I should add that's a 341KB opus file at 16kbps.
The flac file it was derived from (found here: https://archive.org/details/78_st-louis-blues_w-c-handy_gbia0030859a/St.+Louis+Blues+-+W.+C.+Handy-restored.flac) is over 60MB.
I went from over 60MB to just over 1/3 of an MB.
And a close listen with some good headphones or speakers will reveal some minor differences on the compressed file, but holy shit it's 341KB.
Here's Kid Ory's Creole Trombone as a 413KB, 16Kbps opus file.
The "original" here is a pirated recording released in the early 20s of an impossibly rare jazz side from the first black jazz band from New Orleans to cut a record.
Piracy paved the way for preservation.
Now it's in the public domain, and I've compressed it down small enough that it fits more than one copy on a floppy disk.
I've made it small enough that it can be transmitted by basically any means.
It would take a little under 3 hours to transmit this over a standard hayes modem, or to store it in Kansas City Standard.
22 minutes to transfer at 2400 baud.
Faster than real time on standard 56k dial-up. (a little under 1 minute!)

And here's St. Louis Blues
Half a megabyte for 6 minutes of music.
You'll have to download them and play them locally, until I write a blog post that embeds a player, but they are what I said they were, and they sound find.
@ajroach42 that recording is 1925. Handy is from Florence and I’ve heard it a thousand times, and used to do lights and sound for a play about him yearly. Also been to his house where they have an original I believe
@DoctorDeathray cool. Will be in the public domain soon.
