-This is a visualization based on on synaesthesia. (see the synaesthesia
-README below)
-
-This implementation is taken from alsaplayer: http://www.alsaplayer.org/ It
-is based on synaesthesia version 1.3 (or maybe 1.4, I'm not entirely
-certain), with some modifications by Richard Boulton to try and ensure that
-something interesting is displayed for both very quiet and very loud music.
-
-Note: only one instance of this plugin may be created at a time: it has a
-lot of static data. This should be fixed (and it shouldn't be hard to do
-so, either).
-
-----------------------------------------------------------------------------
-
-SYNAESTHESIA v2.0
-
-Introduction
-============
-
-This is a program for representing sounds visually from a CD or line
-input or piped from another program. It goes beyond the usual oscilliscope
-style program by combining an FFT and stereo positioning information to
-give a two dimensional display. Some of the shapes I have observed are:
- * Drums: clouds of color, fairly high
- * Clean guitar: several horizontal lines, low down
- * Rough guitar: a cloud, low down
- * Trumpet: Lots of horizontal lines everywhere
- * Flute: A single horizontal line, low down
- * Voice: A vertical line with some internal structure
- * Synthesizer: All kinds of weird shapes!
-
-Synaesthesia can run in a window in X or full screen using SVGAlib.
-
-The display represents frequency as vertical position on screen,
-left-right position as left-right position on screen. It can also
-understand surround sound encoded music, and shows ambient noise
-in orange.
-
-X-Windows support was added in version 1.3, as well as a major redesign
-of the interface. You can use Synaesthesia as a fully functional
-CD player, suitable for use while working.
-
-There is command line support for play lists and piping from another
-program (such as an mp3 player).
-
-Usage
-=====
-
-Synaesthesia should work on Linux and BSD systems. (Note: I don't
-have access to a BSD system myself, I have to rely on patches -- if it
-doesn't work, please tell me!) LinuxPPC users may have to use the pipe
-mode rather than taking sound input from the CD player, as I believe
-sound recording is not yet implemented.
-
-Compile Synaesthesia by typing
-
- make
-
-then install it by typing
-
- make install
-
-This will create three versions of Synaesthesia:
-
- synaesthesia - full screen SVGAlib version (Linux only)
- xsynaesthesia - Version that runs as a window in X
- sdlsynaesthesia - Version that uses the SDL graphics library
-
-If you want to use the SDL version, you need to get SDL from
-http://www.devolution.com/~slouken/SDL.
-
-You will need to run Synaesthesia as root to run it full screen
-with SVGAlib. Other varieties can be run by any user providing you
-provide permissions on /dev/dsp, /dev/cdrom, and /dev/mixer.
-
-Synaesthesia creates a configuration file, named ~/.synaesthesia,
-to store settings such as brightness, color, and window size, as
-well as which devices to use to control sound input.
-
-BSD users will have to edit this file to set the CD-ROM device name
-before using Synaesthesia in order to control the CD.
-
-Run Synaesthesia with no parameters for further information on how to
-use it.
-
-Notes for code rippers
-======================
-
-This program contains code that you may wish to use in your own projects.
-If you want to, please do. (For example, you might want to add some
-snazzy visual effects to your favourite MP3 or CD player)
-
-The actual code to do the mapping from sound to visual display is
-all in core.cpp, it should be fairly easy to disentangle from other
-parts of the program. It does make reference to some globals defined
-in syna.h, namely the #defines m (log2 of the sample size for each
-frame) and brightness, data (which stores the sound input), outputBmp,
-lastOutputBmp and lastLastOutputBmp (which hold the output), outWidth
-and outHeight (size of the bitmaps), and fadeMode, brightnessTwiddler,
-starSize and pointsAreDiamonds (various parameters affecting the display).
-
-The normal way to use it would be:
-
- Call coreInit() to set up some look-up tables
- Call setStarSize(starSize) to set up some more look-up tables
- Loop
- Put data into the data array
- Call fade() to apply the fade/wave/heat effect to the output
- Call coreGo() to add the next fragment of sound input to the output
- Display contents of outputBmp to screen
-
-There is a simple anti-aliased polygon drawing engine in the file
-polygon.h. sound.cpp contains code for driving the CD. xlib.c and
-xlibwrap.cpp contain code for setting up a window under X (originally
-ripped from the Xaos fractal viewer program :-) ).
-
-Authors
-=======
-
-This program is free. If you like it, or have any suggestions, please
-send me (Paul Harrison) an email (pfh@yoyo.cc.monash.edu.au).
-
-Thanks to Asger Alstrup Nielsen for many great suggestions, and for
-writing optimized 32 bit loops for fading and drawing to screen.
-
-Thanks to Roger Knobbe for porting Synaesthesia to FreeBSD.
-
-Thanks to Ben Gertzfield and Martin Mitchell for some small fixes to the
-CD controlling code.
-
-Thanks to Simon Budig for an improvement to the X code.
-
-Changes
-=======
-
-1.1 - Added surround sound decoding.
-1.2 - Fixed a bug in the ioctl calls to /dev/dsp.
-1.3 - Asger Alstrup Nielsen's optimizations added.
- Added X-Windows support.
- More options, redesigned interface.
-1.4 - Bug fixes, including a great reduction in
- "Sound: Recording overrun" warnings.
- New command line options: play lists and piping.
- Support for SDL.
-2.0 - Bug fixes: Fixed problem in xlib.c that caused occasional segfaults,
- several endianness problems fixed.
- New effects: Wave, heat, diamond shaped points.
- Piping sound now longer requires the twiddle factor.
- Yet another interface redesign.
- Partial support for LinuxPPC (pipe mode only)
