I played with the doppler tool a bit, when suddenly the once clearly audible tone disappeared and the motion tracking didn't work anymore. I didn't think much of it, but now, even after a restart, the higher frequencies on any other website and application don't work anymore. Does the tool actively block the frequency or is it likely, that my speakers are broken?
Enabling the legacy webrtc api in the developer menu allows the demosite to prompt for mic access, but once granted, the demo doesn't output the high frequency tone or display any spectrals or seem to react to sound in any way.
For me, page outputs a high pitched whine (VERY Audible).
I am getting a lot of noise and flickering.
Basically I am unable to use the library. I had to turn of noise cancellation for it to start giving noisy readings. But switching it on, renders it useless.
Would it be possible to somehow distinguish left/right speakers ?
Glad to see such a nice idea implemented!
I came from this page: https://danielrapp.github.io/doppler/
I own a PC where camera with mic is plugged as usually - at the top of the [middle] screen.
When in page-scroll mode I move my hand, page scrolls down, but when I move hand back - it scrolls upward to the same interval.
I think this is related to either camera/speakers position or their levels.
What do you recommend to tweak?
'doppler' is available on npm! https://www.npmjs.com/package/doppler
Hi Daniel,
Thank you for building doppler!
It's one of the projects that have inspired me to go speak at a conference about unconventional ways to transmit data and input. I will use doppler on stage, of course giving due credit to you and the paper authors.
I made some updates to a fork of the project, mainly to suit my needs during an interactive demo on stage. The changes introduce the ability to turn doppler on/off, update API references and expose callbacks. I'd like to contribute my changes back to the main project, but I batched them together in one "refactoring" branch rather than multiple atomic commits.
Please have a look at the diff and the comments at the end.
Are you open to accepting this batch of changes as a pull request?
They do introduce breaking changes for existing demos, but I'm willing to help update them (I replaced init(callback)
with start()
and on('sample', callback)
).
