Abstract
A computer audio system and method is disclosed. The system includes an input to receive a digital audio input signal and a splitter to split the digital audio input signal into a plurality of digital audio signals. The system also includes a plurality of digital signal processing software modules corresponding to a detected number of hardware audio interfaces.
Claims20
A system, comprising:
- an input to receive a digital audio input signal;
- a splitter to split the digital audio input signal into a plurality of digital audio signals;
- and
- a plurality of digital signal processing software modules corresponding to a detected number of hardware audio interfaces, the plurality of digital signal processing modules responsive to corresponding ones of the plurality of digital audio signals.
A method, comprising:
- receiving a digital audio input signal;
- detecting a number of hardware interfaces;
- splitting the digital audio input signal into a plurality of digital audio signals corresponding to the detected number of hardware interfaces;
- and
- dynamically creating a number of digital signal processing software modules corresponding to the plurality of digital audio signals.
A system, comprising:
- a processor;
- a memory accessible to the processor;
- a hardware module responsive to the processor, the hardware module including a plurality of hardware interfaces,
- a device driver to control the processor, wherein the device driver includes:
- a splitter to split a received digital audio input signal into a plurality of digital audio signals;
- and
- a plurality of digital signal processing software modules corresponding to a detected number of the plurality of hardware audio interfaces, each of the plurality of digital signal processing modules responsive to one of the plurality of digital audio signals.
The system of claim 20, wherein the plurality of hardware interfaces includes an analog speaker interface, a headphone interface, and a Sony/Philips Digital Interface (SPDIF).
