The Basics

Here's the basics of what you need to know. Any additional advice I might give I'll add after this article, so be sure to check every once in a while for new ideas. Also, feel free to contact me with any questions and I'll try to answer them directly as well as post them here.

Without further ado...

I'm a musician, a songwriter and an audio engineer. That's what I do for a living. Well, mostly the audio engineering part. So I've posted this (in numerous places) to help people who are trying to set up a home studio for either music or voiceover work. I also mention my musical project in the article which you can find more about here.

Anyway, I hope this helps!

Home Recording

My brother(s) and I are all audio engineers as well as musicians and writers, and I am frequently asked about setting up a home recording rig. Of course, the side of the industry I work in is predominantly voiceover, but during a recent Slashdot conversation the topic came up (on the music side of things) and I decided to post my suggestion for a very inexpensive but effective basic recording setup. Some have suggested that I charge for such advice (I live in Los Angeles, where we invoice people because we breathed on them) but I think for something this basic that's ridiculous.

Of course, if you want a more detailed consultation or for me to come set it up for you, I'll be happy to take your money.

The first section is for musicians, and the second for voiceover artists.

For Musicians

I think the first rule of recording outside of a studio (speaking as an audio engineer who works in a studio) is to accept that your recordings will not sound like they were made in a studio. I think the second rule is there's nothing wrong with that. Though the majority of great recordings thus far have been made in a studio environment, I am periodically surprised by recordings made in less than stellar conditions that sound fantastic. This is a subjective art. You probably won't be making Steely Dan or Alan Parsons records, but Jason Falkner, Jack White and even Bruce Springsteen have made some great sounding stuff under less than ideal recording conditions and environments.

Here's some starter ideas.

Software: REAPER = $50 (Free until you can afford to pay for it, basically.) Alternatively, if you own a Mac, just use GarageBand. It's simple, powerful and built into the iLife package that comes with most Macs, as I recall.
Interface: M-Audio FastTrack USB = about $100
Microphone: Shure SM58 = about $100. If you don't have any room treatment (loosely "soundproofing") then this mic will be your friend. It sounds pretty good on most things from voice to instruments, too.
Subscription: TapeOp = Free one year subscription (trust me...you'll want this)
Don't forget a couple cables for your mic and instrument if necessary. Plug in your instrument of choice and have fun. Experiment with where you put the mic until you like the sound of it (and DON'T LET YOUR METERS GO INTO THE RED!) Pay close attention to how your choice affects the sound of the overall mix as you add tracks. Don't be afraid to experiment with software, sound or equipment. Remember, though there are good techniques, the only right techniques are the ones that sound good to you.

Also get onboard a good site like Gearslutz and read, ask and engage.

Most importantly, use your ears, pay attention, try to mimic things you like from other people's recordings and LEARN from doing it. We're all geeks, damnit. Isn't that how we learn to do everything?

That'll be 5 cents, please.

For Voiceover Artists

You're just starting out and you need a rig to practice with. Or you've decided to make your own demo (I don't recommend doing this from home, but if you have the time, the resources for sound effects and music without violating copyright laws, and the ambition to do a lot of research on what a good demo sounds like, why not take a stab at it?) Or your agent told you it's time to start doing auditions from the comfort of your domicile.

Don't panic. It's not rocket science.

