Default Frequency sweep tone generator that loops up and down?

I want a frequency sweep generator that can make a sweep from 20hz to 40hz then loop it. up and down from 20hz to 40hz to 20hz endlessly without any skips pops or clipping.
and I want it to be a windows program i can download or an online web software

does anyone know of any program that can generate endless seamless rising and falling frequency sweeps?

As I recall, many of the on-line generators can do something like this. No looping: Free Online Frequency Sweep Generator | OnlineToneGenerator.com
Looping: Signal Generator

Just make as loop of this in any of the freeware prongs, cool edit and similar successors.

You just need to tweak things to ensure phase coherence at the start and end of loop.

You can generate these with Audacity. Generate > Chirp.
Set frequencies. Then make the reverse, put them together.

Export as MP3, load into the playback device, and set to loop.

Doesnt work in audacity. it stutters and makes a loud click sound whenever the sinewave loops and declines in frequency and starts rising again and its impossible to get it perfect because audacity tries to fade the frequency in and out on its own but that causes a stutter because the sinewave doesnt perfectly match up at the ends
Not an option.
I need a program dedicated for this kind of specific task without any clicking pops stutters or artifacts in the waveform. I dont wanna have to do this manually. I wanna just enter a start middle and end frequency and just loop it up and down for however long I want.
and I dont want a payed or trial program or some giant program with a zillion extra features I wont use. if it could be an online web tool that would be even better then I wouldn't need to download or install anything onto my computer

I've never seen anything like that. Good luck. I could make one for you, but sounds like you want something to uses over and over and change.

no I just want it the frequency to rise up and down from 20hz to 40hz endlessly and smoothly thats all I want.
so it'll start at 20hz. go to 40hz then back to 20hz and repeat seamlessly without any stutters or pops
