I just watched a tutorial on how to create tone (with or without bars)...and it was like 14 steps.
In Premiere you simply click bars and tone and they appear. Does anyone know an EASY way to generate tone in Resolve??

In the Edit page select the type of bars you want in the Effects/Generators menu and place on the Timeline. Drag it to the length you require.
In the Fairlight page add a mono or stereo track. Click on Fairlight at the top of the page and select Test Tone Settings. The Oscillator window will appear. Click on the three dots top right of the window and click to open the Patch window. Patch the Oscillator to the new track and record.

Dual screens used for clarity.

Back in the Edit Page this is what you see. The level in the Main 1 meter is 3db down which is correct when sending a centred mono signal to a stereo output. They will match if you place the tone on a stereo track.

Thanks. I appreciate the info. But. As in Premiere Pro, you right click the mouse and hit bars and tone and there you have it. I keep telling people Resolve is convoluted and they keep telling me its not. LOL. Bars and tone is so basic how is there not a one click solution? Same as trying to save a simple single still frame. Again, in Premiere it's literally a single one button click, in Resolve you have to go into color and blah blah blah. Oh well. Looking forward to Resolve 17.
Again, thank you.

I just went through all the steps and finally got it to work. NO THANK YOU! Wow....all those steps just to create tone!???? Blackmagic engineers really need to spend a week with some real editors and get rid of all this nonsense. This should be like a 3 step process at the most!
The engineers already hate me,...but you know, the customer is always right.

As a matter of curiosity, what exactly are you using bars and tone to achieve?

I would imagine he's adding 2-pops to timelines.

But bars and tone and a 2-pop aren’t the same thing. In any event, I don’t understand why someone would want to make a 2-pop over and over rather than do it once or just for fun. There’s also no magic in 1Kz, which is readily available anyway. Hell, for a 2-pop tone I’ve used dinosaur sound effects just to play around.

I asked Allen what he’s trying to achieve because it isn’t obvious.

Just to balance my speakers and to make sure their placement is exact. And their volume levels are exact.
The point is, this should be soooo simple and its soooo convoluted.

It sounds like you're trying to set up your speakers for sound mixing. If so, there are lots of discussions about that on the internet. It's party objective, partly subjective, and it isn't particularly hard. However, "bars and tone" have nothing to do with the process. Most sound engineers mixing music wouldn't even know what "bars and tone" is

Bars and tone are a reference for checking your reproduction chain. Back when using videotape for broadcast all masters had bars and tone. Also all audio masters had a set of alignment tones at the head before the programme material.
Calibrating your audio monitors is a different story and should be done with pink noise and a sound level meter. A 1k tone is not the way to go for that.
If a sound engineer today does not understand the use of tones what a sorry state things have become.

If that's what Allen is trying to do, and he doesn't own a sound level meter, this organisation makes a free app that turns a smartphone into one: https://www.cdc.gov/niosh/docs/2018-124/default.html

The app is pretty well-regarded. On iOS, it's called "NIOSH Sound Level Meter". Don't know about Android. NIOSH is part of the US Center for Disease Control, so the app may not be available outside the US. However, there are lots of other sound level apps.

Yes, people generally use pink noise.

For monitor calibration the meter needs to have c-weighting and a slow response.

Ideally, one owns or rents a quality sound level meter. Not everybody is able, or willing, to do that. In this case, we're talking about someone who appears to be trying to calibrate monitors with DaVinci Resolve.

FYI: the NIOSH Sound Level Meter is available outside the US too.

BTW, anybody who wants to download pre-made audio test tones for free, here's a link:

Sorry to revive a now almost 4-year-old thread but yet another coming-from-Pro-Tools request:

I'd love to have a keyboard shortcut that allows me to generate 1kHz sine tone for the length of the timeline selected on a given track. Patching/use of bar generators is super clunky fwiw.

AndreBlaze wrote:I'd love to have a keyboard shortcut that allows me to generate 1kHz sine tone for the length of the timeline selected on a given track. Patching/use of bar generators is super clunky fwiw.

Well, it takes 10 seconds to download the tones I have up on the net, and less than that to drag it to a timeline and use it in a project.

Yeah you're right it's really not hard at all don't get me wrong - and once you have it you have it.. but it is nice to just be able to instantly generate it with a key command

What a ridiculous amount of steps just to create tone and the fact that the final step is to record this tone in realtime makes absolutely no sense. Add a generator in the Edit window in Effects just like there is for Video Generators.

Sure would be nice to have audio generators like this. Not a big priority but something I’ve used and appreciated in other NLEs.

Tone is the wrong signal to balance speakers.
You need a wide band noise signal like white noise or pink noise.
Tone will create standing waves and phase issues and will not work for speaker positioning & level matching.

I have a question about the tone generator in Resolve Studio v20:

When I'm recording to the track, the tone is continuous. But after I'm done recording and I play it back, it's gated--tone, silence, tone, silence, tone.. what could be causing that?

Could be almost anything. Without more info it's impossible to guess.

I'm just following the procedure shown in numerous YT videos.. they're all pretty much the same... set up the tone generator to 1KHz, patch it into audio track 2, then arm track 2 for recording and press record. The tone is audibly continuous during recording, but when I play it back, it's on/off in 2 second intervals. Baffling.

Amazingly, I have pink noise and white noise tones up at the download link as well.

Which version of Resolve? macOS or Windows?

Is the waveform continuous or is digital black apparent?

Windows version. The timeline shows the waveform switching on and off, too.

Just tested here and it is working. Pic shows continuous 1min 25secs of tone which plays without breaks. Also shown is the patching used.A 1khz tone is normally used for checking levels and balance on your device meters. Speaker calibration uses white or pink noise along with a SPL meter to balance the reproduction of the speakers themselves to a known standard.

I tested again. Patched the oscillator into the bus track 2. During recording, I see a continuous tone being painted on the track and meters are showing continuous tone. When I press Stop, the continuous tone is replaced by this on/off/on/off tone.





This appears to be a Dual Xeon CPU conflict with Resolve. I tested this on my i7-9700K-based system with low RAM (only 64GB) and it records and plays continuous tone. So perhaps Resolve has a problem with NUMA nodes because my main editing workstation is based on multiple CPUs (server motherboard) and large amount of RAM.

I just tried recording voiceover on a track on the Dual Xeon workstation and the voice is continuous, but sounds robotic, like something is wrong with the sampling.

I found the problem:

DaVinci Resolve Studio 20 b1 is not compatible with ASIO. If I switch to "system audio", it records continuous tone and voiceovers are not distorted.

ASIO needs some work in DR.

Not reproducing the issue on Windows 10 with ASIO. Are you using Windows 10 or 11?

Which ASIO device and driver and is configured on that system?

Windows 10 here. Auzentech X-Fi sound card.
