Kjetil Matheussen will present a paper for the Linux Audio Conference 2011. The paper presents a new compiler called Poing Impératif. Poing Impératif extends Faust with common features from imperative and object oriented languages. Imperative and object oriented features make it easier to start using Faust without having to immediately start thinking in fully functional terms. Furthermore, imperative and object oriented features may enable semi-automatic translation of imperative and...

With Hurtigmikseren you can mix audio files on the fly online. The result can be saved on your computer, sent as an audio files, transferred to your iPod or mobile phone, or uploaded here on musikkverksted.no Hurtigmikseren was programmed by Kjetil Matheussen from NOTAM on request from musikkverksted.no. The user interface was designed by Stig Nøst Dahl Andersen. How to get started with Hurtigmikseren DEMO (Norwegian) USER GUIDE (Norwegian) The user guide applies to the standard version. With...

Mammut is a program for Linux, Windows Mac OS X that does audio processing in the frequency domain. Description Mammut does an FFT of the whole sound (no windows). Various operations can subsequently be done in the frequency domain, such as unlinear stretching of the spectrum, sprectrum shifting, etc. How is the program useful? Doing a giant FFT of the entire sound, as opposed to splitting the sound up into short windows, is unusual. Such a method implies that time-related parameters are...

Description What is Snd-rt, and where you can find it? SND is a popular audio editing and signal processing tool that was originally written by Bill Schottstaedt at CCRMA, Stanford University. The program is written in Lisp, and is easily integrated with other Lisp software from CCRMA, such as: Common Lisp Music Common Music Notation Common Music Snd-rt is an extension of SND which consists of two parts: - The RT Engine – a program that allows signal processing in real time. - The RT...
