Sonic Visualiser 2.3 / 2.4 Beta 1
Instantly generate waveforms for your audio files and visualize the spectrograms
With Sonic Visualiser’s help you will be able to study musical recordings and perform an in-depth analysis of the audio using the provided tools. Consequently, you can load audio files in WAV, OGG and MP3 formats and generate their waveforms.
Most of the tools and features provided by Sonic Visualiser can be easily accessed from the top toolbar while the right side panel helps you switch between different layers with just a couple of mouse clicks.
Adjust parameters and work with the dynamic spectrograms
The generated spectrogram views are interactive and allow you to adjust and display various parameters with ease. Thanks to the context menu you can quickly add new layers with spectrograms, edit, rename and delete layers with ease.
As follows, you can overlay layers with time instants, time values, notes, regions, text, images, waveforms, simple spectrums, spectrograms, peak frequency and melodic range spectrograms. On top of that, you can take control over the playback and slow down or speed up the playback speed.
Display multiple spectrogram views in different panes or in the same pane
Moreover, Sonic Visualiser enables you to add multiple panes, each pane with its own set of layers that you can add, remove and edit. As a result, you can work with multiple spectrograms at the same time and perform a detailed and accurate analysis of your file.
In addition, Sonic Visualiser offers a powerful annotation tools that helps you write notes, describe your discoveries, add labelled time points, define segments, curves and point values.You also have the option to overlay annotations on top of each other or on top of waveform and spectrogram views.
To conclude, is a powerful, yet easy-to-use application that makes audio visualization and analysis a breeze for both experienced and novice users.

- Add support for left/right scrolling using a two-finger touchpad gesture (where available)
- Make the octave numbering into a configurable option, and change the default. Previously Sonic Visualiser labelled middle-C as "C3"; now it labels middle-C as "C4", a more common standard in the world outside MIDI sequencer software. The previous system is available as an option in the Preferences. This affects only the visible labels: there is no change to analysis or to the file format
- Sonify time-value layers. Any time-value curve whose scale unit is set to Hz will now acquire a playback toggle control; this control is off by default, but if it is switched on, the curve will be played back using a variable-frequency sound generator
- Add support for playback of note layers with non-MIDI frequencies (formerly the note playback was limited to exact MIDI pitch)
