Is it possible to play MP3's on an Amiga 3000T with a
stock 030 25mhz, without the sound constantly starting
and stopping?
Thanks
Chuck

Short answer: no
Long answer...
Yes it is, with one of two MP3 playback programs.
(1) Songplayer
You must set the quality settings very low and play in mono.... paula 8 bit.
(2) Prayer2
As above with low quality settings.
With either, don't plan on doing ANYTHING with your Amiga while playing back MP3.... don't even move your mouse.
But it will work :)
-
It's possible, but playback quality through
Paula - even 14bit - is atrocious. I couldn't
handle more than a few minutes.
-
So what is the minimum processor/speed combination
to get it to work with decent sound?

YOu could get a hardware decoder from eyetech expensive though link here mp3 decoder (http://www.eyetech.co.uk/search.php?SearchStr=&SearchCat=AMAU)
And a lot of info and the software is here http://home.snafu.de/dcr/ (http://home.snafu.de/dcr/)

I've got a MAS Player for sale.

A fast 68040 - preferably not the stock A4000 68040 - should be able to do stereo 44 kHz with careful planning, if Paula is used. For a soundcard, you really need a 68060, because there is more data to copy and it won't go all that fast. Unless you are lucky enough to have a Delfina: 68020 is enough then. :-)

MP3s are best played on PCs and home DVD players and on MP3 players. The Amiga has its own forms of music that works really well. Mod and smus are examples of Amiga music formats. Do PC stuff on a PC. Do Amiga stuff on an Amiga. Do not try to mix the two. Remember, the Amiga is a German computer. :-D

DoomMaster: "MP3s are best played on PCs"
Edit by Kees - Personal insult
How does the Amiga being a German computer have anything to do with it, in fact how/since when was the Amiga a German computer exactly?
Macs? Portables? Amigas? My Amiga 1200 060 with Soundblaster (using Songplayer) plays MP3s very well thankyou (actually better quality than on my DVD player), and I can use the computer for my everyday stuff without the MP3s skipping or slowing up.

@DoomMaster
The most sh1t filled sentence I've ever read.
If MP3's for "PCs", why has LAME been ported to WarpOS? Why are there truck loads of MP3 decoders for AmigaOS? Why does MakeCD support on the fly MP3 decoding?
That's like saying GL should only be used on Windows, or the ping command should only be used on Unix.
Edit by Kees - Personal insult
Sorry.

That's like saying GL should only be used on SGI
:lol:

I've read somewhere that the first versions of Songplayer (the ones that don't use the mpega.library) decode mp3s faster than later versions, why I don't know.

So, if I only own an Amiga, I couldn't play mp3s even if I have a player for them, only because I have an Amiga. Hmm, is this a new form of racism? :-(

@DoomMaster
May I remind you, MOD and SMUS are both tracker based formats. MP3 is streamed. Two completely different things. How you can compare MOD and SMUS to a streamed format is beyond me.
Gonna reply? Heh. Probably not. They never do.

Use Prayer 2 - on 030 50 mhz and low quality its ok but it could be better.
If You have an DVD player with mp3 than use it or a PC if U have or buy the !MAS-Player! hardware ;-)

for MP3s at full quality, you need at least 040 at 40 Mhz.
With my 040 at 30 Mhz, i can play with SongPlayer 1.45 (the lightest one) at low quality Stereo with Paula and at MID QUALITY MONO with the RepulseGold card through AHI.
So i doubt that you can listen MP3s decently on your system.
Ciao

Interesting post. I've read but I just see that you've got an 25Mhz version of an 030. Because I would mention that I played mp3s for years on my 030@50. Just play it on half rate (22050hz), mono (saves a lot of speed!) and then try the best quality setting. AFAIK was it option 1 (0,1,2).
Good luck, let us know :-D
Oh and, i use amplifier and/or prayer. Those are the fastest. Don't let you get distracted by the programmer of Prayer which claims she's a photomodel. It's just a "marketing" strategy ;-)

If you dont want to get a beefier system I'd say one of those parallel port MHI decoder things would be good. Or perhaps a delfina DSP based soundcard (IIRC there were mpeg decoders written for its DSP).
For CPU based decoding through paula, forget it, unless you can live with 11kHz 8-bit mono.
Under 680x0 you really need at least a fast 040 to get any joy. My 25MHz 040, which is what, 4x faster than 030 @25MHz, can manage 22kHz 14-bit stereo, but it uses so much CPU (havent tried a libmad based decoder yet, might be better). For better quality an 060 is essential. Lukily for me, I use a BlizzPPC and can use ppc based decoders such as amiga amp which works a treat (apart from that time I mistakenly 'upgraded' to AHI v5)...

