This is a great opportunity to practice, especially if you've never edited sound before. Take a few minutes and access one of the free tools listed above, record some audio, then play with the editing tools described in this section. You might be surprised at what you create - or horribly disappointed! Either way, practice is a great way to learn these concepts.
part three: sound editing tutorials
Note: Audio CD’s can be edited digitally (as shown in the video above) by ripping (saving) the CD to a PC
Part four: Microphones
Microphones are very diversified and all can be used for capturing sound that can then be edited using the techniques already presented. Here are some common microphones. Click on the microphone title for more info.
- Condenser Microphone - has a built in amplifier. Used for indoor, studio locations.
- Shotgun/Boom microphone - used for both single voices and to record groups
- Pressure zone microphone - used to lie flat such as on the floor, a table, or a podium
- Handheld microphone - used typically for one person at a time
- Wireless/Lavalier microphone - used for hands free amplification
part five: audio terminology
Amplify – To increase the volume of sound, usually with an amplifier, which alters the ratio of input signal and output signal, usually measured in decibels, with its gain control.
Attenuate –In terms of audio editing, it means to reduce the level of a signal or sound; basically, it is the opposite of amplification. This is often accomplished with EQ filters.
Band Pass Filter – This is a common tool in audio editing software that allows you to designate which frequencies will be impacted and which will pass through a specific filter unchanged. This allows you to cut the low-end frequencies for a vocal track, for example, to eliminate noise in low frequencies that the human voice does not produce.
Change Pitch - Changing the frequency (pitch) of a sound. This makes the audio sound high or low.
Compressor – A compressor is essentially a dynamic volume control. It is an audio editing tool used to reduce the range of an audio signal, making loud sounds quieter and quiet sounds louder to even out the overall volume. This is one of the most basic and frequently used tools in audio production, along with equalizers.
Decibel (dB) – A logarithmic ratio used to indicate sound intensity by measuring the output power of an electrical signal as it relates to volume, voltage and current.
Delay - when sound pauses or stops for a moment.
Distortion - creating a "warm", "dirty", or "fuzzy" sound by compressing the peaks of the sound wave.
Equalizer – This is a control panel that allows you to raise and lower the volume of specific frequencies within a piece of music and its individual components. This is one of the most basic and commonly used tools in audio production.
Flange – This is a type of sound effect that mixes two identical signals together, with one signal constant and the other slightly delayed by continually changing periods, usually between 1 and 20 milliseconds. Flanging gives an audio signal a swirling-like sound effect.
Line-in – A term used to indicate the ability to record from line-level audio equipment such as microphones and electronic instruments' outputs.
Microphone - An instrument that converts sound waves into an electric current. This microphone is plugged into an amplifier.
MIDI – Short for musical instrument digital interface, this term refers to an industry specification that allows digital instruments and computers to interface with each other. It also links multiple instruments so that a single sequence of tones played live or recorded can be simultaneously reproduced by a large number of synthesizers and instrument voices for a "wall of sound" type effect. MIDI is used in nearly all audio production, to varying extents. MIDI files allow for editing of musical instruments individually
Noise Reduction – Audio editors generally have tools to remove hiss, hums or other unwanted sounds. It is a type of EQ filter.
Normalize – This is a process by which the gain of audio is increased to its maximum volume. With audio editing software, this can be applied to real-time playback but is generally used when mixing a multi-track project to a stereo output signal to create a single audio file.
Pop/Click – These are the loud, abrupt sounds that are common in older recordings. Audio editing software generally has tools to eliminate these sounds from your music.
Reverb – Short for reverberation, reverb controls the amount of echo applied to the original sound to simulate the way that the input signal or instrument would sound if it were played acoustically in a variety of environments, from small rooms to concert halls. Reverb is one of the most commonly used effects in audio production.
Smoother – This audio editor tool can smooth out music by eliminating hisses and crackle noises in older recordings.
Silence Reduction – This tool can remove unwanted silent spots from your music, often automatically.
Vibrato – This is a quick, pulsating change in pitch. This effect can be added to any sound signal.

Crop - Using the crop function allows you to drag a rectangular shape around an area in your image to cut off the sides to make it the proper size or to remove unwanted parts. Most graphics applications allow you to crop images with a clip feature.
Paint Tool - The Painting tool changes the area of your image where you use the cursor to add paint strokes to the image. You can use this tool to fill in single pixels, add hard or soft lines, or select areas to fill in with a solid color or, some programs will allow you to paint with a texture rather than a single color.
Brush - A part of the Paint tool that that allows you to select a brush shape (square, circle, oval and so on) and also the the thickness in pixels you want to paint on your image with. As you move your cursor over the image it leaves a stroke of color.
Dropper - The Dropper tool allows you to choose a foreground or background color from your image to work with. If you had a specific blue in your image that you wanted to use with the paint tool, for example, you would use the dropper and click on one of the blue pixels to change your foreground color.
Eraser - Eraser tools allow you to erase areas within your image to leave behind transparency or a background color. There is also a Background Eraser which provides more control in removing a background to transparent.

competency 002 E
Knows how to define the design attributes and requirements of products created for a variety of purposes (e.g., posters, stationery, brochures, slideshows, Web pages, multimedia presentations).
The design attributes (principles) and terminology are described in Part D above. Applying these principles to a variety of products requires some adapting but the basics do not change. The layout of this section of the study guide is as follows:
Part 1 Appearance
Part 2 Content
Part 3 Brain Rules for presenters
part one: appearance
Graphics, color, simplicity, and easily read text all come together. Here's an example from one of my photographer friends.
See more at Justin's website: http://www.justinclemons.com
Part two: content
The content of any product must be well written and have substance. Here's a prime example of an eye catching brochure design with little to no valuable content. There's just too much open space and not enough meaningful information. Image Source |
In contrast, here is an example of a brochure with exceptional design and meaningful content. Make sure the content is well written, error free, and rich with valuable information. Image Source |
part three: brain rules
Check out this article from Spritz. This is an EXCELLENT resource that includes great descriptions of the principles of design and their appropriate use in designing FANTASTIC products: http://www.spritzweb.com/resources/good-website-characteristics.html
