Sweep 0.5.5 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 0.5.4 include major bugfixes for LADSPA plugin
handling and improvements in scrubbing usability.
Summary of library dependencies:
* GTK+ 1.2 (standard in most distributions)
* libsndfile-1.0.x, available at:
* libtdb, available in many distributions or at:

* play.c: made scrubbing independent of nr. channels (scrub_rate)
* ladspameta.c: fixed segv in handling of mono files and filters
* callbacks.c: made scrubby stop if space is pressed (so you don't
lose your position by playback continuing when scrubby is released,
suggestion from swh)

* ladspameta.c: fixed channel de-interleaving/interleaving
* ladspameta.c: switched to SweepFilter, instantiated separate
LADSPA_Handle for each iteration & internalised processing loop
* ladspameta.c: fixed detection of upper and lower bounds
* param.c: changed step relative to upper and lower bounds
* ladspameta.c, reverse.c, normalise.c: fixed divide by 0 bug in
calculating percent for regions shorter than 100(ish) samples
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
* 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.