So... What chance would my a500+ with 2mb chip ram have of playing 44khz stereo mp3?
heh Heh :-D

Assuming your parallel port can move more than 20k/s and there is a 68000 based driver then probanly very high with a MHI based decoder... ;-)

Of course it is ! Even with a plain 68020 14Mhz ...
Well ... It's possible, not by the most direct way ...
Try
14bit-and-mp3.lha (http://wuarchive.wustl.edu/~aminet/docs/misc/14bit-and-mp3.lha)
A guide I made on this matter. Maybe it suits you.
(BTW : my e-mail address on the guide is now obsolete)

Thanks everyone for all the good info,
I believe in the interum, I'll play around with the
2 software players mentioned, but I'll probably
be looking for a Delfina card on eBay or maybe
building that MAS-Player thing.
I can already play MP3's on my B/W G3 MAC and my iBook
but I would like the amiga to do it as well.
Is it possible to convert an MP3 to an audio format that
the amiga can handle?
Thanks

Yup, you can decode MP3s to hard disk, but then you`d need around 10x the amount of disk space to store them all.
-
WildStar1063 :Is it possible to convert an MP3 to an audio format that

Yes! convert it to 21khz 8 bit IFF...........you will hardly notice the difference
I digitize my own music in an Amiga format using DSS8+ at about 19.9 khz and they take about the same amount of space as MP3's and even a plain Amiga can play them nicely...........everyone asks me what did I use to digitize this music and play it back at such good quality?
I tell them DSS8+ To listen to great quality music on the Amiga.......it doesn't have to have the .mp3 extension. Your PC owning friends wont know the difference.
And as fo everyone here who thinks Amigas cant play MP3's
Ever heard of a MAS Player? some of you need to get out more.......really! Doesnt a PC use hardware to decode MP3? well so do Amigas............ I hear yo say, no! they do it with sofware...........yes but that software is hitting the PC hardware wich is powerfull to play MP3, so we Amigans have the MASPlayer hardware! Get One! and tell this dude to ask EYETECH or someone to manufacture them and advertize them more.
-

Sure as long as you have oodles of hard drive space. One program that comes to mind (IIRC) is Forrest on Aminet. It will convert the MP3 to a WAV file which even a stock A500 could play (with the proper libs)
-

Should handle it fine, if you get a hardware decoder for it :-)
-
Remember, the Amiga is a German computer.
And that would make what difrence besides i thought commadore were american .
using a masplayer you only need a 7mhz machine .
convert the MP3 to a WAV file which even a stock A500 could play (with the proper libs)
but a 5 meg file becomes 50 meg your going to need a large hard drive on an a500 .

Individual Computers shows their Atlantis external sound card/box for any Amiga.
http://www.jschoenfeld.com/products/atlantis_e.htm
Jens' stuff is great and usually doesn't cost an arm and a leg.
I haven't seen this on any retailers site in the U.S. so I don't know if he's shipping these.
-
i have used mp3 on amiga since forever...even before mp3 :D ...mp2...eeerk :D
anyway i have been a 060 user since 1995.. and iirc it was in 96 when i first touched an mp3 on amiga, quality and playback has never had to be pressed down.
but then again its 060 ..
now with sb128...and ppc..well can't really say its better...
i want a dsp card.. :D
doommaster:can you please go to some pc board?, i am getting sick of you.

14 bit calibrated audio is just as good as 16 bit from a SoundBlaster Live sound card with the exception that you lose some upper end sound range. Majority of people would not even notice the difference.
I suspect you did not set AHI up right, and you probably did not calibrate your audio using CyberSound. Without calibration, your 14 bit audio will sound horrible as you describe.
I use Klipsch Promedia speakers on paula, and it sounds excellent, again, minus a bit of the upper range. Most people would not know.
-
I agree.
The only thing my SB128 is really good for is convenient audio input and mixing with the CD audio. If you plan on using higher bitrate audio on SB, you'll need a 68060.
Streamer2 supports the parallel-port MAS and MAS Pro as well as the Delfina, so you could even listen to Internet Radio on a modest machine. (Well, one that supports OS 3.5)
-
As a follwup to my post about Individual Computer's Atlantis external sound solution for any Amiga....I also found this:
http://www.jschoenfeld.com/products/delfina_e.htm
It seems the delfina flipper is also capable of playing mp3s and taking the load off the processor.
I could be wrong but that's how I read it.
-

The difference is not that difficult to discern
IMO...high frequency sounds are clipped and
fuzzy.
I suspect you did not set AHI up right, and you probably did not calibrate your audio using CyberSound. Without calibration, your 14 bit audio will sound horrible as you describe.
Set up right, and at 44kHz, any sort of
delicate string music or piano sounds like
crap. It's OK for beat music or classic rock,
and admittedly it's acceptable for what
it is (an old ghetto 8 bit chip).
-
I used to decode MP3s to aiff (Stephane TAVENARD`s mpega player cli-command), and then playback the aiff sample with 14bit calibrated Paula (Thomas Wenzel`s Play16) to a MiniDisk recorder. I had only a 030@25 with FPU, but I wanted to listen the songs at the maximum quality.
There are limits to S/N ratio and dynamic range, plus you may notice a noise (trashing bits?!) at the ending of a song (low volume). I used the CyberSound to calibrate the output.
Listening the recording is acceptable, but if you instantly listen the original, then the difference is great.

You could try something like this:

Atlantis, well, don't hold your breath for it. But the Delfina is out and does roughly the exact same thing.

NeRP is right. I get amazed at how many people buy a sound card without knowing that. You'd much better get a faster processor that can handle realtime MP3 decoding, cause then you'd get both speed and the sound you want.
You have to use calibrated, it makes a big difference on some systems. The procedure is a bit tedious to learn on the docs and all that, and sometimes you won't get it right at first, but you won't regret it.
You'll be amazed at what Paula can do.
Paula rocks!
-
Remember, you need at least a 060@50 to get good quality sound, anything less would mean poor quality and speed. Even an 060 you can't do anything too much. I have a PPC and 060 so i don't have this problem! :-) Use AmigaAmp!
