How do you mean, compromise?
I think the SCSI interface is the only option we have, and by using D2D, the computer is free to do anything else, while the music plays...
Hm, it seems like Motorola donīt make pure MPEG chips, they use their powerful DSPīs to do it. I stole this from Mot.com:
"For portable application such as MP3 decoding, the Motorola Symphony Onyx DSP family needs ~22 MIPS for MP3 decoding. Motorola was able to accomplish this low MIPS usage because the Motorola Symphony DSPs were designed as 24-bit processors that are ideally suited for processing audio. This means that the MP3 decoder would use ~13.2 mW and ~8.8 mW at 1.8V and 1.5V respectively. At the same time, systems could be designed that then clock the DSP at higher rates to provide for features such as MP3 encoding on the same portable platform."
They use the DSP in the SOUNDTAINER, how about this:
"SOUNTAINER, which will be available in the second half of 2000, is initially offered with MP3 encoding and playback technology, but future versions may be upgraded with virtually any available future audio technology including MP4/AAC, 3D-sound-virtualization, sound-equalization, SDMI compliant software and other formats. DIALOG4 is working on a powerful software library for different applications to fulfill the demands of today's and tomorrow's mobile community. For the consumer, SOUNTAINER can perform many different uses, such as: A stereo recorder to convert CD's in realtime to MP3 files without PC (LINE input is available), a stereo "live" recorder (stereo MIC input is available), a dictaphone with USB network access, a MP3 player, a sound-processor to transform stereo signals to virtual 3D-sound for action games and an external audio device for the hifi-system, just to name a few."
Now, a DSP wonīt only do MP3īs, it could also be used to do lotsa other things... But then I suppose weīd have to put it inside the computer. OR maybe the data to be processed, could be sent out via the SCSI, to the DSP, and then in again... Would be the simplest solution, or??? Very flexible, anyway. We wonīt even have to open up the computer at all. ;-) And such a device would increase the processing power of the ST, beyond...
Anyway, We need some very good coders, are there any still around, on the TOS scene??
-Else, what??
