DigiTorc M Manual
Overview
The
DigiTorc 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, Server 2003 and Vista.
The card has two AES3 inputs and two AES3 outputs, all of which operate independently. An
AES11 external synchronisation input and output is also provided.
The card uses 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 on-board 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 is 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 synchronisation. Multiple cards can be
synchronised together by daisy-chaining the sync inputs and outputs.
