proportions. You may also dynamically change the frequency multipliers, base frequency, modulation, and
modulation frequency for interesting effects. Click on the appropriate tab to change Initial and Final settings.
This button in the Final Settings dialog copies the tone values from the Initial Settings window

to the Final Settings window for editing.
This is where you enter the main frequency to be used for sound generation.
Base Frequency
This setting modulates the Base Frequency in pitch over a user-defined range. For example, a 100Hz setting
Modulate By
modulates the original frequency by +- 100Hz. In other words, a 1000Hz tone would modulate between 950Hz and
1050Hz.
This is the rate (times per second) at which the frequency modulates. Entering a value of 10, for
Modulation Frequency
instance, generates tones that seem to warble in amplitude at the rate of 10 times per second. The tones actually warble
in pitch (frequency) as they should, but because of the variance in the perceived energy levels of different frequencies to
the human ear, they seem to warble in amplitude.
Use the Frequency Components controls to add up to five overtones to the fundamental
Frequency Components
frequency (Base Frequency).
Enter the multiplier for each overtone below the Frequency Components slider(s). (The actual frequency will be this
many times the fundamental.) Then, use the sliders to mix each of the individual components (0 to 100%) in proportion
to one another. The overall gain (signal level) may be adjusted with the dB Volume sliders.
If the Lock to these settings only box isn't checked, all of the values can change over the duration of the audio file, so that
they morph from the initial to final settings.
You can generate several effects with these five overtones. Experiment and have fun.
Use the db Volume sliders to select the overall gain for each of the right and left channels from -80db to 0dB.
dB Volume
You can control both channels independently when generating stereo tones.
Choose the appropriate phase:
Phasing
Start Phase is the starting location in the cycle that will be produced. If you start at 0 degrees phase, waves will start at
•
the baseline. If you start at 90 degrees, the wave will start at full amplitude (generating a noticeable click as well). If
you are working in great detail with tones and need to have the phase "just so", this option allows you to control that.
Phase Difference purposefully allows the left channel to be out of phase with the right channel. A value of 0 will be
•
completely in-phase, and 180 will be completely out of phase.
Change Rate dynamically changes the relative phase between the two channels of a stereo audio file over time at a given
•
rate. For example, if you enter 1Hz, the phase difference will cycle through 360 degrees each second.
