5.7.3 Signal generator
This dialog allows you to generate complex synthesized sounds in mono or stereo.
You can layer different waveform generators together and if outputting a stereo file, adjust
different settings for both the left and right channels. There are a multitude of settings to
adjust the character (Source tab), frequency (Frequency tab) and amplitude (Level tab) of
the generated signals.
To generate a sound follow these basic steps:
choose whether the file is to be mono or stereo, and define the number of samples, and
bit depth using the Audio properties dialog.
choose how many layers of signal generators you wish to use (up to 64).
for each layer, use the source tab to choose the type of signal generator you wish to
use, switch to the frequency tab to define a frequency and its envelope, and use the
level tab to define a level envelope. If you have chosen a stereo file you can also choose
to adjust left and right channels independently.
once all settings are made, choose Generate and WaveLab calculates an Audio File
according to your specifications. The file is generated and opens up in a new window.
Generating signals can be useful for a variety of testing and measurement purposes. For
example, you could use the Signal Generator to create a sine wave sweep from say 20Hz to
20,000kHz to test your monitoring environment for resonant frequencies.
You can access this dialog in the Audio File Workspace via Tools > Signal Generator....

5.7.4 DTMF Generator
This dialog allows you to generate DTMF (Dual-tone multi-frequency) or MF tones as used
by some analog telephone systems.
These signals are created by combining two sine waves with variable frequencies together.
Push button telephones generate these two sine waves at different frequencies depending
on the number you press. These dial pulses are then decoded by the telephone exchange
to identify which letters or numbers you pressed.
