Sonic Visualiser eats that.)Ĭheck out our roundup of affordable Studio Monitors. The work Sonic Visualiser does is intrinsically processor-hungry and (often) memory-hungry, but the aim is to allow you to work with long audio files on machines with modest CPU and memory where reasonable. Sonic Visualiser is pervasively multithreaded, loves multiprocessor and multicore systems, and can make good use of fast processors with plenty of memory. Even if you have to wait for your results to be calculated, you should be able to do something else with the audio data while you wait.
To provide the best available core waveform and spectrogram audio visualisations for use with substantial files of music audio data.The design goals for Sonic Visualiser are: Export audio regions and annotation layers to external files.Time-stretch playback, slowing right down or speeding up to a tiny fraction or huge multiple of the original speed while retaining a synchronised display.Select areas of interest, optionally snapping to nearby feature locations, and audition individual and comparative selections in seamless loops.

Play back the audio plus synthesised annotations, taking care to synchronise playback with display.Import note data from MIDI files, view it alongside other frequency scales, and play it with the original audio.Import annotation layers from various text file formats.Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on.View the same data at multiple time resolutions simultaneously (for close-up and overview).Overlay annotations on top of one another with aligned scales, and overlay annotations on top of waveform or spectrogram views.Annotate audio data by adding labelled time points and defining segments, point values and curves.Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters.
Sonic Visualiser contains features for the following:

The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.Īs well as a number of features designed to make exploring audio data as revealing as possible, Sonic Visualiser also has powerful annotation capabilities to help describe what you find, and the ability to run automated annotation and analysis plugins.įeatures include sophisticated spectrogram views multi-resolution waveform and data displays manual annotation of time points and curves measurement capabilities from spectrogram and spectrum playback at any speed looping and playback of discontiguous selections ability to apply standard audio effects and compare the results with their inputs and support for onset detection, beat tracking, structural segmentation, key estimation and many other automated feature extraction algorithms via Vamp audio analysis plugins. Sonic Visualiser is an application for viewing and analysing the contents of music audio files.
