TremorThe PC today is increasingly used as a multimedia center for gaming, playing movies, and listening to or recording music. As such, PC users now demand far greater audio performance than what onboard solutions are capable of offering. For this reason, VIA has built upon the proven audio technology of its Envy24 line of audio controllers to design the VIA Vinyl Tremor Audio Controller, intended to satisfy the needs and budgets of a new generation of home-PC users while delivering superb audio fidelity.

Benefits of VIA Vinyl Tremor

High audio performance: With up to 24-bit resolution/96kHZ sampling rates for digital input/output and 20-bit/48kHZ analog connections, the VIA Tremor is capable of providing superb audio playback and recording quality to the PC audio enthusiast.

Flexible range of connection options: 6 outbound streams and 2 simultaneous input streams, along with an integrated S/PDIF transmitter, allow for a wide range of connections that can support Dolby Digital/Dolby Digital EX Surround Sound. A direct access general purpose connector allows for easy use of expanded connection boards, and a MIDI port is also provided.

Multiple applications: Applications include gaming, high fidelity home theatre entertainment, music playback and recording.

Easy to integrate: I²S and AC-link input and output for easy connection with many codec or ADC/DAC solutions. Also supports Windows® WDM drivers.
