Tuning Quiet for Reliable Low Bitrate Whisper #23
Comments
@brian-armstrong if you have time, would really appreciate an answer :). Is it possible to do this with a quiet-profile / changing parameters? If not, why? Thanks! |
I have experimented with this some but it requires a new mode of modulation that's not currently in quiet. I have a branch that adds the new mode, and I should look into merging it in. In general the answer for why something isn't possible is that I have a day job and can only work on this in my spare time :) |
Haha I understand. Thanks anyway for quiet - it's such a cool library. If you merge / publicize that branch please let us know :) |
Hi @brian-armstrong, were you ever able to get this branch in? I was looking and I didn't see it. Thank you |
He may be referring to this, tho not sure... https://github.com/quiet/quiet-beacon |
I want to broadcast a very low bitrate of 16-32 bits per second for source identification (as opposed to large data transmission), ideally continually, while staying as inaudible as possible. Which settings should I be tuning?
Have you explored lower-end bass frequencies for this purpose, perhaps infrasonic? And could I consider stretching a symbol over a much wider bandwidth at a low energy to ensure delivery?
(My background is systems & signals, but haven't done much modulation in a while.)
