Screenshots.

Sweep is a very interactive sound editor which makes heavy use of audio feedback to make your tasks of manually analysing and editing sounds easier. Of course these screenshots cannot capture the interactivity -- you will have to try Sweep out for yourself to experience that. These screenshots show the most common editing windows and dialogs that you will encounter.

	General usage. This section introduces Sweep's main waveform view, extended selections and edit history.
	File dialogs. Sweep supports many file types, including PCM (WAV, AIFF etc.), voice formats including Speex, and the Ogg Vorbis perceptual audio codec. This section displays the options available for loading and saving various different file types, and for creating new files.

Getting around in Sweep.

Main window

This is the main application window in Sweep. The two waveforms shown represent the left (above) and right (below) channels of a stereo WAV file. The grey regions indicate peaks and the dark regions indicate average values for the audio data. Time offsets in hours, minutes and seconds are shown above the waveforms. This window also includes a standard editing toolbar and playback controls.

 Zoomed in

You can zoom right in to individual PCM data values using the mouse wheel if available, arrow keys or the zoom control located in the top right corner of the window. The number in the dropdown box indicates the duration of sound visible in the window -- in this case 0.003 seconds.

Vertical Zoom

For greater precision, you can zoom the waveform display vertically, either by rolling the mouse wheel over the dB markings on the left side of the window or by pressing Shift and Arrow Up/Down. You can scroll the waveform display up and down by dragging the dB ruler on the left side of the window.
