Sweep 0.5.4 Development Release

Sweep is a sound wave editor, and it is now also generally useful as a
flexible recording and playback tool. Inside lives a pesky little virtual
stylus called Scrubby who enjoys mixing around in your files.

This development release is available as a source tarball at:


Changes since version 0.5.3 (September 5 2002) include bug fixes for
playback during destructive operations and for edits of tiny regions,
and improvements in configuration checks for libsndfile-1.0.0.

Additionally, scrubbing is now working for reverse playback, and has been
tuned for responsiveness independent of sample rate.

There is now a web page introducing Scrubby and outlining a few simple
editing and live performance techniques:


Summary of library dependencies:

	* GTK+ 1.2 (standard in most distributions)

	* libsndfile-1.0.0, available at:


    	* libtdb, available in many distributions or at:



Sweep is designed to be intuitive and to give you full control. It includes
almost everything you would expect in a sound editor, and then some:

	* precise, vinyl like scrubbing
	* looped, reverse, and pitch-controlled playback
	* playback mixing of unlimited independent tracks
	* looped and reverse recording
	* internationalisation
	* multichannel and 32 bit floating point file support
	* LADSPA 1.1 effects support
	* multiple views, discontinuous selections
	* easy keybindings, mouse wheel zooming
	* unlimited undo/redo with fully revertible edit history
	* multithreaded background processing
	* shaded peak/mean waveform rendering, multiple colour schemes

Help wanted! Sweep needs testing; please report any problems encountered!
Urgent development is required in the following areas: ALSA and Jack support,
updating of translations and user documentation. (NB. Sweep works fine with
ALSA under OSS emulation -- the native ALSA support needs some fixing).

Sweep is Free Software, available under the GNU General Public License.

Thanks to Pixar Animation Studios and CSIRO Australia for supporting the
development of this project.
