The Glitzy, Ditzy Home Recording
Studio GLOSSARY - Learn & Laugh! 
This glossary is reprinted with permission from the Voice Actor's Guide to Recording At Home ... And On The Road - a soup-to-nuts guide to creating an inexpensive but professional-sounding recording studio in your home or on the road - with lots of laughs! Co-author and voice-over legend Harlan Hogan is also the inventive creator of the Voiceover Essentials online store.
By Harlan Hogan and Jeffrey P. Fisher
A glitzy, glowing, glimmering, glamorous – glossary! Our oh-so-handy guide to arcane audio terminology for posturing, posing, pontification pundits.
A to L
1. Listening and comparing two or more music, sound effects, or voice-over takes.
2. Letters not appearing on any of Harlan’s report cards.
1. The art and science of controlling sound in a space (acoustics).
2. Branch or twig of a tree where the species Zenaida macroura (mourning doves) perch and make that un-Godly cooing sound.
1. Audio Engineering Society – Meetings feature tuna sandwiches, fries and cash bar. Membership includes personalized pocket protector.
2. American Egotistical Society – Meetings feature All-You-Can-Stand buffet and open bar. Membership includes custom-fit earplugs for the networking meet-eat-greet portion of the program.
1. Room acoustics, reflections and reverberation. In essence, the audible sound of any room or environment, sometimes called room tone.
2. Fast moving, siren-bedecked emergency vehicle.
1. The process that increases signal strength of an audio source, i.e. boosting the low level signal from a mic to be loud enough to hear through a loudspeaker.
2. To re-explain/reiterate, as in: "What portion of NO don't you understand?”
1. Short for analogous. A fancy way of saying something is like something else. For example, electricity from a microphone is like (analogous/analog) the sound waves that strike it. Regular (non computer) audio sounds are called analog versus digital audio when you get your computer involved.
2. To build a roaring fire you’ll need kindling, a match, an-a-log.
Analog-to-Digital (A/D) Converter 
1. A device that converts analog audio signal into digital data (1s & 0s) and back again (digital-to-analog converter).
2. The major component in an audio interface or sound card.
3. Adderall, Ritalin and Dexedrine are often prescribed as Attention Deficit Converters.
1. To route or send an audio signal to one or more selected channels.
2. Graduation requirement Mr. Hogan consistently failed to complete, forcing him into a life as an itinerant actor trodding the boards, hat in hand.

1. The relative volume levels and placement of audio elements in a recording.
2. Lifestyle – wherein real people don’t talk like this.
Balanced Line
1. A cable with two conductors surrounded by a shield, in which each conductor is at equal impedance to ground. The cable's conductors are at opposite polarity, and the signal flows through both conductors. Balanced lines help reject noise

2. A much-underestimated way to feed the family with fresh-caught, freshwater fish.
1. Large vehicle used to spoil America’s youth - Jeffrey, for example. He never had to march through waist-high snow, ford turgid torrents of ankle-deep water, or run in Forest Gump terror from tornado-infested winds on the way to school like Harlan did. This explains a lot.
2. A common wire connecting a group of signals together – kind of the equivalent of USB, only with audio gear. Did you know USB stands for Universal Serial BUS? Yep!
Bus Master

2, The mic most VOs use.
CD-R and CD-RW
1. CD-Rs are recordable compact discs that can't be erased and reused, while CD-RWs are the opposite.
2. RD-D2’s second cousins.
Cellular Buzz (GSM Noise)

2. See also Angry Engineer.
3. See also Really Angry Engineer.
Complex Wave
1. A sound wave containing more than one frequency or harmonics.
2. Hairstyles, often involving extenders, curling irons and weaves.
1. A signal processor that reduces the dynamic range of an audio gain using an automatic volume control. The result is that louder sounds are lowered to the level of softer sounds. This allows the whole file to be raised in volume.

2. Abbreviation for Dead Beat. See also Actor, Itinerant.
1. An audio processing device that removes excessive sibilance (s and sh sounds) by detecting it and then reducing the sibilance volume automatically. A de-esser is, in essence, a frequency-controlled compressor.
2. Ice removal techniques used by most major airlines
1. The British term for mixing console/mixing board.
2. The British are weird.
Destructive Editing 
1. Editing that rewrites data on a hard drive permanently so edits cannot be undone.
2. Terrifying technique of our own, much-feared Prunella Sykes.

2. Fusion that makes a difference.
1. Any unwanted change in the audio waveform. It may be accompanied by a nasty, raspy, or gritty sound quality. The appearance of frequencies in a device's output signal that were not in the input signal. Distortion is caused by recording at too high a level, improper mixer settings, components failing, or vacuum tubes distorting. (Distortion can be desirable for some instances, such as a distorted electric guitar in the Heavy Metal music Harlan drifts off to most evenings about 9:30.)
2. Another popular political advertising genre.
3. Lies! I’m tellin’ ya’ It’s all lies!
1. Recorded tracks that have not yet had any signal processing applied to them.
2. Recorded tracks with no music or sound effects.

1. The range of recorded volume levels softest to loudest, i.e. the range of a whisper to a shout.
2. Although not as popular as the ubiquitous microwave, dynamic ranges are being embraced by many of the world’s top chefs.
1. The delayed and distinct repetition of a sound. If you shout "hello" into a canyon, you'll hear "hello, hello, hello, hello" repeating.
2. Little Sir’s last name.
Echo Chamber 
1. The British name for a physical echo chamber consisting of a hard-surfaced room with a widely separated loudspeaker and microphone to create and record reverberation. The Brits call reverb "echo" and the American’s call reverb, uh, "reverb," and then we call echo, "delay." Weird, eh? 
2. Electronic echo chambers can be hardware or software based.
3. The legendary movie sound effect, dubbed the Wilhelm Scream, was enhanced with echo chambers since first being heard in the 1951 B-movie Distant Drums. Since then, the scream has found it’s way into over 300 video games, commercials and movies from Star Wars and Raiders of the Lost Ark, to Batman Returns and Toy Story. Who says Hollywood isn’t green? They have been recycling this for a long, long time.
1. Originally, physically cutting and taping together magnetic tape to delete or rearrange audio.
2. Today, editing is done using computers without cutting any tape or your fingers.
1. Sound changing/enhancing effects like equalization, reverberation, echo/delay, flanging, chorusing, compression, de-essing, noise gate, etc.
2. See last.

Well done - now I'm ready to rock! I liked the one with R2D2 (nice CYA on the HOT one).

This was an educational and entertaining way to begin the morning, guys! Let me guess, was it Jeffrey that created the technical definitions, and Harlan, were you the one that went in a completely different and fun direction? Loved the an-a-log joke. See #2 Analog. Thanks a lot ... now it's stuck in my brain! Nice job on the glossary, gentlemen!
