A soundcard or other audio interface is a requirement for any computer-based home studio setup. Today's computers all come with built in audio hardware, but for true CD quality or better results you will want to upgrade to a higher quality soundcard or audio interface — either a PCI plug-in card (called a "soundcard") or a PCMCIA, USB or FireWire interface.

There are portable digital mixers that can double as a control surface for your computer's digital audio software and provide multiple digital audio and MIDI I/O options. Mackie has announced its new Onyx series mixers, which are high quality analog mixers that can be equipped with a FireWire interface, to route up to 14 channels of digital audio to a computer. This should work great with laptops!

Speaking of laptops, there are several PCMCIA interfaces available for Mac G4 PowerBooks and Windows XP notebooks. Who needs a DAT recorder anymore?


Audio for Games and Internet Multimedia on the Windows PC

While standards for pro audio and music production such as ASIO, VST, KS/WDM and GSIF have reached maturity (and marketplace acceptance), Intel and Microsoft have been more interested in the development of tools for the delivery of 'multimedia' audio for games and the Internet, such as AC '97 and DirectSound. These multimedia standards usually compromise sound quality in the interest of providing compatiblity with low-bandwidth delivery mechanisms such as Macromedia Flash and Microsoft NetMeeting. As a result, many soundcards and audio interfaces for the professional audio market do not support these consumer multimedia standards. If you are producing audio for PC multimedia projects, a professional audio interface probably won't help you much. The Terratec EWX 24/96 is one product that does combine a 24-bit audio interface with DirectSound compatibility.

In the meantime, Apple Computer has incorporated Core Audio into its OS X operating system, making it easier than ever to connect audio hardware to your Mac, from consumer multimedia add-ons to pro audio/MIDI interfaces. No FreeMIDI or OMS needed!


Audio Over USB

There is a wide variety of USB (Universal Serial Bus) audio and MIDI interfaces available for Windows and Macintosh. The original USB spec (USB 1.1) only allows for data throughput speeds of about 1 megabyte per second, which is about the same as an 8X speed CD-ROM drive. Because of this, most USB audio interfaces cannot reliably record multitrack audio into a computer, but most do work well enough for stereo (two channels). USB 2.0 has been introduced with claimed throughput of over 50MB per second. At this point, the only audio interface that takes advantage of the new, faster USB 2.0 is the Edirol UA-1000, but I'm sure it won't be long before there is a wide selection of these things.

Audio Over FireWire

Digidesign, Mark of the Unicorn and M-Audio have introduced new FireWire audio interfaces that allow multichannel recordings to be made using an Apple iMac, eMac or iBook, or any PC or laptop equipped with FireWire ports (such as the Sony VAIO). FireWire (a.k.a. IEEE-1394 or Sony i-Link) has become a popular way of getting multiple channels of digital audio into and out of a fast laptop computer — which has finally made an inexpensive, portable DAW a reality.


COMPATIBILITY ALERT!!

When shopping for an audio interface, you should
always check with the manufacturer(s) to make sure your choice of audio hardware will work with your particular PC or Mac computer – before you plunk down your hard-earned cash and find yourself calling their tech support!

While it's easy to figure out what exact model of Macintosh you have (it's written right on the back of the case), PC users will need to identify the CPU installed and the core logic chipset in the computer's mainboard (motherboard). There are many perfectly fine audio interfaces and soundcards that are not compatible with certain models of computers. Here are a few I know about from first hand experience or bulletins published by manufacturers on their websites:



NEWS ON DISCONTINUED OR DEFUNCT PRODUCTS

The musical equipment business is as cutthroat as any other (more than most!). There are always some companies that will fail or pull out of the audio-for-PC field, or have to completely revamp their product lines. You can find great 'fire sale' deals on discontinued products, but one of these is probably only a good choice as a short-term solution for older Windows 98 or MacOS 9 computers (you can forget about future support for most of these products).



The following is a brief and admittedly incomplete list of audio interfaces and soundcards for musicians (not PC games or Internet multimedia). This list is for reference purposes only — please don't take these brief descriptions as endorsements or recommendations.

