Ask HN: What's the minimum-friction way to stream audio from a handheld device?

3 ポイント投稿者 killthebuddha2 年前9 コメント

I basically want a microphone with a button that starts and stops recording and live-streams the recorded audio to a programmable backend. I don't care if it's an app or a cheap-ish piece of hardware, but I have yet to find any single solution that satisfies even the streaming requirement.

Edit, for a bit of context: If there's no good solution, the prototype I'm thinking is just a Twilio Voice API endpoint that pipes received calls' audio into S3.

I think VLC can record and stream audio. I’ve never used this feature, though I did a quick search and it appears to be a feature.

This looks like a hard maybe, thank you!

I believe mediamtx can ingest the RTMP and present to a browser, via HLS or WebRTC.

You’re welcome. Sounds like what you want is RTMP or SRT. There are free solutions, for those, as well.

Does this backend have to be remote? Why not a Bluetooth (or WiFi?) mic or similar?

Hmm, maybe. I could run a server on my laptop and have the wifi/bt mic stream to it. But I really want this to work on the go, and having a running laptop, or Pi or whatever, at all times is kind of a non-starter.

Could a phone be the bridge/server?

Pipewire and a pinephone, librem etc?
