At the Bell Telephone Laboratories (AT&T), Max Mathews does research in computer-generated synthetic sounds.
Synthetic Sound Research
Direct digital synthesis (DDS) and psychoacoustics research would lead to the creation of very particular synthetic sounds. Still today, some of the most notable examples are Jean Claude Risset’s “acoustical illusions”.
The original intention of some of this research was to develop computer-simulations of the voice and other sounds that could be used to automate telephone systems. The results are encountered regularly in everyday life: the 4-1-1 telephone directory assistance (in Canada and the USA) and many answering machines use synthetic voices, “touch tones”, etc. Computers would also be used in this period to analyse or synthesize complex sounds.
