Home Studio Essentials - Quick Tip 3 - Portable Vocal Booth

For many of us, our recording space is less than ideal. Perhaps you are setup in an extra bedroom, or even a closet (trust me, I’ve seen a few of these). Regardless of where you setup, the truth is you are likely to encounter room reflections in your recording. These problematic reverberations can really muddy up, and lessen the quality of our recordings. While a fully treated room is the best option for reducing room reflections, there are some work-arounds that might suit your needs. Yes, I’m talking about a portable mic booth.

It is possible to build a portable mic booth using materials that you can find at your local hardware store and insulation store. There are a plethora of Youtube videos and tutorials on the Internet to teach you how to safely and effectively build one of these, so I won’t go into much detail regarding how to build one. Rather, I want to encourage you to pursue solutions like this one for your recording problems.

The truth is, on a philosophical level, the very nature of audio engineering is problem solving. Since the dawn of recording, producers have come up with creative solutions to solve issues in their recordings or to inspire creativity. This day, I encourage you to explore your creativity to see what ideas you might have for improving your recordings!

Home Studio Essentials - Quick Tip 2 - The Pop Filter

In a recent blog, I mentioned the proximity effect and how we should be wary of it while recording. Having unwanted and uneccessary bass booming in a recording is easily avoidable, but you still might find an occasional unwanted sound in the low frequencies known as a plosive.

What’s a plosive, you ask? A plosive is the sudden burst of air that is exhaled when you use a “p” or a “b” in at the start of a syllable. That puff of breath hits the microphone, causing the all too familiar “pop” in the low frequencies and can be difficult to get rid of in a mix without cutting out all the bass frequencies. This is a where a pop filter comes to the rescue.

A pop filter is a mic stand attachment that places a mesh screen between the source and the microphone. The mesh captures and dissipates the plosive air burst and keeps it from hitting the microphone diaphragm, hence no “pop” of air in your recording. Now you can speak your p’s and b’s without fear, and we all know clear enunciation is important for voice overs!

Added Bonus

An added bonus to using a pop filter is that it regulates the distance you are from the microphone. A pop filter can be placed the proper distance from a microphone and then used to keep the vocalist in place while recording. This should make your mixing much easier later on!

Home Studio Essentials - Your Room

Whether you realise it or not, our ears are quite spectacular. Not only do we have two of them, allowing us to create a stereo image of the audio world around us, they are capable of recognizing differences in timing down to a tenth of a millisecond. They also are incredibly sensitive. Just Wikipedia “threshold of hearing” to find out. What does this tell us? It tells us that our ears hear more than just the source of a sound. It hears all the reflections that sound makes as well.

These reflections are generally known as “reverb.” Reverb is short for reverberance and, in short, is a part of almost every sound source you have ever heard. The only exception, would be if you have the fortune to experience an anechoic chamber (I hear they can be quite disturbing, actually!). Everywhere you are, the sound you hear bounces off of other surfaces, feeding our ears information that identifies the shape of the room, the texture of the room, and many other things.

Interestingly, though, our ears take most of this information passively. It hardly ever registers in your mind that a room is particularly lively or dead. That is until you record in it.

You may have noticed by now, that if you’re recording in a room without much furniture, hard wood floors, or very little hanging on the walls, your recordings likely have a lot of natural reverb and reflection in them. This is both a good and a bad thing.

This is a good thing if you’re recording something in a fantastic sounding room. Recording studios dedicate spaces to this very thing, enabling engineers to record the room ambience as well as the source signal. But for voice overs, room noise might not be your best friend.

Most of you understand that you are trying to get the tightest, cleanest sound possible into your recordings. Having good mic technique will get you part of the way there. The other part is done by treating your room.

Just as you’ve seen in countless pictures of professional studios, sound absorbing foam is your friend in your home studio. Not only will you reduce the reverb of your sound source (that is your voice), you will also reduce the natural reverb of the room. Often, without even realizing it, our recording space has low level background noise. In an untreated room, all this low volume noise bounces around the room just the same as higher level noises. It creates a cacophony of background noise that you can’t easily scrub from your recordings. Room treatment will deaden those reflective surfaces and thus deaden the natural reverberation of those low level noises, i.e. your room will be quieter giving you greater headroom between your sound source and when no sound is being recorded.

Places to Consider Treating

For voice overs, particularly you want to try and create a quiet space that you can record your voice into. Too small of a room and you might find a lot of bass build up as those long bass waves bounce around the tight space. Too big of a room, and your voice will sound thinner and drier. I realize that most of you cannot change the size of the room you are recording in. I simply state these facts so that you can make adjustments depending upon your recording space.

To figure out where to put absorbing foam, think of how sound travels. Try and figure out the natural reflections of the walls and place foam accordingly. If you know that you will generally speak into your microphone in a general direction of your room, you can place foam where the source will naturally reflect to reduce reflections bouncing back into the microphone.

It is also a good idea to put absorbing foam behind your monitors and possibly on your ceiling as well. The ceiling in most rooms tends to be flat and hard, making it considerably reflective. Placing some foam above the area you record or mix (or both) will make a big difference as to how much room reflection is heard.

Bottom Line

A good engineer needs to be in control of her room acoustics. This means treating the space that you record and mix in. Since our ears are so sensitive, it behooves us to absorb the reflections in our room to create cleaner, better sounding mixes. Before running off to buy a more expensive microphone or another piece of gear, consider treating your room. Remember, a treated room will improve all of your recordings!

Home Studio Essentials - Quick Tip 1 - Room Noise Trick

Here’s a quick tip for you to try today. Ever made a bunch of cuts to a vocal take cleaning it up and then thought it sounded odd as the track was silent in the missing audio? Let me help you with that.

The truth is, most recording environments, especially home studios, have some level of noise other than the sound source. This could be a natural reverb or some background noise in your recording environment. When you cut up your takes, the silence sounds odd because your ears were hearing this “noise” even if it was not very prevalent in the mix.

One trick to help your tracks sound consistent is to record a few seconds worth of “silence” in the recording environment on the day you record. Then chop it up and fill in the gaps of your track with the background noise. This way, when the original track drops out, it doesn’t sound like someone turned the mic off!

Another way to do this would be to use a side-chain compression technique known as ducking. Essentially, you would have a loop or track of the “silence” playing on one track and your take on another. Then, you would put a compressor on your silence track but have it respond to the vocal take track. Set the ratio high and the threshold low and watch as every time the audio track goes to silent, the compressor backs off the “silence” track allowing the room noise to come through.

If “ducking” is a bit confusing, we will be discussing side-chain compression in the near future. No need to fret!

Hope this quick tip helps and come back for more soon!
