AbstractNot too long ago real time audio synthesis and signal processing used to be restricted to dedicated hardware. In the mid-nineties software synthesizers entered the field of desktop computing.

At the same time software for real-time computer music systems moved from dedicated DSP's to desktop computers with diverging operating systems. PD (Pure Data) is a computer music systems that showed a great deal of flexibility, originally designed to run on SGI Irix and Windows NT machines, it has been ported to Linux in 1997 and runs on all major Desktop operating systems nowadays.

This was only possible because of its openness and availability as free software.This paper describes a new port of PD, this time not for a new operating system but for a new type of computers the PocketPC. The paper describes the capabilities of these small handheld devices nowadays and then goes on to describe different aspects of the software system derived from PD and called PDa.
