These sound terrible. The lowest-quality audio from Youtube is about 10x the size (which is still small), but at least it doesn&#x27;t sound like a rescued wax cylinder recording from the turn of last century.<p>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.

Thank you! these are very cool.<p>&gt; you can save some bandwidth in exchange for recording quality by using high compression of Speex algo<p>how about using opus[0], the comparison chart[1] shows that opus is supposedly significantly better even at a lower bitrate.<p>[0]: <a href="https:&#x2F;&#x2F;www.opus-codec.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.opus-codec.org&#x2F;</a><p>[1]: <a href="https:&#x2F;&#x2F;www.opus-codec.org&#x2F;comparison&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.opus-codec.org&#x2F;comparison&#x2F;</a>

I really like the idea, but I find Speex distorts the audio way too much in a way that makes it hard to understand afterwards. I&#x27;m willing to sacrifice as much quality as I can as long as the speech remains easy to understand, but after that, any space savings aren&#x27;t worth it.

I cannot recommend highly enough, You and Your Research. Great life and career advice from a great man near the end of his life.<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=a1zDuOPkMSw" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=a1zDuOPkMSw</a>

Thank you for your service, sir.

Why are people thanking the OP?<p>Cool how you CAN compress 47 minutes of audio down to 1.6MB if you&#x27;re willing to accept awful sound quality, sure. Why though? I mean, why thank the OP for their service? I don&#x27;t get it.
