Abstract
A telephone instrument creates spatially simulated sound signals from signals received from a telephone line. The received signals are directed to left and right channels. In each channel, the signals are processed via a direct path, an early reflection path including a finite impulse response filter and a reverberant decay path including all-pass filter. In each channel, the outputs from the three paths are summed with different weights.
