I am pleased to release StrechPlayer 0.500, a time-stretching,
pitch-shifting audio file player. It is powered by librubberband, and
also features an A/B repeat. This is the first release of
StretchPlayer.

Note: I'm announcing this on composite-dev because this
program is effectively a prototype or experiment for
Composite. The intention for Composite is that every audio
clip will be able to be time-stretched like this.

USING THE PROGRAM
-----------------

You will need at least a 1200 MHz processor to use this program. It
also requires the following libraries:

* Qt >= 4.4 http://qt.nokia.com
* librubberband http://www.breakfastquay.com/rubberband/
* libsndfile http://www.mega-nerd.com/libsndfile/
* JACK http://jackaudio.org/
* CMake http://www.cmake.org/

After building, run the program like this:

$ stretchplayer

The GUI is pretty self-explanatory, and if you hover over the controls
a tool-tip should appear. The GUI also has several keyboard
accelerators.

ACKNOWLEDGEMENTS
----------------

My sincere thanks to Chris Cannam for publishing the RubberBand
library. I've wanted this thing since I was in High School. :-)
