You can use the Scrub tool to locate or audition a particular sound or
passage as you drag the mouse. You can scrub a single audio track by
dragging over that track or all tracks by dragging in the Time Ruler.
Note: The Scrub tool is not affected by current Mute and Solo settings of a
track.
To Audition Audio with the Scrub Tool
1. Click the Scrub tool .
2. Click and drag the pointer over an audio track.
Tip: To hear the clips in all audio tracks, drag with the Scrub tool in the
horizontal ruler.
Basic Audio Processing
Audio processing commands let you modify audio data according to some
rule or algorithm. The rule can be as simple as reversing the audio data or
boosting it by a certain factor, or as complex as performing a Fourier
analysis and selectively amplifying or attenuating sounds at certain
frequencies.
Audio processing commands can work on whole, partial and non-
contiguous clips. For example, suppose you want to make certain words in
a vocal passage softer. You can create a volume envelope and use it to
lower the volume, non-destructively in just the section of the track
containing those words. You could also use the Process-Audio-Gain
command to lower the volume destructively.
You should listen to the results of your work after each audio processing
command. If you don’t like what you hear, you can use Edit-Undo to
restore your audio data to its previous state.
Many of the dialog boxes associated with SONAR’s audio processing and
effects commands have two important features: Audition and Presets.
The Audition button is used to audition the processed audio data. When you
click Audition, SONAR processes the first few seconds of your data, then
plays it repeatedly until you click Stop. This helps you to get an idea of
whether the settings in the dialog box are producing the desired effect.
The audition duration is three seconds by default. You can change this
value by choosing Options-Global, selecting the General tab and
changing Audition Commands for ( ) Seconds.
