MSP performance tests

Posted by admin on December 12, 2007

This mini-experiment was conducted to determine the computational overhead of various MSP routines common to my workflow. As any good computer scientist should know, optimization is useless without benchmarking!

Jérôme Daniel, Decoding, and the Platonic Sampling Regularity

Posted by Franz Zotter on December 8, 2007

Jérôme Daniel is one of the hardest working researchers in Ambisonics soundfield synthesis. In his thesis Daniel01 and many of his papers, Daniel03,Moreau06,Bertet07,Daniel07, he describes in very detail nearly everything needed for higher-order Ambisonics (HOA); i.e. these are also important for central, directivity pattern radiating spherical loudspeaker arrays, as well as spherical microphone arrays.

Regularity of the Platonic Samplings:

Matrix Library for pd

Posted by Franz Zotter on November 6, 2007

The [iemmatrix] library for pd has been started by Hannes Zmoelnig, an important member of the pd-developers community, at the IEM in Graz, with GPL license. It is purely based on pd-messages with the matrix selector with subsequent dimensions and values, e.g. [matrix 2 3 1 2 3 4 5 6 (, by convention the matrices are read row-wise here, i.e. the second row is "4 5 6".

Fix your MOTU 828

Posted by Michael Zbyszynski on November 5, 2007

A couple of times I've had problems with MOTU 828mkII's and fixed them by doing these things:

Perform a system reset:

- Unplug the firewire
- press the button "setup", turn full right until "factory default"
- push select
- confirm with "value"
- plug back firewire

Computational Model of PD

Posted by Adrian Freed on November 5, 2007

The core language design and scheduling features of PD and Max/MSP are from the same author: Miller Puckette.
http://puredata.info/
They share the same core datatypes, although PD has no length limit on lists?
There are only a few externals that perform computations in separate threads, e.g. [sndfiler], threadlib.
