I really want to know how he solved this problem, which I also face:

>last year i bought a Rodecaster Duo to solve some audio woes to allow myself and my girlfriend to have microphones to our respective computers when gaming together and talking on discord in the same room without any echo

[hhh]

the rodecaster can connect to two computers, and we are both generally in the same discord call. so we have both microphones routed into one input for a computer, and the other person joins with their mic muted and the audio just comes from one client. since the mixing is local there's no echo. email me if you have more questions :)

So both mics will pick up both people (at least somewhat, in the same room) - but because there is no, I assume 20-100ms latency going through the system, to discord, and back - it avoids a slight difference in timing of the two mics picking up the same sound slightly differently. Is that right?

Very cool!

[hhh]

correct

also the audio output of each computer is routed thru the box as well, so i can mix my girlfriend’s computer into her headphones as well as my microphone, so she can hear me with noise canceling headphones, or turn off my microphone if i’m working so she can do stuff without my mic in her ears.

Or if she’s watching a movie or something I can also add her computer audio to my headphones. There’s even a separate audio output for host 1 where you can put ‘chat’ on, like discord on a dedicated interface, so that your application audio is clear and isolated. It’s hella expensive but it really is a great device

Not in the same league or form factor, but I have an old Jabra 65 headset, and the noise canceling is amazing. I can be playing my cello while unmuted on a call, and nobody can hear it.

I know headsets aren't everyone's cup of tea, but a mic close to the source (your mouth) with good noise canceling is a solid solution.

Why connect it to both computers?

It saves on rewiring stuff. Maybe there's only one person talking today. Maybe they're using PC A, or perhaps they're using PC B instead.

Or maybe there's two people in the room, each on different channels altogether. In this case the other person is just uncorrelated background noise instead of a persistent echo.

Or, in-context: There's two people in the same room, both talking on the same Discord channel.

Anyway, audio routing is useful. Being able to route audio with two different PCs is a pretty neat feature of the rodecaster.

I get it! Thank you that is genius.

I recently vibe coded a jack mixer in Rust. It can ingest and relay audio via LAN. I have around 40 ms latency, 50-60 ms if relaying via wifi.

It would solve the issue in a similar way. One pc runs the mixer. The mixer has an input channel for local mic.

Other PC broadcasts their mic to the mixer, which comes in as 'channel 2'.

You can even have music playing on your local PC, either the mixer or broadcaster creates a local sink.

It's all then mixed in the mixer, there's 3 outputs. You could say use the main out to send to discord.

And the monitor line would be used to output Discord audio, which can then be relayed to the other PC for realtime listening.

Doesn't a headset with directional boom microphone do the trick? I may be misinterpreting the problem statement though :-).
