Deneb USB Audio performance?

[mechy]

So I was wrong about the drivers but about as unusable as playing mp3s in general without dedicated hardware on the miggy ?

I play them just fine using a csppc with mediator and sound card. no dedicated audio processing hardware(i mean the sound card does not unload the cpu to play).

When we say we play mp3 just fine I am surprised.  I take it we are not talking 320 at 44 in stereo whilst doing anything else ?

Yea,we are talking that. the mp3 playing is offloaded to the 604e/233 for playing while the 060 under os3.9 takes care of everything as normal. multitasking is no problem. i also run workbench in 1920x1200x32 and its quite fast with the radeon. note this is for a csppc and A4000, not necessarily the blizzard ppc which is way slower/bottlenecked.
With the zoram and 256MB extra +128Mb on csppc  i never run out of ram either. Flac,ogg etc also work.

All this has worked fine since mediator was introduced and you could use a sb128 or other sound card(with csppc accelerator of course). Zorro3 usb is quite fast with the deneb also.

and before this circa 1995 was the A4000 with 040/40 warp engine and Picasso IV with Concertio sound card addon for it.24 bit gfx and nice sound.

Another easy way to play mp3 on amiga with nearly zero load could also be the masplayer.

where have you been man? :pint:

I suppose I should have also mentioned that I am running a P-IV at 1152xsomething, and a whole bunch of patches to take stuff out of Chip RAM.  It probably makes a little difference.  As well, the library used to decode the MP3 in the first place probably makes a difference.  I am not certain which I am using, most likely whatever AmigAMP uses by default.  Again, high bit-rates ain't cuttin' it on my system.  128kbps is the highest I can reliably play whilst doing other things.  192kbps stutters sporadically, and anything higher you can forget about altogether.

the piv gets really slow anything over 1024x768x24(its not fast in this mode either)-800x600 would probably be noticeably faster. decoding libs will make a difference.  
what accelerator and on what amiga are you doing this? is the deneb in z3 operation?

Last time i tried was on my 030/50 and was terrible.

Never tried on my ppc 175/040 because had much more capable hardware and software for playing mp3 i guess

030/50 can do it with the right software setup,but you won't be multitasking much if any.

i assume you meant a blizzard,and thats a really slow card(blizppc is 32bit throughout where the cyberstorm ppc is 64bit on the ppc side) csppc is much faster. i doubt the blizppc at those speeds would do much better but i could be wrong. the 1200 is full of bottlenecks and you cant expect much from the horrible unbuffered ide.
