Loudness distribution tool
This analysis tool measures the most frequent loudness found in an audio 
file (this is different from average loudness). The graphic peaks found by 
the analysis represent these values.
The following parameters can be set:
Parameter Description
Resolution Loudness is the average audio volume computed over a given period. 
This parameter represents this period. Smaller time values are more 
suited for sections with abrupt changes in level, like drum...

Audio Signal Generator
This utility allows you to synthesize audio documents from scratch. The 
resulting documents can then be used for a number of purposes:
• For testing the specifications of audio equipment.
• For measurements of various kinds, including calibrating tape recorders.
• For testing signal processing methods.
• For educational purposes.
The Audio Signal Generator is not intended for synthesizing musical 
sounds.
The Signal Generator is based on a...

Proceed as follows:
1.Select the Audio Signal Generator option on the Tools menu.
2.
Decide on a number of layers, by setting the “Number of layers” para-
meter at the bottom of the dialog.
You can always change this value at a later stage if required.
3.Select one of the layers, using the “Edit layer” parameter.
4.Decide if you want to make changes for both or just one of the channels in 
this layer, by using the “Edit channel(s)” pop-up.
5.Make the required settings...

DTMF Generator
DTMF (Dual Tone Multi Frequency – or Touch Tone) is a way of generat-
ing signals by combining two sine waves with variable frequencies, used 
in telephone systems. The numbers you press generate sine waves of dif-
ferent frequencies, and these signals are then decoded at the central 
telephone office to actually identify which numbers you press.
The DTMF Generator does just this – it allows you to generate an audio 
file with the sounds you hear when...

5.Select a bit resolution and a sample rate for the file to be created.
When you click the button, the Audio Properties dialog (see “Editing audio properties” on 
page 127) opens to let you make settings for the audio file.
6.If you wish, you can save the settings you make as a preset.
You can create presets for settings in the dialog, for quick recall.
7.When the settings are to your satisfaction, click Generate.
The file is generated and opens up in a new window.

27 – 650 Synchronizing WaveLab to external devices
Introduction
It is possible to synchronize the audio playback in WaveLab to incoming 
MIDI Time Code (MTC), or via the ASIO Positioning Protocol (for sample 
accurate sync). 
• For MTC sync to be possible, you need to have a MIDI Interface installed 
and working!
• For sync to ASIO Positioning Protocol, you need compatible audio hardware 
with a built-in time code reader.
See “Sync to ASIO Positioning Protocol (APP)” on page 656.
