SoundMagic Spectral is a FREEWARE suite of 24 Audio Unit plug-ins that implement real-time spectral processing of sound. This groundbreaking set of effects give you unprecedented control and creativity in the processing of audio, whether from static audio files or live audio streams. SoundMagic Spectral builds on the work of the OS 9 software known as SoundMagic DSP, and takes it to even more exotic sonic realms.

This is a little Javascript program that calculates the frequencies of partials in a harmonic series. You can also specify a stretch on the harmonics.

v1.1 ©2010 Michael Norris

This is a little Javascript program that calculates the frequencies of partials in a harmonic series, and returns the results in a tab-delimited list ready for pasting into Excel. A [+] or [-] after a note name indicates a microtonal deviation.

This is a little Javascript program that contains about 800 different melodic modes (equal-tempered only), categorized into different types.

v1.0b12 ©2006 Michael Norris

This is a little Javascript program that lets you choose a pitch-class set, and then returns a bunch of information about it, primarily drawn from Jenny McLeod's and Peter Schat's Tone Clock theory. Information returned includes the Intervallic Prime Form (IPF), the Forte Name, and the "dissonance". Much reference is made to Tone Clock theory, drawn from the IPF tables in Jenny McLeod’s “Chromatic Maps”* (based on Peter Schat’s work). At the bottom of this page is a glossary explaining (some) of the terminology. One day I'll get round to explaining everything... :-)

This is a little Javascript program to produce a list of spectral peaks and their tunings given an input BPF file from Audiosculpt .

v1.0 ©2008 Michael Norris

This is a little Javascript program that determines every possible pitch tessellation for any-sized IPF within any-sized equal-tempered subdivision of the octave

v1.0 ©2002 Michael Norris

This is a little Javascript program to convert an equal-tempered note name and octave into a frequency.
