ACA1230/56 - what's the deal?

A 030 won't be enough to play 44Khz 128kbit MP3 in stereo. You would need a 060 in order to do that comfortably.

you don't need a 060...a 040/25mhz can play mp3 in a perfect way

What do you understand as "perfect"? 22Khz is not "perfect" for me. With a 040/40 you'll reach 44Khz mono without problems but for usual 128kbit, 44Khz MP3 you'll need a 060 (and it will have plenty of power remaining available, I used to record CDs from mp3 at almost 2x IIRC)

on a 040/25 you will reach 22khz stereo.. it is not perfect but sounds very well
anyways on a 040/40 overclocked to 50mhz will reach idem speed of the 060/50  
so your argument is not valid ...lol

like said Crumb higher bitrates requires more cpu power
you can try to encode at 64 kpbs which sounds pretty well...it will require less cpu power...also the mp3 file will be small
also amplifier it is a bad mp3 player for a 030...eats lot of cpu power
for 030 I recommend songplayer or splayer both in aminet

22Khz doesn´t sound "very well" IMHO. Standard 040/40 certainly isn´t enough for playing 44Khz Stereo MP3. So if you want 44Khz Stereo MP3 you´ll need MORE than a 040/40: a 060 (OK, an overclocked 040/40 running at 50Mhz may be enough according to you but most 040/40 run fairly hot and although I know overclocked 040/50 exist I never used one)[/QUOTE

yes the 040/40 can be overclocked to 50 mhz using a 100mhz crystal and adding a biggest fan
it reach idem speed of the 060/50 mhz on integer... about 39 mips on sysinfo and of course you can play mp3 at full speed
the fpu also overclocks but remains a bit slower than the 060...the 060 have a faster fpu module

@laserback

do you know what are the best 040/40 revisions? I have a WarpEngine and I guess it would fly at 50Mhz but it already gets pretty hot.

?

I done the overclock long time ago on the apollo 1240/40 and I can't remember the revision but I'm sure it was an old 040 revision cause the most recent 040 does not requires fan
maybe the biggest problem you will find on your warp engine is to found compatible memory simms with the overclock...I remember that not all memory simms worked well with the overclock...I tried some 16mb memory simms until I find one that worked fine
I calculated that only the fastest simms will work....edo or 60ns simms
