Welcome to Sonic Visualiser!

Chris@119: Chris@119:

Sonic Visualiser is pretty complex, but you can use it for simple Chris@119: things very easily. Try importing an audio file and using the Pane Chris@119: menu to add some different views of it.

Sonic Visualiser's window is organised into panes and Chris@119: layers. To begin with, you have one pane. Import an audio Chris@119: file to see it displayed in a waveform layer on that pane.

Chris@119: Chris@119: Chris@119: Chris@119: Chris@119: Chris@119: Chris@119:

Each pane can contain any number of layers, which appear stacked Chris@119: from "front" to "back" on the same timeline. A layer can contain a Chris@119: view of audio, or of points (time instants) or data plots (time-values).

Chris@119: Chris@119: Chris@119: Chris@119: Chris@119: Chris@119: Chris@119:

There's a layer property box shown to the right of each Chris@119: layer, with one tab for each of the layers on that pane. Click on a Chris@119: layer's tab to bring that layer to the front. You can then adjust its Chris@119: colour and other display properties in the property box.

Chris@119: Chris@119:

The first tab is always for the pane itself, which has a few Chris@119: adjustable properties of its own.

If you have more than one pane, only one of them will be "current", Chris@119: marked with a black bar at the left side. Just click on another pane Chris@119: to make it current. Most editing operations affect the layer that's Chris@119: at the front of the current pane.

You can use different zoom levels for different panes by un-checking Chris@119: the Global Zoom control for one of them. By default, all panes will Chris@119: zoom and scroll together.

You can speed up and slow down playback using the Playback Speedup Chris@119: control in the bottom-right of the window.

The Transforms menu lists things you can do to extract features from Chris@119: or process your audio. The available outputs of any Vamp Chris@119: feature-extraction plugins or LADSPA audio effects plugins you have Chris@119: will show up here.
