Davinci Resolve’s Fairlight sound editing section is capable of creating sound signals in specific hertz.
1. Create Timeline
First things first create a timeline to add audio tracks. To do so, follow the instructions on Davinci Resolve - Create Fairlight Project article.
2. Audio Routing
In order to generate signal we need to define an input virtual device using the sound mixer on the right.
- Click on the sound track that you want to generate signal
- Click on “No Input”
- Select “Input…”
You will see Patch window pops out. On the left there is Source, on the right Destination. We use “Signal Generator” as sound input source and route the input to our selected Track 4.
Select one of the signal generators on left.
Select Track 4’s left and right channels on right.
Hit “Patch” button on bottom right.
3. Arm The Track For Recording
After you “Patch” the routing, close the Patching window. Goto your track (mine was Track 04) and enable “Arm For Recording” toggle shown as R. You instantly hear the signal depending on the type of generator.
4. Generate Test Tone
You can adjust the parameters of the relevant signal from the top menu “Fairlight.” Click on “Test Tones Settings…” menu.
You can adjust parameters of “Noise” signal from the right section on pop-up menu window. You can adjust parameters of the sine signal from the left menu as follows.
5. Record The Audio Signal
Hit record button on the Timeline panel to instantly record the signal to the armed track. After you are done with recording you can disable R (Arm for Recording) option to make the track silence when you are not playing anything.
