Iain Mott

Iain Mott is a sound artist and a lecturer (professor adjunto) in the area of voice and performance in the Departamento de Artes Cênicas (theatre arts), Universidade de Brasilia. His sound installations are characterised by high levels of audience participation and novel approaches to interactivity. He has exhibited widely in Australia and at shows including the Ars Electronica Festival in Linz, Emoção Art.ficial in São Paulo and the Dashanzi International Art Festival and Multimedia Art Asia Pacific (MAAP) in Beijing. His most recent installation with Simone Reis O Espelho was exhibited at the Centro Cultural Banco do Brasil (CCBB) in Brasilia in the second half of 2012. Iain has received numerous awards and grants and has successfully managed innovative projects for almost 20 years. His GPS-based project Sound Mapping was awarded an Honorary Mention in the 1998 Prix Ars Electronica. In 2005 he was awarded an Australia China Council Arts Fellowship to work with the Beijing arts company the Long March Project. His work Zhong Shuo was created as part of the fellowship in collaboration with Chinese artists and was given 3rd prize in the UNESCO Digital Art Awards. The project has in addition been selected by MAAP for two further installations in Shanghai and Brisbane in 2006. Iain was artist in residence at the CSIRO Mathematical and Information Sciences in Canberra for 12 months in 1999/2000. The notion of collaboration between artist and audience has ongoing importance in Iain's work. His PhD from the University of Wollongong was supervised by Greg Schiemer and is entitled Sound Installation and Self-listening.

The script and other configurations detailed on this page convert mono files generated by a Tascam DR-680 with a Core Sound Tetramic soundfield microphone to B-format 4-channel wav files. It requires that the Tascam DR-680 is configured to save recordings as mono sound files on channels 1, 2, 3 & 4 and that these channel numbers match the corresponding capsules on the Tetramic. The script also requires that Tetramic calibration files are installed (see below) and the additional installation of the following programs by Fons Adriaensen

tetraproc-0.8.2.tar.bz2 

jconvolver-0.9.2.tar.bz2 (includes the necessary utility "makemulti")

Fons Adriaensen provides a free calibration service for Tetramics which generates calibration files specific to each microphone based on data provided with the microphone on purchase. See"TetraProc / TetraCal" and "Calibration service for Core Sound's TetraMic" on this page for further information.

Run the script in a directory containing the mono files. Change paths and configuration filenames in the script as necessary. Use the command line argument --elf to enable extended low frequency response in the b-format output (-3dB at 40Hz) or none to use the default roll-off at 80Hz.

The B-format script is contained in the attachment "mono2bformat.zip" below. Alternatively, copy the following code:

#!/bin/bash

#Converts dated mono files generated by a Tascam DR-680 with a Coresound Tetramic ambisonic microphone to B-format 4-channel wav files. Run this script in directory containing the mono files. Change paths as necessary. Use the command line argument --elf to enable extended low frequency response in the b-format output (-3dB at 40Hz) or none to use the default roll-off at 80Hz.
