Creating a Soundtrack in

Adobe Audition CS6Slide2

Exploring Audition

Adobe Audition, like Premiere Pro and After Effects, includes a number of preformatted, customizable workspaces that optimize the arrangement of panels for particular tasks.

When you select one of the preformatted workspaces, the current workspace is adjusted accordingly.Slide3

Exploring Audition

The Default workspace is designed to optimize audio editing by providing a large view of the Editor panel.

The workspace can be changed by selecting a default workspace or by rearranging the panels to your individual preference.Slide4

Exploring Audition

Audition is designed for the non-musical professional to edit and create musical scores.

However, an understanding of some fundamental digital audio concepts will help you as you work with Audition.Slide6

Exploring Audition

Sound is created by a vibration in the air created by an object that causes the air pressure to change.

This vibration eventually reaches the eardrum causing it to vibrate, which is then interpreted as sound.Slide7

Exploring Audition

Sound is represented in a waveform, which is a line that visually depicts the variations in the waves being created by the air pressure, much like the way wind creates waves in water.Slide8

A sample waveform on the Editor panel

Exploring AuditionSlide9

Exploring Audition

The line at its high point, caused by higher pressure, is called its

crest

.Lower pressure is represented at the line’s lowest point and is called its trough

.

When there is no air pressure, the sound wave is at zero, which is indicated by the red zero line.Slide10

Exploring Audition

Amplitude is the change in pressure from crest to trough.

High-amplitude waveforms are loud and lowamplitude waveforms are quiet.Slide11

The number of cycles per second, measured in hertz, is called

frequency

.A wavelength is the distance in inches or centimeters measured between any two points, at the same height on the waveform.Slide13

Exploring Audition

The Files panel organizes the references to all of the files used in a session and also lists the multitrack sessions.Slide14

Exploring Audition

You can use Audition to import audio files or to record audio.

A variety of audio and video file formats are supported, including:

Exploring Audition

Audition has two different editors that can be used when working with audio files:

The Waveform Editor

The Multitrack EditorSlide17

Exploring Audition

The Waveform Editor:

is used to edit individual files.

uses a destructive method of editing.Destructive editing means that any changes that are made are permanent and cannot be undone.

A destructive edit is not applied until you save the file.Slide18

Waveform Editor

Exploring AuditionSlide19

Exploring Audition

The Multitrack Editor:

is used to mix multiple audio files and can be used to integrate them with video.

Uses a nondestructive method.Nondestructive editing means that the audio file is not changed permanently and can be undone.

Nondestructive editing requires more processing power but provides greater flexibility.Slide20

Multitrack Editor

Exploring AuditionSlide21

Working with Multitrack

Sessions

Audition allows you to combine audio files and mix settings to create soundtracks for videos that you can then import into Premiere Pro or After Effects.

A multitrack session is a file that contains references to source files and mix settings of multiple tracks, keeping the file relatively small.

The extension for an Audition document is .sesx.Slide22

Working with Multitrack

Sessions

Multitrack sessions support importing video files to use as references while mixing a soundtrack, allowing you to synchronize your music.

A multitrack session can be created before or after you import your movie file.Slide23

Multitracks appear on the Multitrack Editor panel, and you can quickly switch between audio files by selecting the drop-down menu on the Editor panel.Slide24

Tracks can be renamed by clicking the current name and typing a new name.

If you have several audio tracks, it is helpful to assign them descriptive names so that you can easily keep track of where each sound effect or audio clip is located.Slide26

Working with Multitrack

Sessions

Audio files on the Files panel can be placed on an audio track by dragging them to the

Multitrack Editor panel.

An audio file that has been placed on a track is known as a

clip

.

Adjusting the length or duration of an audio clip is as simple as clicking and dragging.Slide27

The placement of a clip on a track can also be adjusted by clicking and dragging the clip with the Move tool.

It is a good idea to place clips on separate tracks so that you can overlap them to eliminate the cut from one audio clip to the next.Slide29

You can also add keyframes for the volume level allowing you to create and fade from one audio clip to the next.Slide30

You can create a fade in or a fade out effect between audio clips by right-clicking the fade icon.

You can then adjust the length of the fade by dragging the fade icon.

You can adjust the amount of fade by dragging up or down to create a curve.Slide32

When working in the Multitrack Editor, each clip and track has its own Effects Rack panel.

Effects are nondestructive in the Multitrack Editor and can be changed at any time.The Effects Rack panel allows you to apply up to 16 different effects to each track or clip.Slide34

While you are performing edits on a soundtrack and syncing it to video, you should keep it in the Audition SESX file format.

The SESX format allows you to add effects and to adjust fades.Slide36

Working with Multitrack

Sessions

You can also import a file in the SESX format directly into Premiere Pro and After Effects and access the file from those applications for editing.

The Save As dialog box allows you to rename a multitrack session and change the location where it is saved.Slide37

When you are done editing your file and ready to save it for playback or for use on other devices, you need to do what is called a

mix down

, which is a process that combines all of your audio tracks and outputs them together.

This is accomplished using the Export

Multitrack

Mixdown

command.Slide39

As part of this process, you need to choose an

audio file format to save in.The MP3 file format is one of the most widely used file formats for portable media players and web-based audio.

has a highly compressed file size to make downloads faster, but also results in poorer quality.Slide41

Use the MP3 file format when saving for the Web or for portable media players.

Windows Waveform, or WAV, is the standard, uncompressed audio format for the Windows operating system.Slide43

Working with Multitrack

Sessions

Audio Interchange File Format, or AIF, is the standard, uncompressed audio file format for Mac OS.

You should use these file formats when you plan to share your files with other applications or burn them to discs.Slide44

Cleaning Up Audio Files

Audition can be used to clean up and restore audio files.

For example, crackling noises from old vinyl records or microphone recordings can be removed with the Automatic Click Remover effect.Slide45

Cleaning Up Audio Files

Background noise such as wind or humming can be removed with the Adaptive Noise effect.

These effects can be used in either the Waveform Editor or the Multitrack Editor.Slide46

Cleaning Up Audio Files

If you want to correct multiple problems or identify the noise you want removed, the Noise Reduction effect can be used.

Using the Noise Reduction effect can significantly reduce any unwanted noise that is constant throughout the waveform.Slide47

Cleaning Up Audio Files

The Noise Reduction effect is only available in the Waveform Editor and is therefore a destructive edit.Slide48

Cleaning Up Audio Files

By default, the Waveform Editor displays an audio file as a waveform showing amplitude changes.

The Waveform Editor can also display an audio file as a Spectral Frequency display, or spectral display.

In this display, the x-axis measures time and the y-axis measures frequency.Slide49

You can use the spectral display to identify and select noise.

Bright vertical bars that extend from the top to the bottom are usually clicks and crackles.

Light red clouds that extend across the top of the display are usually hissing noises.Slide51

Before you can apply the Noise Reduction command, you need to identify the noise.

A noise can be selected with the Rectangular Marquee tool in the spectral display to generate a sample of the noise you wish to remove.

The Capture Noise Print command creates a noise print, which is a sample of the artifact you want to remove from the audio file.Slide55

The Noise Reduction setting in the Effect –Noise Reduction dialog box sets the amplitude of the noise floor.

The noise floor is the level of amplitude representing the near-constant background noise that you have identified and are trying to remove.Slide57
