This document is a reference manual for version 3.4 of Spat~, which runs on Max/MSP version 4.6.

Spat~3.4 is the final version of the "classic" IRCAM Spat~ library pending a major redesign of the Spat (version 4.0) scheduled for 2007. Spat~3.4 operates a unification of previous Mac/Windows versions and ensures UniversalBinary MaxMSP compatibility (Mach-o PowerPC + Macintel). The porting of the Spat~ library to universal binary was ensured by Remy Muller.
