Overview

The Digitorc M is a professional-quality AES3 (formerly AES/EBU) 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 under Windows 2000, XP, Vista, Windows 7, Windows 8, Server 2003, Server 2008, Server 2008R2 and Server 2012. It also is supplied with an ASIO driver which will be used by the card automatically should the card be used in a software application that requires an ASIO driver for multi-track synchronization.

The card has two AES3 inputs and two AES3 outputs, all of which operate independently. An AES11 external synchronization input and output is also provided.

The cards use 24-bit AES3 transceivers, 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. Output physical sampling rates of 96kHz, 48kHz or 44.1kHz are available, with onboard sampling rate conversion for the full range of software sampling rates and bit depths. The AES3 inputs will accept any rate from 32kHz to 96kHz and are automatically converted to whatever software recording rate and bit-depth are requested. The Windows Wave, MCI, DirectSound and DirectShow API’s are supported, as are a variety of audio compression modes via the Windows Audio Compression Manager or other software compression systems. The ASIO API is also supported for multi-channel recording and playback.

The AES11 sync input will lock the card to an external AES3 audio source at 44.1kHz, 48kHz or 96kHz, providing both bit rate and L/R timing synchronization. Multiple cards can be synchronized together by daisy-chaining the sync inputs and outputs.
