Alright, I wrote a blogpost about my adventures:

This doesn't have much new compared to my posts from this weekend, but here they are ordered and coherent.

I also posted some audio samples:

Keep in mind that both samples will sound pretty much horrific, but also that each sample is around 100kb for more than a minute of audio.

I prefer the Opus file to the mp3 file, as it's a little less muddy during speech (but ruins music.)

Something to consider re: - Average dialup bitrate (towards the end of the dialup era) was 40–50 kbit/s, right?

These files are averaging about 9kbps.

You could stream a on a dialup connection without saturating the connection.

If that sounds like a ridiculous thing to care about, consider that the easiest way to increase the distance over which you can transmit a signal is to decrease the transmission speed.

So, if you were hypothetically trying to build a new network that transferred media over long range radio connections, phone lines, and sneakernets, very small file sizes would be very beneficial.

@ajroach42 Another way to look at it: 9 kbps is slow enough to transfer over 9600 bps AX.25 packet radio, in *real time* (although you're not using stuff ideally suited for degraded-link comms, so packet loss would be nasty, especially given the notorious unreliability of 9600 AX.25).

@ajroach42 Not enough thought gets put into the fact that we'll someday be wanting to have conversations with Mars.

@emsenn @ajroach42 There was a Sci Fi story on that score. To improve communications, talk like women can. Both sides talk continuously and answer questions as they arrive as well. It removes the limitation of waiting a few minutes delay to answer a question by keeping the information flowing continuously.


Yeah, isn't that how FT8 call works? That can work below the noise floor by averaging across a repeated signal.
