Auricon 2.2+ Manual
Overview
The
Auricon 2.2+ is a professional-quality audio input-output card designed and manufactured
in Australia by Innes Corporation. It is supplied with DSP software and a Windows WDM driver
to provide full sound card functionality on Windows 2000, Windows XP, Windows Server 2003,
Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2.
The Auricon 2.2+ has two stereo outputs and two stereo inputs, and is software and pin
compatible with the earlier Auricon 2.2. The inputs and outputs can be reconfigured as separate
mono channels, giving four inputs and outputs. The inputs can be configured for DC or AC
coupling.
The card uses 24-bit 96kHz 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
96kHz, 88.2kHz, 64kHz, 48kHz, 44.1kHz, 32kHz, 24kHz, 22.05kHz and 16kHz are directly
supported with 32-, 24-,16- or 8-bit PCM data and may be set independently for each input and
output channel, while the Windows sampling rate converter will transparently support all other
sampling rates. 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.
The Core Audio API available on Windows Vista and later systems is also supported.
