Ever wished you could use your phone mic from your linux computer (exposed as a PulseAudio source)?
This provides a simple solution to this problem, all wrapped in a single staticly-linked binary written in rust without unsafe code.
cargo install --git https://github.com/russelltg/web-micRun web-mic, and connect to it on your phone with https://<your ip>:8000. Note the s--it must be https.
You will see a security warning, choose "advanced" then "proceed to xxx". If you are curious about this warning,
see below
The Web Audio APIs only work in secure contexts, so it runs using self-signed certificates.
However, these certificates are cached (in ~/.cache/web_mic), so you should only have to bypass the security warning once.
At least on android chrome, it seems to throttle the capture worker when the phone is locked or similar, so you need to disable the screen timeout. I personally have the setting in developer settings turned on to not timeout the screen when its plugged in.
This app should obviously not be used when low latency is required. In my limited test, I got around 100ms of latency, which is fine for VoIP.
Unfortuantely, currently you can't just put your local IP in the phone browser, as it defaults to HTTP, and warp currently cannot upgrade from HTTP to HTTPS on the same port.
This could be worked around by opening a new port that just accepts redirects to https, but for me a bookmark fixes that problem fine. If someone wants to implement that PRs are welcome.
This app is mostly for personal use, so reach out to me before spending a lot of time on a feature. Otherwise, pull requests are welcome!
