Windows® 7 ASIO Audio Setup Guide for foobar2000

Audio Stream Input/Output, or ASIO, mode ensures your PC sound doesn’t undergo digital signal processing or sample-rate conversion. It is nearly 100% true to its source, and preferred by audiophiles looking for complete fidelity.

Essence products support native Audio Stream Input/Output 2.2 drivers, known as ASIO 2.2., allowing digital signals to bypass Windows audio layers to avoid redundant processing. With easy setup, it allows you to quickly enjoy high fidelity and stable bit-perfect audio.

*ASIO protocol developed by Steinberg Media Technologies GmbH
