NavigatorUserMediaError

I was just trying to experiment with getUserMedia to record audio. It seems so painful to find anything out about how to do this on the web... Anyhow, I tried out your widgets but get a flatline in the visualizer even though it appears (if I look at the microphone input levels going up and down) that the mic is actually picking up audio. I'm using Chrome Version 24.0.1312.52, definitely have audio input enabled, on Windows 7.

i see you the step on the slider by 0.05. that means you are change the pitch by 1.025 each! 0.05 /2 is 0.025 + 1 = 1.025. if you want to change the pitch 5% then the step should be change by 0.1 each. 1.05 -1 is 0.05 x2 = step = "0.1"

What am I missing? This file is under the said directory but I'm not sure what the console errors are saying:

XMLHttpRequest cannot load file:/Audio-Input-Effects-master/sounds/cardiod-rear-levelled.wav. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.

effects.js:191 Uncaught NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load '/Audio-Input-Effects-master/sounds/cardiod-rear-levelled.wav'.

Thanks (for sharing!)

Hi peeps,

Based on this project I've made my own repository
with added functionalities (and modernisations to be compliant with modern browers, mainly Chrome).

Added options;
Record the audio from your live performance.
Choose a sound file instead of the microphone to add effects to.

The project: https://github.com/jonathanneels/Audio-Input-Effects
Test it here: https://liveaudioeffects.herokuapp.com/

Enjoy!

Thank you Chris for this wonderful library of effects. I am working on a project which kind of simulates an online DAW. I was wondering how I would be able to automate effects which cannot be built using nodes which are "AudioParam" (Since only audio params possess the ability to schedule values on a timeline). For example - distortion or pitch shifting.

Thanks,
Anand

I managed to make the script Firefox compatible, by replacing those lines by:

  navigator.mediaDevices.getUserMedia(constraints)
  .then((stream) => {
      gotStream(stream)
  })
  .catch((err) => {
      alert('Error getting audio');
      console.log(err);
  });

I can’t really PR because I can’t get adapt gotSources() properly with MediaDevices.enumerateDevices()

Hello,

I noticed that the shaders are not loading because of a CORS error when accessing the app via http. The requests for the shaders are done with https. It is easily circumvented by just accessing the demo site with https, but since Google links to the http site, it may be desirable to support it as well.

XMLHttpRequest cannot load https://webaudiodemos.appspot.com/input/shaders/sonogram-fragment.shader. 
No 'Access-Control-Allow-Origin' header is present on the requested resource. 
Origin 'http://webaudiodemos.appspot.com' is therefore not allowed access.

Cheers!
