Thanks for sharing this; it's excellent.
I'm happy to hear this - thank you!
I recently swapped to external desktop speakers from the built-in (very tinny) speakers in my screen and this sounds fantastic.
I have the same problem: my Amiga is connected to a monitor with useless speakers, so I need to resort to headphones (which I almost never do, as they are a pain to my ears) to hear sound properly.
For me the biggest let down of the Amiga is that the last Commodore (and Escom) machines had exactly the same sound capabilities as the A1000; this demo is another great example of those capabilities being really pushed.
Indeed it's a pity that there was no advancement in so many years, but the upgrade was not easy because Paula couldn't be given more resolution and frequency without making changes to the CHIP bus.
It runs nicely from my CF card attached to the build in IDE port which has a Sysinfo speed rating of about 1.8MB/Sec.
Ah, yes, 1.8 MB/s are plenty for the demo. I have a CF card connected to the IDE port as well, and with it 2 MB/s my A1200 can stream music at crazy frequencies like 200+ kHz - I didn't measure the exact limit of 100% correct playback, but the standalone playback tool breaks completely only at 322445 Hz (when the Blizzard 1230 IV is activated, that is).
