The emergence of software-based digital tools for audio made an impact on the design of hardware controllers. The tactile aspect of working with audio tools was no longer a given, resulting in a steadily growing range of available hardware controllers meant for use with various audio software. Creative solutions vary from simple MIDI-controllers such as the Behringer BCR2000, generic music production workstation controllers like the Mackie control pro series and the Euphonix MC Control, to... read more

A program that provides a general way to efficiently allocate and use memory inside a realtime audio thread without having to manually free it later. Go to Kjetil Matheussen’s web page for the... read more

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... read more

Description Ceres performs spectral analyses of sounds, and presents these analyses as a sonogram where time is represented along the x-axis, and frequency along the y-axis. Amplitude is shown as a color. Various operations can then be performed in the frequency domain, such as pitch shift, spectrum shift, time-stretch, filtration, removal of tones selected from either amplitude or  by random, aligning partials according musical scales, etc. The parameters may change over time. Analyzed data... read more

Pure tuning is a tuning method not based on compromises in the intervals between the tones. In order to play a keyboard instrument with pure tuning, the Norwegian musicologist and composer Eivind Groven developed an automatic switching system, which served as the basis for many instruments that were built for him. The system still exists at the Groven Institute for Pure Tuning at Ekeberg in Oslo. The system has been modernized by NOTAM in collaboration with musicologist David Loberg Code. NOTAM... read more

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... read more

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... read more

DSP02 is a composition and audio processing software for children that can be used on all computers. Description DSP02 features a mixer where sounds are put together, and various small programs for sound editing and audio processing. These programs are opened in the mixer window, pictured below. The program is uploaded on a website which includes user guides, tutorials, music examples and assignments for use in classrooms and workshops. DSP02 screenshot How is the program useful? The program... read more

Bio is an interactive analysis program for SGI and Linux machines, which shows sonograms, spectrograms, oscillograms, pitch tracking, spectral gravity and noise content. Description Bio can perform spectral analyses of sound of any length. The user can zoom in and out in the sonogram, and extract accurate amplitude and frequency values (the latter with the aid of a phase vocoder) by clicking in the image. The program also features an oscillosgram, as in a sound editor, a pitch tracker and a... read more