The products described are organized into five categories grouped by price, from least to most expensive. To find out more about a particular product, click on the manufacturer's name. This will take you to their website.

This list is not exhaustive, as I can't possibly keep up with all the new products flooding the market these days. If you know of a great soundcard or audio interface that you think should be included on this list, please drop me an e-mail.



Category 1: Low Budget / Beginner Level ($100 or less)

On the low end, these typical 'multimedia' soundcards for everyday computer audio use can also be pressed into service as a basic audio interface for your home studio computer. The microphone input will be a monaural (one-channel) 1/8" phone-jack ("mini-jack"), usually with 1.5V to 5V of phantom power. Neither the jack nor the voltage are suitable for use with professional microphones. If you are using a 'multimedia soundcard' I recommend using a small mixing board for your microphones, instruments and other sources and sending the output of the mixer to the LINE IN on your soundcard.

Also, bear in mind that 'multimedia' soundcards are designed for playing back audio from computer games and DVD movies, or for general "business audio" use. They don't often work very well for recording, mixing and playing back high fidelity audio for music production.



Category 2: Mid Budget ($125 to $350)

Here are some of the least expensive semi-pro ("pro-sumer") audio cards and interfaces for computers.

If you are planning to record using professional microphones, you will need to add a suitable microphone preamp (such as those from PreSonus, Bellari, ART, etc.) or a good quality mixing board (such as those from Mackie, Behringer, Allen & Heath, Soundcraft, etc.). I usually recommend the mixing board option because it will give you more flexibility in routing inputs and outputs and patching in effects boxes.

Here are some of the least expensive semi-pro ("pro-sumer") audio cards and interfaces for computers.








 


Category 3: Low-End Pro Level ($350 to $800)

While some of these more professional interfaces will have built in mic preamps with +48V phantom power and XLR inputs, others have line-level inputs only.

Those products which come equipped with XLR microphone inputs with phantom power are designed to function as close to a complete 'studio in a box' as possible. These products usually include a mixer interface built into their driver software so that the computer takes the place of the mixing board in your studio. Others integrate so tightly with your music software of choice (Cubase, Logic, Cakewalk, etc.) that they accomplish pretty much the same thing.

















Windows 98/Me/NT/2000/XP drivers are available (including support for multi-processor WinNT/2000/XP Pro systems), along with ASIO 2.0 drivers for both Win98/Me and Windows NT/2000/XP. MacOS (ASIO 2), Mac OS X, Linux and BeOS drivers are also available.

Eight unbalanced, 24-bit 48kHz analog line-level audio inputs can be added using the AEB8-I daughterboard (~$200). Combine an RME DIGI96/8 PAD with an AEB8-I and you'll have a rock-solid 8-in/2-out hard disk recording setup complete with stereo S/PDIF and AES/EBU, and 8-channel ADAT digital I/O, for less than $600!

Optional Word Clock input and output is available for syncing with external digital audio equipment is available (add ~$125).

RME's Windows drivers allow up to three DIGI96/8 cards to share the same IRQ (this has to be supported by the motherboard's BIOS — both ASUS and Gigabyte motherboards support this). Additional DIGI96/8 cards can be synchronized to a single card acting as the clock 'master', and if the Word Clock option is installed, the whole 'network' (all digital recorders in the studio) can be synchronized to the DIGI96/8 'master.'

I've never seen a bad review of an RME Audio product, and I've had very good experiences using the DIGI96/8 PAD (in a Windows NT 4.0/Celeron system and in a Windows 2000/Athlon XP system). You won't find the impressive features of some of its competitors—the RME DIGI96/8 PAD has no mic pre's, MIDI I/O, ADAT sync or balanced analog inputs/outputs—but you will find that it sounds great, has rock-solid drivers and will always let you get your work done. My DIGI96/8 PAD has performed like a champ in every PC in which I've used it.





 


Category 4: For Laptops Only












 


Category 5: Professional Level

These products are designed for use in professional studios. The computer-based products are designed to be expandable with external interfaces and additional DSP, and to connect to the other digital audio devices that are mormally found in a full-blown recording studio. The stand-alone products are designed to be used as a full-function, portable "studio in a box."
