From https://www.sonicvisualiser.org/:

  Sonic Visualiser is a free, open-source application for Windows, Linux, and Mac, designed to be the first program you reach for when want to study a music recording closely. It's designed for musicologists, archivists, signal-processing researchers, and anyone else looking for a friendly way to look at what lies inside the audio file.

## Installation

Install the sonic-visualiser package.

## Known issues

### Play button does not play the track (No audio)

Sonic visualiser (or at least Arch's build) requires PulseAudio to be set up to hear anything. For ALSA-only users, using apulseAUR as described in PulseAudio compatibility is confirmed to work.

    $ apulse sonic-visualiser

The terminal messages will still have `WARNING: AudioFactory::createCallbackIO: Failed to open JACK I/O` but can be ignored, audio will play with no issues.