Most of the musicians advice above also applies to you, although you might want to do a few things differently. If you're really on a budget, please read all the way through, because I have an inexpensive suggestion for you, too. Here are some alternative suggestions.
Software: Audacity = Free to download, but don't forget to follow the instructions on the site for exporting MP3 files. Your client may not be too keen on waiting for much larger WAV files to download from their inbox. Audacity is a bit easier to use than REAPER, and though a bit less powerful, should be more than enough for doing voiceover work.
Interface: M-Audio FastTrack USB = about $100. Look, they just work. Alternatively, any device in this price range that has an XLR connection (the 3 pin cable) and a built in Mic Preamp (for turning the level of your mic up) will probably do the job. Most of the time, of course, the more you spend on a Preamp, the cleaner it usually sounds. Don't get bogged down in special features, though. Less bells and whistles on a device usually leaves you with a cleaner sound, and in voiceover you want it clean. Also make sure it has a USB connection (or Firewire if you have it) to get it into your computer.
Microphone: I'm gonna recommend you spend just a little more money on this than the musician would, cuz the SM57, though adequate, is probably not gonna treat your voice the way you want it to for speech. There are two types of mics to concern yourself with here. Dynamic microphones which tend to be less sensitive and don't require phantom power, and Condenser microphones which will pick up most everything in the room and require that your preamp provide +48V phantom power (most do...just look for the button on the preamp/interface that says +48V...it sends the power right up the microphone cable.) If your room is "noisy" or "boomy" (and most bedrooms and living rooms are), consider a dynamic mic. If you've got a closet packed full of clothes, or plan to do some room treatment (loosely "soundproofing"...see below), consider going with the condenser, which is more likely to pick up the nuances in your voice. All the mics I'm about to list are great, especially for the price.
SM7B (Dynamic) = about $350. A solid, all round mic that is good at keeping out electronic noise (buzzes) from Monitors, Computers, and other things you might have plugged in nearby.
RE-20 (Dynamic) = about $400. Guys with low or very textured voices will love this mic. Both this and the SM7B are used a lot in Broadcast applications, so if you've heard people on the radio, you've probably heard one or both of these mics.
AT4040 (Condenser) = about $300. I consider this to be the bottom end of the professional condenser mics (which is a compliment...high end professional condensers cost thousands of dollars.) It's clean, clear and neutral, and I would take it in a heartbeat over many of the mics that cost only slightly less.
Bluebird (Condenser) = about $350. This is a wonderfully smooth, rich mic for the cost, and adds a little extra presence for the ladies. Be careful if you have problems with sibiliance or mouth noise, though, as this mic does boost the higher frequencies just a little bit.
Of course, you can go with some of the mics less expensive than these, but (in my experience) you may have to deal with them having too much high end (showing off sibilance, breath and mouth noise) or boosting too much low frequency (boomy or muddy sounds.) Your results may vary.

You might also consider buying a compressor, which will help tame and smooth the levels on your voice. Be sure you have a place for it in your signal chain. If you have a USB interface, for example, make sure it has "inserts" on it for you to add the compressor. Alternatively, you can use software compression (usually after you've recorded), but if your meters peaked in the red, you'll have to do the take again. External (hardware) compressors help to keep that from happening. Compressors range anywhere in price from $100 all the way up into the stratosphere, and usually the more expensive ones (remember you only need a one or two channel compressor...not a rack of eight) are more "transparent" on your voice (you really don't want to hear a compressor working.) That said, I'm rather fond of the Really Nice Compressor when it comes to inexpensive but transparent audio. Runs about $200.

Let me just reiterate. DON'T LET YOUR METERS GO INTO THE RED! In fact, if your levels peak somewhere between -12dB to -6dB, you're fine. A compressor (whether in your software program or externally) will help make that more consistent (and you will hear the difference.) If you have a compressor, try a ratio of about 3 to 1 (3:1), a fast attack of just a few milliseconds (if you have that option), and adjust your threshold control to around -10dB to -20dB. Turn up your preamp volume (on your interface) until your voice shows (on average) about 3dB to 6dB of Gain Reduction on your compressor's meters. If it's too quiet, you can bump the output level of your compressor up a couple dB, but not too much.

About "soundproofing", or more accurately, room treatment. Acoustics is complex science. It becomes expensive very quickly to try and treat a room for problem frequencies and sounds. That said, I can offer just a little advice.
Parallel surfaces are bad. For soundwaves they act just like a mirror, bouncing them back and forth, back and forth, until those soundwaves finally run out of juice. Try to place the mic somewhere that isn't between parallel walls (or place it somewhere you have a bookshelf, clothing, or some other surface that can break up the soundwaves, reflecting them in different directions, as well as absorbing some of them.) Parallel surfaces are usually responsible for the "hollow" or "echoey" sound in your recordings.

