Introduction +--------------- + +SMLib is an external objects library for PD (pure data). It complements PD +with a set of objects for vector processing, vector analysis, vector +synthesis, number stream analysis, number stream filters. + +I was missing objects that could do dsp-like operations on control signals. +PD is event-driven by nature (except the dsp-objects and [delay], [metro], +...). A slider that does not change does not transmit anything. Event-driven +events can be sampled by eg. using a [float] with a [metro] on its main input, +and a slider on its right inlet. SMLib has objects designed to process such +streams. Eg. [lavg] is a leaky integrator, it smoothes abrupt changes. Leaky +processes are interesting in mapping because our attention is also leaky. +Eg. [hp] is a high-pass filter (just like [hp~]), and it only passes changes, +and decays to zero when there are no changes. Likewise our attention shifts +towards remarkable changes in our environment. You can detect 'events' in +float streams with [threshold]. A vector is a list of floats. + +These objects are suitable for gesture and high-level music analysis +prototyping. + +This library is written by Johannes Taelman (johannes.taelman@rug.ac.be). The +code is free+open (GNU GPL license). I have only tested/compiled the code on +win32, but porting to linux or macOs should be easy. + +2.

Installation +--------------- + +Requires PD on the win32 platform (for now). Put SMLib.dll in a directory in +your PD path. Put the help patches in pd\doc\5.reference. + +Start PD with "-lib SMLib" + +4. Getting started +------------------ + +Start PD. + +Create a new patch. + +Create an object [SMLib] + +Right-click on this object after creation. Choose help. + +This gives you the main SMLib patch with all objects and a brief explanation +of them. Choose help for the objects to get details.
