing pitch and harmonics, detecting unwanted noise, and tracking how a sound evolves.

Alongside a classic spectrogram mode, Visu includes an enhanced mode with greater precision in both time and frequency. It uses time-frequency reassignment (a technique that relocates energy to its most accurate position using phase information) resulting in sharper transients, clearer pitches, and a more detailed image.

Key Features:
Classic and Enhanced spectrogram modes
Freeze and PNG export
HiDPI support
