Auricon 2.2 & 4.1 Manual
Overview
The
Auricon is a professional-quality audio input-output card designed and manufactured in
Australia by Innes Corporation Pty Ltd. It is supplied with DSP software and a Windows WDM
driver to provide full sound card functionality Windows 2000, Windows XP, Windows Server
2003 and Windows Vista. Drivers for under Windows 98, Windows ME and Windows NT version
4 are also available on request.
Two versions of the card are available, the Auricon 2.2 having two stereo outputs and two
stereo inputs, and the Auricon 4.1 having four stereo outputs and one stereo input. The inputs
and outputs can be reconfigured as separate mono channels, giving four inputs and outputs on
the 2.2, and eight outputs and two inputs on the 4.1.
The cards use 24 bit sigma-delta converters which pass data to and from the PC via a 32 bit
bus mastering PCI interface. An onboard 32 bit digital signal processor provides audio buffering,
sampling rate conversion, level adjustment and mixing functions. Sampling rates of 48kHz,
44.1kHz, 32kHz, 24kHz, 22.05kHz, 16kHz, 12kHz, 11.025kHz and 8kHz are supported with 32,
24,16 or 8 bit PCM data and may be set independently for each input and output channel. All
the standard Windows audio APIs are supported, including Wave, DirectSound, DirectShow,
MCI and MIDI playback, as are a variety of audio compression modes via the Windows Audio
Compression Manager or other software compression systems.
