**This will be an "open-computer" test (woohoo!).  Seems only fitting since you probably do not (yet) have Audition on your home machine.

Short Course in Digital Audio / Terms

At the most basic level, know how sound is produced.  This was even true back in the Neanderthal Era when Grog hit a hollow log with a stick.

From a short list of very tricky multiple-choice answers, be able to identify the basic principles of how a microphone works.

Be able to describe the difference between analog and digital technologies.

You may wanna bone up on the stats for the frequency range of human hearing.  (See Frequency Range in Terms.)  We'll leave Superman out of the mix for this one.

Even though MIDI files (.mid) are digital, know why they are much smaller than digital .wav files.  (Ah, that could explain why they don't sound quite as good.)

Everyone hates memorizing "stuff," but since we'll be working a lot with sampling rates, it would seem practical if you have a general grasp of Sampling Rates in relation to real life.  Sooo, I'll give you various sampling rate numbers in Hz and you'll match the rate to the entity to which it applies.  For example, 8,000 Hz = Telephone Quality; 44,100 Hz = CD quality.  Be familiar with everything from telephone quality through DVD quality sampling rates.  Shouldn't be too tough ... only a half dozen to match.  (See Sample Rate in Terms.)

Adobe Audition

Next time you have Audition open, take a look at the various file formats that are options when saving.  May even wanna know roughly how many types there are.

Re Device Ordering Preference & Multitrack Device Preference Order window, know why one must first make these selections before using Audition.  

Be able to explain to Granny what Surround Sound is.  (See Terms.)

Ah, the ol' Organizer Window in multitrack view ....  Know the easiest way to transfer "stuff" contained under any of the three tabs (Files, Effects, Favorites) to tracks.

Hmm ... I wonder just how many tracks there are in Audition??

Be able to describe a thing or two that right-clicking will do in Audition.

Be able to identify this handy button: 

Be familiar with various Track Properties features, such as Record, Solo, Mute, Pan.

Know what a Session File (.ses) is and is not.

When saving a session, know why one would not want to use a compressed file format.

Mixdown.  Know what it is and when to do it.

Be able to describe the general process for removing noise from an audio file.  Don't worry about all the cumbersome steps.  Just be able to hit the highlights.

Know what the Preview button can do for you in various windows.

In terms of splitting a track, know why CD Frame Boundaries should figure in.  (See Additional Tutorials re Audition item No. 8, Splitting Tracks.)

Be familiar with the color coding used on computer mini-jack ports.  (See Minijack Port Colors in terms.)

Be able to explain how one would physically import audio data from an external source (turntable, cassette deck) into a computer for manipulation via Audition.  Describe necessary cables, adapters, computer ports.  Most of all, have fun doing so.  ;-)

Copyright / Fair Use

There will be a few multiple choice questions dealing with basic info related to the amount of material that may be used for educational purposes in terms of:  (1) film, video, television, (2) text, (3) music, (4) image or photos.  While there are many links on the web related to this subject, for test purposes, I have used the chart located at the following web address:  Copyright and Fair Use Guidelines for Teachers (which is cited on this web).


Lastly, you should be familiar with a few more common terms that may be encountered in the world of digital audio.  Be able to provide short definitions/explanations/descriptions, whichever is most appropriate, for the following terms:

  • Crossfade

  • Time Code

  • Analog

  • Digital

  • Bit / Bit Resolution

  • Clipping

  • Level Meters / VU Meters
