:wave: Motion detection using the doppler effect

doppler's Issues

Still audible frequency

For me, page outputs a high pitched whine (VERY Audible).

Demo Url does not work

I was showing this to some people the other day and ran into a small issue getting it to work.

It turns out getUserMedia() doesn't work from non https:// urls.

Luckily the fix is as easy as changing the website for this repository to https://danielrapp.github.io/doppler/

Proper configuration of device levels

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?

Tone suddenly disappears, high frequencies don't work in other tabs and applications anymore

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?

Publish to npm :)

'doppler' is available on npm! https://www.npmjs.com/package/doppler

Refactoring proposal

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)).

Lot of noise and flickering

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.

Unable to run

I'm trying the demo, got the following errors in browser console, unable to get it work. Please advise if any browser compatibility req. thx.

Link to Paper is broken

Doesn't work on the new chrome as some functions in the doppler.js are deprecated and chrome audio policy has also changed.

publish this to bower and npm?

Doesn't work with WebRTC support in Safari 11

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.

Distinguish Channels ?

Would it be possible to somehow distinguish left/right speakers ?
