Abstract
The chapter author worked with Manfred R. Schroeder for about 25 years at Bell Telephone Laboratories starting in May 1961. Manfred always inspired this author to look for things one has never seen before. Digital computers were emerging in the 1960s with great promise and we used computers to do many new things: simulation of acoustics of concert halls, studying sound decay in rooms using ray tracing, and producing high-quality speech at low bit rates. This chapter will highlight a few examples. Manfred had been deep in the area of vocoder research at that time, but we started on a new track leading us ultimately to code-excited linear prediction. This set the spark for expanding the use of cell phones worldwide. As a manager, Manfred Schroeder was uncompromising in pushing for scientific excellence resulting in success; Bell Labs had the reputation of being the best.
