Various Ways to Interface Your Instrument to Your Computer


If you are obsessed with home recording and have spent a lot of time and money figuring out the best way to connect microphones and guitars to the  computer over the years, here are the routes and what worked best.

Platform


We have chosen to go with the Mac platform, just because, and software "GarageBand" and as their recording capabilities are somewhat satisfactory.

Straight Line-In w/ Radio Shack Adapter


The first thing tried was to use the built-in line-in on Mac, which is a 1/8-inch female stereo port. So, a 1/4 inch to 1/8 inch adapter from Radio Shack is attempted. This was the worst way to interface the guitar to the computer. The part from Radio Shack didn't fit the instrument cable just right, it causes undue wear on the Mac's port, and the sound was super tinny.

iMic


The iMic is basically the same as the Radio Shack adapter, only it’s got a short cable on it and it fit the instrument cable better. What we get is still a pretty tinny sound.

M-Audio Fastrack USB Audio Interface


The first fruits of success sit with this $99 audio interface. Essentially it takes your guitar's or microphone's analog signal and turns it into a digital one. It sends the digital data via USB to your recording software, and voila!

There was still a problem with buzzing and feedback, however.

Also borrowing a friend's mixer which would allow one to do some mixing and balancing, and pretty soon we were making stereo recordings. It sounded pretty good, but the interference increased. There were too many connections and cables and opportunities for signal loss and corruption.

Alesis 8-Channel USB Mixer


This is the solution that has worked best for a small home-grown budget while getting virtual recording studio quality. This mixer was around $200 but acts as both a regular analog mixer and a USB interface (both parts of which can be used independently of the other). This mixer/USB interface removes some of the seams of the rig, allowing for purer sounding, higher quality recordings. The mixer also features 100 different pre-amp effects.

So, essentially, the signal goes from the guitar, through a cable to my USB mixer, through the USB cable straight to the computer. There are very few analog connections involved.

Behringer iAXE 393


There is one more option that has even less analog connections. The Behringer iAXE 393 has a USB port right on it, allowing you to plug it straight into your computer digitally. This is quite an incredible idea, allowing seamless digital recording. Hopefully, more guitar companies will jump in and add their own USB versions of their guitars.

In testing the iAXE, although the action is a little high, the guitar sounds great, pumping data straight into Garageband.
