Sound Card Tone Frequency Dialog
The Tone Freq button and associated frequency control appear when the Wave type is repetitive. Clicking the button opens the Tone Frequency dialog.
When the Wave type is Play, the button changes to Play Rate and the control becomes a multiplier (labeled 'X' instead of 'Hz') of the original rate. (But see the Play Rate Absolute / Relative control in the Play dialog.) Clicking the Play Rate button still opens Tone Frequency dialog.
When the Wave is one of the Noise types, the button changes to Timing and opens a special Timing dialog if clicked. The control below the button is typically the Smooth TC value from the Timing dialog.
If all you wish to do is change the frequency of a wave (or playback rate of a Play file), you may use the Tone Freq (or Play Rate) control directly. If you click on the button, the Tone Frequency dialog allows control of not only the frequency or rate, but also the phase and Gen Sync resolution. In addition, there are controls to select when the phase should be reset, such as at the start of each Burst or Sweep. You may also change the frequency entry mode to make it easier to enter frequencies that fall on certain values.
For convenience, the Phase, Frequency, and Frequency Entry Mode controls are also duplicated in the AM, FM, and Phase, Modulation dialogs. The Sweep dialog includes duplicates for Frequency (as the Start frequency) and Frequency Entry Mode, but not Phase.
Tone Frequency Dialog:
Note that you do not need to open this dialog to change any of its controls directly via macro command. You can even change those controls when the Wave is non-repetitive and this dialog can't be opened, though such changes will produce no effect until the Wave is changed to a repetitive type.
