I thought that SB128 and 040 can play mp3s!!!

..well, I am quite dissapointed with the "results" I get on my A1240 with SB 128 in Mediator - AmigaAMP just can`t play mp3s properly!!! I thought it would not be a problem for a soundacrd correctly installed in system! Btw my Amiga doesnt want to boot just now for unknown reason.. great, it sux all..

would help if you explained your problem a little better. "just can`t play mp3s properly!!!" doesn't tell us much. Is the sound quality low and grainy? Skipping and jittering?

If .mp3s play but quality is low then run sys:prefs/ahi (AHI prefs prog) and try increasing the card's frequency setting. default is usually quite low, so just whack it up fully (around 48KHz, i think). see if that helps.

if the quality is ok but you have pauses and skips try increasing the buffer settings in AmigaAMP.

..thanx, ok, I experience pauses and skipping while playing a song, changing buffer doesn`t seem to help as the best results I get with 64 KB or 32.. I thought, that playing mp3s with a soundcard is not so CPU time consuming! I almost got better results playing mp3s through Paula years ago.. IMO it is the mpega.library problem.. is there any other possibility or should I try a newer version?

..hi there, thank You all for explanation, well, it seems that I am going to have another free PCI slot, becouse there is no need for me to use SB128 then anymore.. :angry: :lol: ..btw TV Card went off last week as I have TV-Tuner in LCD now (but I don`t use it anyway).. :-P ..ok, then I go back to Paula 14 bit output and will use just MpegaGUI for mp3.. (maybe..) thanks anyway

Something is wrong with what you have for sure.
As when I run Amp or AmigaAmp or even Songplayer latest version, I play MP3's with no problem.
I run a 1200 with Mediator SX, SB128 and Apollo Turbo at 40Mhz with 32 meg Fast ram.
AHI is setup correct.
I hope you get it up and running soon, as with your setup it should run MP3 with no real problem
If i can do it on my setup up, you should do it on yours.

..If only I could get an idea WHAT is wrong in my system..  :-(
..AHI is set correctly (IMHO), I have chosen SB128 HiFi 16 bit stero ++ modes, but I think that bottleneck in my system  (beside the CPU) is 4xEIDE disk controller.. simply IDE consumes so much CPU power..

Actually, reading the compressed data (mp3) off the disk takes less time than transferring the decoded sampledata (stereo 16bit) over Mediator. A1200 Mediator has no DMA to amiga system memory, it's all CPU poking and peeking.

However, in this case the obviously most time consuming part is the mp3 decoding. SB128 can't speed that up.

..I must agree. 060 would make significant difference? I guess so.. but mp3 playing is not my priority in Amiga usage.. (well, I don`t know what is it actually, as I just watch demos and play around with workbench when I get some time)

..well, this discussion is quite pointless for me now as I use 3100+ Athlon64 PC on everyday basis for everything needed.. SB 128 will go off my Amiga in the weekend, so there will be some more fresh air again ;-)

btw what OS do You use with that G4?

theres nothing wrong with your 040 system!

swift240 was speaking about his Apollo 1240 at 40Mhz... its all another matter with a 040@40Mhz!

..why it is all another matter when I have got Blizzard 1240 at 40 MHz??

[MASACREWILL]

..very interesting, very! If I wasn`t quite satisfied with my PC system, than maybe, maybe.. ;-)

i didn't noticed you have a 40 Mhz CPU.

Anyway follow what i wrote about software.

..yes Sir.. ;-) thanks

[MASACREWILL]

..err, mine too, but its overclocked (233*9) and I play games quite often, so it has a right to be a heater ;-) Anyway I use some of those Zalmans big copper CPU coolers, so it is not so noisy actually.. but nothing beats a good water cooling anyway.. (thats another story..)

..who actually sells Pegasoses?  :-D

[MASACREWILL]

..thanx, I also found Czech Pegasos User Group at pegasos.jinak.cz..

[MASACREWILL]

..and what about choosing Warp 3D decoder in the Amiga Amp instead of mpega.library? Would this help? (I can`t try it untill thursday..) :roll:

[MASACREWILL]

..well it is the same thing.. or is not? :-? Or is WarpUP just a PPC thingie? Ahh, I see..
