Abstract
A multimedia controller apparatus provides for computer programmed volume control and summing of audio signals in an enhanced multimedia environment. The apparatus is capable of receiving and processing inputs from a CD-ROM FM synthesizer, general MIDI audio, microphone, PCM sampled sound, and telephony systems. From these inputs, it produces outputs for PCM sampled sound, telephony systems, and stereo line-out. Additionally, it provides for the integration of telephonic support functions into a multimedia system. The multimedia controller apparatus comprises a volume control portion for receiving and controlling the volume of a plurality of analog input signals. The volume controlled input signals are then combined by an aggregation portion. A telephony processing portion is also provided for processing the telephony input signals. Stereo outputs, mono outputs, digital samplable outputs, and telephony outputs can be formed from the combined analog and telephony signals by an output portion. To control the volume control portion, the processing portion, and the output portion, a data control portion is provided which responds to externally generated control data.
