MIDI is the most obvious. > For midi: wouldn't it be possible to allocate block of the upper bound-size. I mean midi is constrained by the transfer-rate. Commands can be placed into the buffer at the point in time when they should occure. Ofcourse they need to check if the time-slot is still free and should use the next free one.

[linux-audio-dev] Sweep 0.5.4 -- !ybburcS olleH

by Conrad Parker

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: http://prdownloads.sourceforge.net/sweep/sweep-0.5.4.tar.gz?download 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: http://www.metadecks.org/software/sweep/scrub.html Summary of library dependencies: * GTK+ 1.2 (standard in most distributions) * libsndfile-1.0.0, available at: http://www.zip.com.au/~erikd/libsndfile/libsndfile-1.0.0.tar.gz * libtdb, available in many distributions or at: http://www.sourceforge.net/projects/tdb Screenshot: http://www.metadecks.org/software/sweep/images/screenshots/sweep_20020813.p… 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. More information is available at: http://www.metadecks.org/software/sweep/ Thanks to Pixar Animation Studios and CSIRO Australia for supporting the development of this project. enjoy :) Conrad.
