Insert - FM Sound

Use this command to insert FM-modulated wave data.

FM‰¹Œ¹

Carrier Frequency

Determines a pitch of sound.
440Hz represents "A" note.

Modulation Frequency

Use this option to adjust the speed of vibration.

Deviation Frequency

Use this option to adjust the depth of vibration.

Amplitude

Determines the amplitude (level). Drag the slider or enter the new value in the Amplitude box to change the amplitude.

Sound Length

Determines the duration of the FM sound you are inserting. Use the drop-down list on the right to specify the unit.
When you choose Effect - Insert - FM modulation with a range of waveform selected, the length of the selection is displayed in the Sound Length box. If you change the value in the Sound Length, the waveform selection will be replaced with the specified length of FM sound.


Formula used for FM modulation

sin (wc * t + wd * sin( wm * t))
t:
Time
wc:
Carrier frequency
wm:
Modulation frequency
wd:
Deviation frequency
