New A-EON Music Card for Classic Amigas

[amigakit]

Wow!  That its really amazing that a 68000 can handle the FLAC file with Prisma decoding.

I doubt it is a full digital path for SPDIF, as the chip seems to provide only analog outputs. Unless you are doing something wicked with that built-in XilinX.

The decoder provides digital output as I2S data stream at different rates.

On the hardware side, you could offer something interesting with the 12 GPIO pins the DSP chip has. Maybe an expansion module that could provide a sort of Geekport or a simple series of relais for controlling fun stuff, or even a LCD module that could display some playback parameters.

Well, need to get some pics, but the second revision hardware has digital I/Os and also some mysterious addon module in first prototype revision It might have to do something with SPDIF output...

Stay tuned. Development is ongoing, but a bit slow due to heavy NMIs from my little daughter

This is an internal media player for amiga. Not a full sound card

To my mind this is a sound card built-in DSP like Delfina, Delfina only had separately DSP and had to programmed DSP to decode adpcm4, mp3.

For example, on the basis of sources PS3M/DigiBooster2 player can make a new player, instead of sending audio PCM to the Paula sent to the card in PCM WAV.

This is true.

However, as it is a sound card that supports WAV (i.e. uncompressed audio), we're planning to make a simple AHI driver too. It won't be a full RTA solution like a Prelude - it's not meant to be - but we're aiming to use the WAV functionality to give Classic Amigas a CD-Quality AHI channel.
It's primary focus is indeed for decoding of compressed audio, though, yes.

Then I stand corrected

Interesting. Lets see what comes out in the end.

And kids, are definately NMIs !

damn that's what I was hoping for....a new sound card, fully supported so i wouldn't have to replace my audio caps (just remove them to avoid acid damage to my 1d4)

That's what Cartoon Network is for

For one thing it'd have to be a pretty special sound card to emulate Paula in games.

Secondly, I'd very strongly recommend getting your A1200 recapped if it ever plays up at all. The sound caps do go easily... but so do some of the power ones...

Latest News updated on Prisma Megamix:

Prisma.library is completed

MHI development is also completed and working- this is good for compatibility with programs such as AmigaAmp.

A new redesign of the board and SPDIF out option has been added and tested!

We are going to production shortly with first batch being a few hundred units.

Price is of course subject to change, but to give you an idea, it is likely to be approximately GBP £70 / 85 EUR including VAT (US $ 95 ) depending on final price of the sound chip and costs of hiring the production machines.  

5 EUR more was added to cost for gold plating on the Zorro connector - we thought this would be better than going for budget options.

Excellent news.

Is the AHI driver going to be ready at launch?

[amigakit]

I will have to consult with spirantho who is currently looking into the driver's possibilities.

[guest7146]

The price hasn't been decided yet, but it won't be ridiculous. Unlikely to be £50, though, I'm afraid

This is a sorely needed peripheral for classic Amiga computers.  I will definitely purchase at least one.

I for one understand that this will not be a "cheap as chips" product.  You have to pay a licence fee for compression encode, and the way that gets handled is in the cost of the encoder chip.  They are not particularly cheap for this reason, and they are far more expensive in low numbers than in bulk.

Thanks.

It would be great to have both MHI and AHI support with a pass-through for Paula.

[amigakit]

The hardware passes through Paula sounds with a RCA connector where you can route the Paula sounds in and Prisma will hardware mix it.

@amigakit

I would buy this card but that could also connect it to a USB port for Efika and Mac mini.

Sound by AHI is a poor sound quality.
