Copyright (C) 2006-2011 Nasca Octavian Paul, Tg. Mures, Romania

Released under GNU General Public License v.2 license

This is an experimental program for extreme stretching the audio.
Requirements:
- audiofile library
- libvorbis
- fltk library
- portaudio library
- libmad (for mp3 input)
- mxml library (for saving/loading parameters)
- not required, but you can use the FFTW library


This algorithm/program is suitable only for extreme stretching the audio.

There is lot room for improvements on this algorithm like:
- on sharp attacks to make the window smaller and larger on steady sounds. This avoid adding constant sidebands on steady sounds and smoothing too much the sharp sounds.
- even for small window, the sidebands produced can be lowered (how?)

Tips:
You can change the default output device with "PA_RECOMMENDED_OUTPUT_DEVICE" environment variable (used by PortAudio).
eg: set PA_RECOMMENDED_OUTPUT_DEVICE=1 #where 1 represents the index of the device; you can try other values for other devices

History:
20060527(0.0.1)
- First release

20060530(0.0.2)
- Ogg Vorbis output support
- Added a wxWidgets graphical user interface

20060812(1.000)
- Removed the wxWidgets GUI and added a FLTK GUI (because FLTK GUI is smaller)
- Added real-time processing/player
- Added input support for Ogg Vorbis files
- Improved the stretch algorithm and now the amount of stretch is unlimited (and on big stretch amounts, you don't need additional memory)
- Added "Freeze" button to the player
- It is possible to render to file only a selected part of the sound
- Other improvements

20060905(1.024)
- Added MP3 support for input
- Added bypass mode (if you click play with the right mouse button)
- Improved the precision of the position slider (now it shows really what's currenly playing)
- Added the possibility to set the stretch amount by entering the numeric value
- Added pause mode and volume control
- Added post-processing of the spectrum(pitch/frequency shift, octave mixer, compress,filter,harmonics)
- Command line parameter for input filename
- The file can be dragged from the explorer to the file text to open it

20090424(2.0)
- Added free envelopes, which allows the user to freely edit some parameters
- Added stretch multiplier (with free envelope) which make the stretching variable
- Added arbitrary frequency filter
- Added a frequency spreader effect, which increase the bandwith of each harmonic
- Added a frequency shifter which produces binaural beats (the beats frequencies are variable)
- Added 32 bit WAV rendering
- Other improvements and bugfixes

20110210(2.1)
- Added loading/saving parameters
- Added Linux Jack support (thanks to Robin Gareus for the patch)
- Added "Symmetric" mode of Binaural Beats
- Support for longer stretches - for the really patient ones - up to one quintillion times ( 10^18 x ) ;-)
- Fixed a bug which produced infinite loop at the end of some mp3 files (at playing or render)
- Fixed a bug in the mp3 reader
- other minor additions

20110211(2.1-0)
- Increased the precision of a paremeter for extreme long stretches

2011????(2.)
- Added an option to preserve the tonal part or noise part
- Ignored the commandline parameters starting with "-" (usefull for macosx)

Enjoy! :)
