I had hoped from the title that this would be a summarized or edited cut of the salient points from these lectures. My limited resource these days is not bandwidth or disk space, but time.

> you can save some bandwidth in exchange for recording quality by using high compression of Speex algo
how about using opus, the comparison chart shows that opus is supposedly significantly better even at a lower bitrate.
Cool how you CAN compress 47 minutes of audio down to 1.6MB if you're willing to accept awful sound quality, sure. Why though? I mean, why thank the OP for their service? I don't get it.
The closer we get to pushing the limits of physics, while still expecting computing to be faster, higher resolution, etc. We should commend any efforts to make computing more efficient and less resource intensive.
What it saves in bandwidth, it pays in processing power.
But anyway, that still doesn't explain why posting these files is so cool that the post shot to the top of HN.
This article shot to the top because of at least three things:
1. It was well written.
2. It had to do with cool tech in a complicated problem space.
I only know those two.
