Sweep 0.5.12 Development Release

Sweep is an audio editor and live playback tool for GNU/Linux, BSD and
compatible systems. It supports many music and voice formats including
WAV, AIFF, Ogg Vorbis, Speex and MP3, with multichannel editing and
LADSPA effects plugins. 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:


NEW in this release:

        * an updated Italian translation from Yuri Bongiorno

        * resample (sample rate conversion): change the sample rate of a
        file, for example from CD format to DAT format, or to any arbitrary
        sample rate. This requires Erik de Castro Lopo's newly released
        libsamplerate, available from http://www.mega-nerd.com/SRC/

        * preview cut: hear how the area around the selection will sound
        after the selection is cut out, including the parts between
        selection regions for multi-region selections.

        * preroll to cursor: play one second of sound leading up to the
        cursor; useful for hearing the cursor position without moving it.

Bugs were fixed in MP3 loading and pitched playback (using QWERTY keys).



Some interesting audio recordings of Scrubby are at:
