Computer Audio Hardware
Here we look at dedicated audio hardware for the computer. These vary from one recording source to as many as 10 simulantious tracks. It should be noted and remembered that professional music recorded up until 1960 was generally done on one single track! Also, by using software such as n-Track, Data Becker or Cakewalk you can mix and master anywhere from 8 tracks to 128 total tracks of audio, depending on how much memory you system has, the power of the CPU and the speed of your hard drive!
In picking a connection for your needs consider the following: software compatibility, not every piece of hardware might work with software such as Cube Base or Cakewalk for multi-track recording.
Connections. There are all sorts of connectors and connecting impedances! Pro standard is XLR at +4dBu (1.35 volts) with a secondary standard of ¼' ring tipped balance connectors, usually at the same rating. Amateur equipment (home stereo and tape decks) use RCA connectors at –10 dbv (0.775 volts) with a secondary connection of either ¼' phono plug or the 1/8' stereo mini plug (your typical "Walkman" headphone chord adapter size).
There are also digital connections, including the optical cable, the S/PDIF. There is also the A-DAT format and the Tascam D-88 R-DAT format, plus the Apple FireWire.
Connections to the computer include: USB (only on newer machines, that little rectangular input where all sorts of gismos can be daisy chained today), PCI (the standard card slot for both newer Macs and PCs), FireWire (created by Apple for video transfers and only found on selected computers or selected video and audio cards) and rarely found today is the old PC ISA slot.
No one card or box we looked at supported everything, so plan your connections carefully as you never can tell if a FireWire or D-88 R-DAT might come your way!
References to "Break out" cords and boxes is a provision from which you can plug in connections using a long external cord or a box of connectors wired to the computer, which makes connecting things much easier!
Phantom power is a 48 volt hot tip XLR connection used for some condenser michrophones such as the C-414 or U-47. It can be a plus for those working with micrphones priced over $500.
Rack space refers to an industry standard audio or video rack for holding equipment. This is rectangle made of heavy, painted steel bars that have holes drilled to mount equipment such as amplifers, reverbs and limiters (see picture at left, courtesy Downwitit Recording, Indianapolis, IN, racks of equipment are seen in the lower right corner). A single rack space is generally 1" in height.
These items let you connect analog sound sources to your computer via the USB connection port. While they generally offer no software, the advantage is that with the USB connection you can daisy chain a lot of devices, which is good for people with no open slots or those who have a problem installing cards. Also good for use with laptop computers.
With these interfaces you can connect microphones, guitars or mix down 2 track recordings from an external multi-track recorder.

Sixteen-bit/44.1kHz AD/DA converter
No adapter needed, powered through the USB port
Stereo RCA plugs in and out
Works with MME in Windows and Sound Manager on Mac systems
Edirol UA-3A USB/RCA/1/4'/1/8' In and Out Capture.
16-bit/32, 44.1, or 48kHz A/D conversion

Works with Windows 98 Pentium II 233 or later and Mac OS 9.0.4 or later
One fader seems to control both the guitar and mic, while the other fader controls the RCA inputs, therefore we assume you must switch from one to the other for the recording process. Outputs are RCA or optical.
24-bit USB audio interface. 1/4" EFR guitar hi-Z input.Stereo 1/4" line in/out.1/4" mic input.Convenient 1/4" headphone output. Solid steel construction. Knobs and sliders for perfect level control. Self-powered from USB.Includes Cakewalk Guitar Tracks (PC) and Metro SE (Mac).
Edirol UA-5A USB/XLR Capture.
No specific details on this item. It has head phone monitor out (which can also probably work as a record out with proper padding) with a level control. It has 48 V phantom power on at least one of the XLRs and at least one of the XLRs can be switched from Hi-Z to Lo-Z. It looks to use like there are ¼' inputs inside the XLR connectors (which is common on many high end computer connections) but we can't verify this fact. No specifics on outputs, except for the headphone monitor jack which is ¼' stereo.
This is a new item and is Mac/PC compatible.
M Audio Quattro USB/MIDI/1/4' In and Out Capture.
24-bit/96kHz, through your laptop, iMac USB port. Pristine A/D-D/A converters. Zero-latency direct monitoring for simple recording and dubbing, 4 balanced 1/4" TRS connectors for both In and Out (a total of 8 connections), and selectable in and out levels to accommodate different instruments. MIDI In and MIDI Out connectors.
This unit holds just about any connection the average musician might need.
Roland UA-100 USB/1/4'/RCA/MIDI In and Out Capture.
Had dedicated Guitar or Mic input and a second mic input. Both are ¼'. There are also RCA input and outputs (no ¼' out) plus 2 Midi in and 2 Midi out. Boss multi-effects processor. Headphone output.
Emagic EM 2/6 USB In and Out Capture. List $400.00
This is a specialty item that doesn't hold much benefit for the novice or rank and file musician, but this might have potential for monitor playback in studios. It was designed for 6 channel surround sound playback and stereo input, but it might be possible to use the six sends to feed different musicians a different level of headphone mix. Other than this potential, which needs to be explored with care by the potential buyer (you should look at the unit and try it out to see if it will work for this need).
This may also work for studios to deliver the same stereo feed to remote monitor systems, such as inside the studio, inside a monitoring room and inside the control room.
It also holds potential for presentations.
SoundBlaster Live Platinum 5.1
Modestly priced this card is probably entry level for the novice musician and Midi performer. It comes with some nice software. The connectors are metal 1/8' mini-plugs which are, unfortunately, too close together to accommodate a lot of connecting cords! I had to take a knife and bevel off side of my connectors to make them all fit. Music composition software is included. Uses EMU10K1 technology.
It would behoove the makers of sound cards to space there connectors further apart!
This one also has a direct digital connects. It includes a wave table sounds and synthesizer generated audio.
The SoundBlaster Live and Live Value
Lower priced versions have color coded connectors and are missing all of the good software. This card often comes with most integrated or low end systems.
SoundBlaster Audigy Platinum EX

Supports 24 simultaneous full duplex tracks of recording. No MIDI! Uses PCI interface and the box fits a one rack space.
The IEEE digital FireWire interfaced created by Apple is vastly become a defacto standard, largely because of digital video, but audio technology has also caught on with the massive throughput you can obtain through a single connection!
All your multi-track audio information is digitized and sent out in bulk packet via the FireWire cord, where it is reassembled inside the computer via software.
