The VT8237R Plus South Bridge integrates the high-performance VIA Vinyl
AC'97 controller to enable six-channel audio support and the transfer
of the highest resolution audio possible over the AC'97 standard.
For
the best audio performance, the VIA VT8237R Plus should be combined with
VIA Six-TRAC (VT1616) codec to enable premium quality AC'97 surround
sound. Supporting six-channel outputs with 20-bit resolutions, the
VIA Six-TRAC delivers full 5.1 surround sound to enable theatre-quality
home audio and realistic 3D gaming sound effects on mainstream PC
systems.

The VIA Six-TRAC also features analog mixer circuitry
that integrates stereo enhancement to provide a pleasing
3D surround sound effect for stereo media. Further provisions
in the hardware include the DualMAX? feature that allows
for downmixing of six-channel inputs such as digital
video into four-channel, or even two-channel outputs.
The Six-TRAC also integrates a unique CoolAMP? architectural
design that allows motherboard makers to choose the
best possible amplifier to maximize audio quality and
gain control, while preventing heat from affecting the
Six-TRAC's performance.
The VIA Vinyl Six-TRAC is further enhanced through the VIA Stylus
Audio driver that integrates the latest Sensaura technology for premium
gaming support enabling total audio immersion.
VIA Vinyl Gold Audio
To meet the growing demand for the highest fidelity multi-channel
surround sound, the VT8237R Plus South Bridge can also be coupled with the
PCI based VIA Envy24PT onboard audio controller.
Enabling
24-bit resolution and 96KHz sampling rates for digital
connections, the VIA Envy24PT is the only integrated
PC audio solution that supports up to eight-channel
outputs for improved flyover effects with the latest
Dolby? Digital EX and DTS ES Video soundtracks.
To connect with other devices, the VIA Envy24PT comes equipped with
an integrated S/PDIF transmitter and IEC958 line driver that allows
the easy and accurate transfer of PCM, DTS, and AC3 digital audio
formats to items like stereos and portable audio devices.
For high-resolution eight channel surround sound, the VIA Envy24PT
can be paired with the VIA Six-TRAC codec plus an additional DAC though
an I2S-link, as shown in the diagram below.