The biggest problem in most rooms is bass frequencies. They especially love to build up in corners or anywhere flat surfaces meet. The only thing that kills bass frequencies is really dense material (well, not the only thing, but for our purposes, the only thing) such as bookshelves, couches, beds, really heavy blankets piled up in a corner and a closet full of clothes. Hanging a blanket behind your mic is not gonna stop those bass frequencies from bouncing back at your mic (though it may nip out a few of those irritating treble or high pitched frequencies). When you walk into a nice studio and it sounds so nice, quiet and clear, it's because they knew how to get rid of those bass frequencies. Don't stress yourself out about it, but do be aware of them.

Try not to set your mic right next to your computer or monitor. Well, try it, and if you don't hear your computer or monitor then good for you! (Note: In your headphones! Microphones and speakers do not make happy combinations near each other...) Your life just got easier. Otherwise, set it at least a few feet away, and make sure the end of the mic you speak into is facing away from any extraneous noise. All the mics I suggested reject most sound that comes from behind them (though a little bit may reflect back off the wall behind you...see how that works?)

You can drop money on the myriad types of foam, mini-booths and paneling to try to deal with echos, noises, reflections and problems, but without professional advice I wouldn't recommend you go too far. Much of the expense of building a professional studio is in the acoustics. It's just not worth the cost of getting carried away unless you'd rather be running a studio than performing your craft. Try things, use your ears and use your friends' ears. If you think it sounds close to what you hear in a real studio (or better yet on the air) then you've probably dealt with your acoustic problems as well as you can.
You may not find the TapeOp subscription as helpful, but it is free, and they do review a fair amount of hardware and software that might come in handy for you one day. Just don't get too bogged down in the equipment. Remember, if it sounds clear and clean, there's probably no reason to mess with it.

I do recommend logging in to Gearslutz now and again, though. They've added a forum on post production in the past year or so which is a great place to post or find help on voiceover, editing, and just general questions and information about the industry. Audiobooks and Narration people check out Librivox, which is a great site for practicing your skills and contributing to the community at large.

Don't forget a mic cable, a mic stand and some kind of music stand if you think think you need one for your copy.

And for those who are really on a budget and persevered this long, try the Snowball mic, made by Blue Microphone. It plugs right into your USB port (no need for an interface, preamp, etc...) and should work fine in Audacity, GarageBand or REAPER. (Don't forget to check the preferences in your software for something like "Audio Devices." That's where you tell it what interface/mic, etc... you want the software to see.) It's not gonna sound as nice as the other mics, but if you're just starting out, practicing, or possibly even for auditions from home, it should get you going. It runs about $100.

None of this is ideal, but the industry is certainly headed in this direction at the moment, and this is all a good start for doing work (or practice) from home.

Of course, if you suddenly find yourself producing full quality commercials, audiobooks or other VO for clients out of your home (which adds self-directing and self-engineering to the already difficult skill of acting) you may want to upgrade to some higher end equipment (including a proper soundbooth like these - you may also be able to build your own.) These recordings really should sound pristine. Yes, you're gonna pay for it, but if people are paying you for the gig, then it's probably worth the investment. Alternatively, you can take some of the burden off yourself (allowing you to produce higher quality work) by shopping around for a studio that will give you a good deal. If you become a solid, steady client, they may make it well worth your while. Besides which, their rooms, equipment, and staff are specialized for this kind of work the way your talents, skills and connections are specialized for acting.

Hopefully I haven't overcomplicated what is already a difficult endeavor for most people. When you're on a budget, and you're just trying to figure out how to make a living doing what you love, I think any and all of the above is a good start.

I'm starting to wish I had charged for this advice, but instead I'll just ask that if you find this useful, you contribute to our project by purchasing music and merchandise, coming to our shows (once we actually have shows), linking to our site(s), and spreading the word around about The Michelson-Morley Experiment (MME). Good luck, and HAVE FUN!

Frist Psot

Just to get the ball rolling, here's an official first post. As mentioned above, please let me know if you have any questions and I'll try to answer them both personally and on the blog for the benefit of anyone else. It's free, people. It's called helping each other out. If you really want to pay me for something, I'm sure we can work it out, but a lot of this stuff is pretty basic and I figure a lot of people just want a good nod as to whether they are going in the right direction or not. I think it's silly to charge money for something that basic (particularly since I'm sure many of the people that may visit here are going to be friends of mine and other people I have met personally.)

Have at it!
