Audio effects• Effects, also called signal processors, can “sweeten” audio as well as fix problems(such as too much treble or bass). 

• They are the audio equivalent of video effects,like contrast, sharpen, color balance, light rays, pixelate, and so on.. 

• In fact, sometimes audio engineerseven use similar terms, like “brightness,”to describe increased treble.

Destructive vs. Non‐destructive effects

Inserting an effect doesn’t change the file but instead plays the original file back through the effect. This is called a nondestructive process using a real-time effect because the original file remains unaltered.

However, you may want to apply the effect to the entire file, or only a selection, so that saving the file saves the processed version.

Signal ProcessingTwo main elements of working with digital audio involve:1. Editing the waveform (cutting, pasting, mixing)2. Using signal processing to alter some element of the 

waveform (amplitude, pitch, EQ, etc.)

Signal processors allow you to make substantial modifications to digital audio files

Page 7: 06 Using Audition Built in Effects

Process for applying effects to a digital audio file1. Apply effects to audio so that the result becomes a 

permanent, “embedded” part of the audio file2. Apply single  or multiple effects (effects rack)3. Adjust parameters in various effects to process audio in 

specific ways.4. Alter dynamics, frequency response, ambience and other 

audio attributes.5. Create favorite presets that can be applied immediately to 

audio by selecting them.

The Effects Menu

When you need to apply only one specific effect, using this menu is quicker than using the Effects Rack.

Page 9: 06 Using Audition Built in Effects

The Effects Rack• The Effects Rack allows you to create a chain of up to 16 effects, which you can enable or disable independently. 

• You can add, delete, replace, or reorder effects.• The Effects Rack is the most flexible way of working with effects.

The Effects Rack can be used BOTH in the Waveform and Multitrack editors

• If you come up with a particularly useful effects setting, you can saveit as a Favorite preset.

Amplitude and Compression ‐ change levels or alter dynamics

Amplitude – level of sound (loudness or softness).• Compression changes the relationship of the output signal to the input signal.

Threshold ‐ the level above which compression starts to occurRatio  ‐ sets amount of change in the output signal for a given input signal change.

Compression is increasing output levels while avoiding overload or distortion taking the form of a Hard Limiter.

• Compression can make a sound subjectively louder and is the tool that makes TVcommercials SO MUCH LOUDER THAN EVERYTHING ELSE.

Page 14: 06 Using Audition Built in Effects

Amplitude and Compression ‐ change levels or alter dynamics

The Speech Volume Leveler evens‐out level variations with narration, as well as reduce background noise with some signals.

Normalization is the application of a constant amount of gain to bring the average or peak amplitude to a target level (the norm).Normalization usually is safe at 0db

Page 15: 06 Using Audition Built in Effects

Echo – Reverb ‐ DelayEcho is a repeating sound as it fades away.

Delaymeans the sound comes late after it has been produced and being heard for a specified period of time.

Reverb is a lot like a shorter echo in that it creates the acoustics of a note bouncing off the walls of an enclosed space (which is why we all song so good singing in an enclosed shower).

Page 16: 06 Using Audition Built in Effects

Filter and EQ • Equalization is an extremely important effect for adjusting tonality. 

• For example, you can “brighten” muffled narration by boosting the treble or make tinny, thin sounding voices sound fuller by increasing the low frequencies.

A Graphic Equalizer can boost or cut with a fixed bandwidth at various fixed frequencies.• It gets its name because moving the sliders creates a “graph” of the filter’s frequency response.

Page 17: 06 Using Audition Built in Effects

Filter and EQ A Parametric Equalizer is a more complex type of EQ which controls more parameters of the sound than a graphic equalizer. A parametric equalizer can control three aspects of each frequency: level (boost or cut), the center or primary frequency and the bandwidth or range of each frequency.

Overall, if you need an audio equalizer, a parametric equalizer allows much more detailed control of the sound and permits finer adjustments.

Time and Pitch• Automatic Pitch Correction is the sole effect under the Time and Pitch effect is designed for vocals and corrects the pitch of notes so that they are in tune.

• However, be careful when applying this effect; many vocalists deliberately sing some notes a little flat or sharp to add interest or tension to a vocal; correcting these can remove a vocal’s “human” quality.

• In animation and game design, you can use this effect to define unique voice qualities of the characters or sound effects.

Stereo Imagery – alter a file’s stereo image

• Center Channel Extractor ‐With stereo signals, some sounds are traditionally mixed to center—particularly vocals, bass, and kick drum. 

• Reversing the phase of one channel cancels out any material panned to center while leaving signals panned left and right alone. 

• This is commonly used for karaoke to remove (or minimize) usually the main vocal parts of a song.

Page 21: 06 Using Audition Built in Effects

Special – Guitar SuiteThe Guitar Suite is a “channel strip” that emulates a guitar signal processing chain.

• However, Guitar Suite is also useful for other musical instruments particularly to drums.
