Sonic Visualiser Description

Sonic Visualiser is an open-source audio analysis and annotation utility that displays the waveform of a music file, enabling you to get an insight of what is behind the output sound.

Variate format support and importing capabilities

Mainly addressed to music technicians, it can display a graphical representation of the audio signal for each channel and annotate loaded data for easier identification of segments.

It aims to provide a user-friendly tool for displaying spectograms and audio waveforms, ensuring compatibility with some of the most common audio formats (such as WAV, MP3, AIFF, AVR, FLAC, OGG, RAW), as well as less popular file types (AU, CAF, HTK, IFF, MAR, MPC, PVR, RF64, SDS, W64, WVE, XI). Moreover, it enables you to import musical note data from locally stored MIDI files and display it alongside the waveform.

Visualization, comparison and annotation

The application features options for modifying the way data is displayed. As such, you can freely adjust the zoom level both horizontally and vertically, so as to focus on any area of the waveform and analyze it in detail.

The selection tools enable you to define waveform sections and compare them much easier. For your convenience, Sonic Visualiser can also slow down the playback to such an extent that it reaches 10% of the initial speed.

One of the worth-mentioning features is the possibility to import and overlay annotation layers (CSV, LAB, MID, TXT) on top of waveform representations. Furthermore, it comes with a set of integrated plugins that allow automatic calculations of annotations, taking into account tuning and sound pitch.

Explore the content of audio files

Sonic Visualiser enables you to explore and get close-ups on the structure of an audio file, providing advanced annotation options to help you write down your findings. It comes with a broad tool set and options for managing spectrum data and layers, allowing audio playback and signal comparison.
