[GreenKeys] Halloween Broadcast 2020 length

[Paul Heller]

For what it’s worth, here is what I do to the ITTY audio before sending it out:

Sample Rate = 11025 Hz
16 bits per sample
MONO (no need for stereo)

And I put on a low pass and high pass filter at 3000 and 1500 respectively.

These settings really helped to optimize the stream

So yes, the filesize and length is entirely expected, no surprises there. Though you make a good point-- the bitrate I have configured for the streamer and the recorder is unnecessarily high for simple RTTY audio (TUs aren't audiophiles), so yeah, I'm going to drop those down for the future. I can render the extant recordings down to 16kbps or so to make them more accessible for those with limited bandwidth/disk space (I'm lucky to live in an area and have a setup where both are in ample supply and forget my humble roots), but that's low on my list for the moment.
