Abstract

An audio circuit for a computer includes a bidirectional modem connection, a microphone input, first and second audio output channels, and an audio synthesizing circuit arranged to produce first and second synthesized audio channels. In a first mode of operation the first synthesized audio channel is applied to the first audio output channel and the second synthesized audio channel is applied to the second audio output channel. In a second mode of operation the first and second synthesized audio channels are combined into a monotonic signal and applied to the second audio output channel, and audio signals from the bidirectional modem connection are applied to the first audio output channel.
