Sonic Visualiser Overview
Sonic Visualiser is a free, open-source application for Windows, macOS, and Linux built for viewing and analyzing the contents of audio recordings, aimed at musicologists, researchers, and anyone studying music in detail. Rather than simple editing, it focuses on visualization and analysis: it can display waveforms, spectrograms, spectrum, and pitch, overlay annotations, and run analysis plugins (in the Vamp format) to detect features like beats, notes, keys, and tempo. It is widely used in academic music research and by musicians transcribing or closely studying recordings. Its analytical depth makes it a specialized but powerful free tool. Saved as a full installer, Sonic Visualiser can be set up on a system with no network access. This page links to Chris Cannam's official Sonic Visualiser download.
