With the evolution of the Multimedia PC, audio has become one of the essential features of the personal computer. Whether gaming, playing movies, or recording your favorite song, the VIA Vinyl Envy24GT Audio Controller provides the inputs and outputs for the complete sound experience.

Benefits of VIA Vinyl Envy24GT

Extremely high audio performance: With 24 bit performance and 192kHz sampling rates the VIA Envy24GT provides the highest audio playback and recording quality available to the PC audio enthusiast.

Wide range of connection options: 6 outbound streams and 4 simultaneous input streams allow for a wide connection range that can fully support 5.1 surround sound audio. A direct access general purpose connector allows for easy use of expanded connection boards.

Multiple applications: Applications for the VIA Envy24GT include high fidelity home theatre entertainment, cost effective multi-track audio, while its extremely high performance enables more technical applications such as PC-based data acquisition.

Easy to integrate: Supporting I²S and AC-link inputs and outputs or alternatively AC-link support the VIA Envy24GT can be easily combined with a wide range of codec or ADC/DAC solutions.


The VIA Vinyl Envy24GT is a versatile 24-bit multi-channel audio controller that enables studio level audio performance. Supporting up to 192kHz sampling rates the VIA Envy24GT has the highest audio recording quality in its class giving home studio musicians 6 outbound and 4 simultaneous inbound streams with all paths passing as 24-bit audio, “as is”, unaltered, bit per bit accurate.

To maintain a full digital path for PCM or compressed audio formats, the Envy2GT integrates a complete S/PDIF transmitter for connection to digital audio interfaces. For connection to keyboards and sound devices an independent MIDI UART is provided. The VIA EnvyGT also includes a direct access 23-pin GPIO that brings flexibility for multi-purpose connections uses such as the integration of break-out boxes that allow for enhanced connection options.

The VIA Envy24GT can be combined with professional grade I²S converters, S/PDIF receivers, or multi-channel out AC-link codecs, such as the VIA Eight-TRAC Audio Codec.
