[Demo] Chrome does not allow insecure sites to access the mic.

[Carl Smith]

The demo site cannot access the user's microphone in Chrome unless its over HTTPS.

When you click on the Line-In link, nothing seems to happen, but looking at the console, it causes an Uncaught Error in compiled.js at Line 585: SecurityError: Only secure origins are allowed (see: https://goo.gl/Y0ZkNV).

That link expands to www.chromium.org/Home/chromium-security/prefer-secure-origins-for-powerful-new-features.

I manually changed the URL to start with HTTPS, and everything works fine, but the link in the README uses HTTP, and it's not obvious to users why it then doesn't work.

Adding a note telling users to ensure they're using HTTPS would work, but it should be fairly easy to detect the protocol and redirect the user to the secure version with clientside JS.
