Focusing Hot Points
After a global analysis, you can focus the display on a certain hot point.
PREREQUISITE 
In the Audio Files workspace, select Analysis > Global Analysis, and 
perform the analysis.
PROCEDURE
1. Use the Number of hot points scroll bar to move the position 
indicator to the position in which you are.
2. Click the Focus button.
The wave window zooms in on the selected point. The Global Analysis 
dialog is reduced to the bottom part.
3. To return...

3D Frequency Analysis
142
The wheel control allows you to view the frequency spectrum from 
different angles. For example, you can open several 3D Frequency 
Analysis windows, each with a different perspective. This allows you to 
get a better view of an otherwise crowded graph.
Creating a Graph for 3D Frequency Analysis
The length of the selected audio affects the accuracy of the analysis. For 
short selections, the result is more detailed. Consider making a separate 
analysis of the...

3D Analysis Options
In the options dialog of the 3D Frequency Analysis dialog, you can 
define which frequency range is analyzed and modify the appearance of 
the graph for the 3D frequency analysis.
In the Audio Files workspace, select Analysis > 3D Frequency 
Analysis, and click the 3D analysis options button.

Offline Processing
Offline processes are useful for a variety of editing purposes and 
creative effects. For example, when the computer is too slow for 
real-time processing or when the editing requires more than one pass.
After the processing the audio file is permanently altered.
Applying Processing
Processing can be applied to a selection or to a whole file. For certain 
operations processing the entire file is necessary.
NOTE
If Process whole file if there is no selection is activated in the...

Gain Dialog
145
Gain Dialog
In this dialog, you can apply a gain to change the level of an audio file.
In the Audio Files workspace, select Process > Gain.
Click Find current peak level to obtain a report on the peak level of the 
audio selection, or the whole file if there is no selection. This is useful if 
you want to calculate how much you can increase the overall gain of a 
file without clipping (exceeding 0
 dB), for example.
This processor also lets you add clipping. Clipping is...

Normalize Level Dialog
146
Mix to Mono
Mixes the left and the right channel. The resulting mono file will 
have the specified peak level. This ensures a mix without clipping.
Find current peak value
Creates a report on the peak level of the current audio selection, 
or the whole audio file if there is no selection.
Basic Envelope Operations
By adding points to the envelope curve you can create an envelope 
curve that changes the volume of the material over time. When you point 
the...

Fades in Audio Files
147
Fades in Audio Files
A fade-in is a gradual increase in level and a fade-out is a gradual 
decrease in level.
You can create fades by selecting an individual fading type for each 
fade-in/fade-out, or by using the Easy Fade function.
Creating a Fade-In and Fade-Out
PROCEDURE
1.In the Audio Files workspace, make a selection.
2. Depending whether you want to create a fade-in or a fade-out, 
select one of the following:
• To create a fade-in, select Process >...

Crossfades
148
Crossfades
A crossfade is a gradual fade between two sounds, where one is faded 
in and the other faded out. You can automatically create a crossfade 
when pasting an audio section into another.
Creating Crossfades
The material that you want to crossfade can either be in two different 
sections of the same audio file, or in two different audio files.
PROCEDURE
1.In the Audio Files workspace, select the section that you want to 
fade-in.
2. Select Edit > Copy, or press...

Paste and Crossfade Options
These options allow you to select a crossfade type for pasting.
In the Audio Files workspace, select Edit > Paste and crossfade.
Linear (equal gain)
Level changes linearly.
Sinus (equal power)
Level changes according to a sine curve, the power of the mix 
remains constant.
Square-root (equal power)
Level changes according to the square-root curve, the power of 
the mix remains constant.

Reversing Audio
You can reverse an audio file or a part of an audio file as if playing a tape 
backwards.
PROCEDURE
1.Optional: If you only want to reverse a certain time range of the 
audio file, create a selection range in the wave window.
2. In the Audio Files workspace, select Process > Reverse.
DC Offset
A DC offset is when there is too large a DC (direct current) component 
in the signal. This most often appears due to mismatches between 
various types of...
