Like busy train stations, digital audio I/O cards today shuttle more incoming and outbound tracks than ever before. Whether you're riding the Toslink

Like busy train stations, digital audio I/O cards today shuttle more incoming and outbound tracks than ever before. Whether you’re riding the Toslink Overland, AES/EBU Bullet Train or Analog XLR Express, there’s a wealth of new cards to choose from when routing tracks into and out of any laptop- or minitower-based station.

If you’re looking for a new I/O card, we know there are a lot of options out there, so to make it easier for you, we’ve put together the following list of new or significantly upgraded I/O card packages released since Winter NAMM ’99. Information on bundled software, hardware and connectors is included, as is data about analog and digital I/O, sampling rate support, synchronization, driver updates, onboard synthesis, DSP effects, expansion options and more.

A few turnkey computer solutions are included here, but the majority of these audio I/O solutions for Mac and PC consist of a PCI computer card; a breakout box or cable bundle; and a collection of mixer, sequencer and/or audio utility software applications. Look for cards with SMPTE and VITC support for film and video work, digital inputs and outputs for lossless audio transfers, and dedicated onboard DSP to help you design the widest and most efficient audio “train station” your computer can handle.

Aardvark’s Aark 24 ($899) is a 24-bit solution for Windows 95/98 users. It offers eight 11/44-inch analog, RCA and Toslink S/PDIF, ADAT optical and word clock I/O connectors. Aark Direct ($425) comes with virtual mixing software, 2×2 11/44-inch and RCA analog and S/PDIF I/O, and an optional AES/EBU interface, all in a single rackspace. Aardvark’s Aark TDIF ($425) includes DSP processing, peak metering and eight channels of 24-bit TDIF audio. The Direct Pro 24/96 ($699) comes with a full complement of PC audio goodies: four XLR mic and four 11/44-inch inputs, six line outs, RCA S/PDIF connectors, three-stage input trim, and DSP effects that include compression, reverb and EQ algorithms.

Users can now plug all their ADAT tracks directly into a Mac or PC with Alesis’ ADAT/EDIT ($399) package. A PCI card, 3-meter ADAT optical cable and customized ADAT audio editing software are included, as are the ADAT/CONNECT audio transfer utility and .WAV, AIFF, ASIO and Sound Manager drivers.

Antex’s StudioCard 2000 Plus ($895) is an improved 24-bit/96kHz version of its now-discontinued StudioCard 2000. It routes two channels of AES/EBU and S/PDIF digital audio in addition to the existing 4×4 analog I/O interface. Bundled with the Plus is Samplitude Project multitracking software from SEK’D; an optional breakout connector box is available for $200.

Among many new Creamware products launched at the recent Frankfurt MusikMesse show were three new I/O card solutions: Luna 2496 DSP ($998), Pulsar II ($1,398) and Scope/SP Studio Pack ($4,695). The Luna is an expandable cross-platform system with an 8-channel rackmounted breakout box and three Analog Devices SHARC DSP chips that can be upgraded to provide more than 100 channels of 24/96 audio I/O. The Pulsar II now boasts S/TDM bus support, ASIO and EASI drivers, and six SHARCs that boost DSP power 50% over the original Pulsar card. Picking up where its predecessor left off is the Scope Studio Pack, a complete recording, synthesis, sampling, effects, mixing and mastering solution for Windows and Mac OS, with 15 SHARC chips that do a lot more than just reduce host CPU load.

Digidesign has released enough I/O options to satisfy any PC- or Mac-based audionaut. The flagship Pro Tools|24 MIXplus System (starting at $9,995), Digi ToolBox XP ($545) and 1622 I/O ($1,595) all debuted since Winter NAMM ’99, and the new 888/24 I/O Audio Interface ($3,695) and Digi 001 ($995) have been big releases, as well. The 888/24 provides eight channels of 24-bit analog and AES/EBU and S/PDIF digital I/O, supports Mac and Windows, and can operate as a stand-alone ADA converter. The entry-level Digi 001 system is plenty powerful, featuring eight analog inputs (two with built-in mic preamps), ADAT optical and coaxial S/PDIF digital I/O, separate monitor and headphone outputs, and it comes bundled with Pro Tools LE and a good collection of DigiRack plug-ins (AudioSuite and RTAS plug-in formats are also supported).

Until Digigram released its first professional PCMCIA audio I/O card, the tiny 11/48-inch micro jack inputs and dearth of PCI slots on laptop computers kept most engineers from taking computer-based recording very seriously. The new VXpocket V.2 ($729) adds linear timecode (LTC) SMPTE support and two balanced mono mic/line inputs to the original VXpocket. Digigram’s new VXpocket 440 ($1,069) goes up to 4×4 balanced XLR mic I/O configurable as four outputs, and the VX222 ($529) sports stereo XLR I/O. All three make professional 24-bit, multichannel, remote laptop recording a reality.

The TDIF 2496 ($495) and CardDeluxe ($595) were two new PC audio solutions released in the past year from Digital Audio Labs. TDIF 2496 Pro, with ASIO and AudioX drivers, supports up to 96kHz sampling rate and 24-bit audio over 16 simultaneous digital I/O channels. CardDeluxe features 24-bit audio over stereo S/PDIF digital and 2×2 11/44-inch analog connectors, includes Active Movie and DirectX plug-in support, and will have Mac CardD drivers in the near future.

Edirol, the exclusive North American distributor of Roland’s computer division products, released two new PC digital I/O options during the past year. The ED U-8 USB Digital Studio ($795) packs a lot into its USB-fed hardware interface: Faders, pan and transport controls are grabably close, there’s three assignable knobs, and users can plug unbalanced XLR mic or Hi-Z guitar into inputs on the front panel. Optical S/PDIF I/O and a powerful onboard DSP engine are included. Edirol’s ED UA-30 Audio Interface ($325) for Windows now also does Mac (an OSX driver is due soon), and it’s the only I/O solution for routing pro-level audio in and out of an Apple iBook.

One new and two updated I/O packages were added to Echo Digital Audio’s family of I/O solutions. The new Mona ($995) sports 4×6 XLR and 11/44-inch I/O jacks, +4 and -10 dB output levels, S/PDIF and ADAT optical digital, four mic preamps with phantom power, word clock support, and comes bundled with Syntrillium’s Cool Edit Pro.
