I was reading an article this morning about how to select a sound card for your laptop if you plan to do pro-sounding recording on the move. For the most part though, when you say “sound card” in relation to professional sounding recording, what you’re really saying is “audio interface,” or external sound card. In fact, most interface units aren’t “cards” at all, but usually boxes that plug into the laptop either via USB or Firewire (more USB these days). Anyway, the more I read through the article, the more I realized that for the most part, any interface you choose for your laptop would also be great for your regular non-mobile computer. So the questions you ask yourself about mobile recording interfaces are largely the same as you’d ask for your home studio recording interface. These days, unless you plan to become a commercial recording studio, the interface units for a computer based home studio will be small boxes, i.e. the same as would be appropriate for mobile recording.
So what are the questions you should be asking? According to the article in question, they are:
1. Is portability a concern?
2. How many inputs and outputs do yo need? In other words, will you need to record more than one thing at a time – a guitar and voice simultaneously, for example?
3. Will you be recording with a microphone or using “outboard gear” like a MIDI keyboard.
4. Do bit-depth and sampling frequency really matter? This one I really like the answer to, because it is definitely what I believe as well. That is basically that though it makes a technical/objective difference, a vast majority of people won’t be able to tell the difference between some of the more affordable interface units and the super expensive ones if the main difference is bit-depth.
5. What other accessories might you need? This refers to speakers (notoriously un-mobile), headphones, mics, cables etc.
Here are a few examples of good mobile interface units. All of these have phantom power, by the way – something you need if recording with a condenser microphone, and connect to a USB port.
The cEntrance MicPort Pro
The cEntrance Mic Port Pro is really the ultimate in portable interfaces. It records very high-quality audio, plugs right into a USB port and has a headphone jack. See my review of it here (includes audio samples): https://www.homebrewaudio.com/review-of-the-centrance-micport-pro-audio-interface/. $149.95.
The M-Audio Mobile Pre
The M-Audio Mobile Pre is lightweight, has two combo (mic or line-level) inputs, and is definitely a great-sounding interface. $111.71.
Focusrite Saffire 6 USB
Great quality from a famous name in audio for a great price. It has 2 combo inputs with the same preamps as all the other Focusrite Saffire series interface units. $174.99.
M-Audio Fast Track
And of course, the M-Audio Fast Track which is very portable, has a mic and an instrument input, and costs just $99.99.
Of course there are dozens more out there.
