4. Technical Description
    Summary

	This project integrates snack into Solaris.
	This project requests a minor binding.

4.1 Proposal

The Snack Sound Toolkit is a open source package. It is designed to be used
with a scripting language such as Tcl/Tk or Python.  Using Snack you can create
powerful multi-platform audio applications with just a few lines of code.

With features such as:

    * High level sound objects, with flexible storage management and streaming
      support.
    * Multiple simultaneous playback and recording threads (system dependent).
    * All audio data handled as floating point internally for fast and accurate
      computations.
    * Multi-platform support.
    * Script compilation tool included, for easy deployment using stand-alone 
      executables.
    * Filters which can be used to process sound objects or during playback for
      on-the-fly operation.
    * Visualization with waveforms, spectrograms, and spectrum sections.
      Postscript support.
    * Real-time visualization/spectrum analysis.
    * Web enabled, possible to run scripts embedded in web pages through the use
      of the Tcl Plugins 
    * Extensible, new commands, filters, and sound file formats can be added
      using the Snack C-library.
    * Lots of examples included as well as a skeleton C-extension.
    * Supported sound file formats: WAV, AU, AIFF, MP3, CSL, SD, SMP.

The first consumer of the library is aMSN -- a free open source MSN Messenger
clone which is an Indiana package. AMSN uses snack for voice clips support.

32 and 64 bit libraries will be provided.

snack provides a file in html format and examples describing snack tcl commands
that will be released with the integration. A new man page will be provided
pointing to the html documentations. They are included in case directory.
