MP3 playback on Paula...

[Jose]

What program are you using ? Are you using the 14bit driver?
You can also have up to 56khz if you're using a VGA screenmode (31khz), and this in combination with the 14bit thing. Sound is pretty much CD quality.
If you're using a non VGA screen mode you'll probably only be able to play'em at 22khz. These support up 28 or 27 khz if I remmeber... but you have to halve the frequency hence the 22khz. Even this is not that bad actually.

Ahh, and don't forget to use all that and calibrate it. It also makes a difference. These all together give very good sound. Amazing the stuff that has been pushed out of Paula isn't it? To calibrate the Paula driver use the Cybersound system available HERE

IIRC I think the Paula driver comes on the AHI package but I might be wrong. There were players that also supported 14bit directly but I know of only one that also plays MP3 and that's Songplayer. Other more recent ones (and also cooler with more features and better  looking, but more CPU intensive) also support all that stuff but through the AHI sound system.

The AHI home page can be found HERE

Don't overlook the calibration, it makes a noticeable difference IIRC. Good luck, and let us know if Paula rocks or not after all that :-D
