The science of acoustics is something that tends to alternately baffle and intimidate most of us. Outside of a handful of highly trained individuals, the aspects of what makes a room sound a certain way is looked upon as a sort of black art. Performance venues and upscale recording studios routinely include acoustic designers in their construction budgets, spending considerable sums of money in pursuit of sonic perfection.

No one will argue that digital technology has done much to empower musicians to take control over their recordings. Today’s artists are far less dependent on high-priced recording professionals, with many great-sounding projects having never even seen the inside of a recording studio.

Ask ten recording engineers about recording drums and you’re likely to get more than 20 opinions. Few instruments combine subtle nuance and brute force the way a good drummer can, and capturing that sound has been the subject of hundreds of articles and thousands of conversations.

For those of us who toiled over faders back when the earth was still cooling, the concept of gain structure was fairly easy to grasp. Each separate box was a link in the audio chain, visibly connected via patch cables, and analog distortion was easy to hear and identify. In today’s all-digital, all-in-the-box world, it’s not that simple. Signal paths can be unconventional and convoluted, and digital distortion can be subtle and sneaky.

In the never-ending quest for the perfect mix, EQ is one of the oldest tools we have, and still one of the most powerful. Used in moderation, EQ can add clarity and definition to a crowded soundscape. Used with precision, it can remove offending sounds we wish we hadn’t captured. As a strategic tool, a bit of EQ can make all the difference needed to separate dueling guitars, scoop the mud from your drums or make a vocal shine.

There were many recording techniques used in my years as an engineer back in Detroit in the various recording studios around: Selah, Sound Suite, Vanguard, LaMonte’s, United Sound, Studio A, and more. I shared some of these memories with another fellow Detroiter, the great engineer Reggie Dozier (brother of Lamont Dozier from Holland-Dozier-Holland), over lunch to help me recall the analog days.

The mastering engineer is the last step of the artistic phase, and the first step of the manufacturing phase. It’s the final opportunity to listen, polish, and make a change in the sonic presentation. It is also the first step of the manufacturing phase, because it prepares the master in the way that best suits the needs of the manufacturer.

The goal is to listen to the broad picture; the actual content is immaterial. The mastering engineer is paying attention to EQ presentation, to level presentation, to dynamics presentation.

Compressors and limiters are specialized amplifiers used to reduce dynamic range — the span between the softest and loudest sounds. The use of compressors can make recordings and live mixes sound more polished by controlling maximum levels and maintaining higher average loudness. Additionally, many compressors — both hardware and software — will have a signature sound that can be used to inject wonderful coloration and tone into otherwise lifeless tracks.

Of all the components that make up your studio environment, the two most important for producing high-quality mixes have to be, 1) your ears and 2) your near-field monitors. More specifically, the proper placement of these key components within your room will make all the difference in achieving accurate mixes that will sound good on the widest range of systems.
