HiFi Cable functions as a virtual audio driver providing seamless audio routing between playback and recording devices. It supports multiple audio driver protocols including MME, DX, WDM, KS, and WASAPI, enabling audio signals to be transferred effortlessly from the cable input to the cable output. This virtual connection facilitates flexible audio management for various applications and systems without the need for physical cables.

An integral feature of HiFi Cable is its ASIO Bridge, which extends compatibility by allowing audio streams to be routed through ASIO devices. This bridge enables any audio application, including video games and media players, to utilize ASIO drivers via their native Windows audio interfaces. Users can distribute multichannel audio, such as 6 or 8 channel outputs from DVDs, to professional audio devices that typically require ASIO support, enhancing playback quality and channel management.

HiFi Cable supports a wide range of sample rates from 8 kHz up to 384 kHz with 16 or 24-bit resolution, ensuring bit-perfect audio transmission across up to eight channels. The ASIO Bridge is user-friendly, running quietly in the system tray with options for automatic startup and multichannel assignment, maximizing workflow efficiency. Available as donationware, HiFi Cable and its ASIO Bridge offer a powerful and flexible solution for advanced audio routing needs.
