Not really, but i'm sure many people would not like to have to keep uplugging their printer just to play music, the main point is there has also been many rumours about other sound cards being done or though about, this one is actually built and working.... > What do ya mean, does it have a digital 6 channel 8bit mixer > on board?????? If yes it would mean that it is like a little > Gravis Ultrasound for the SAM.... No, it doesnt have a mixer on board, comes down to software. How it plays the 6 channels as follows: 2 channels to Front left, 2 to front right, 1 to rear left, 1 to rear right. If mixing is needed then it's down to the software. > Which is the maximum frequency supported by the card playing > al 6 channels and which is the maximum frequency the SAM > is capable to send? > (I just calculated that 6 channels 8 bit would mean 130K/second...) This all comes down to software, so far i've just been knocking up very crude code to test it with, but i've had 2 channels playing at 22KHz which sounded great! (This was with the screen off though due to bad coding :-) I guess without an sam accelerator 22Khz would be the highest. But, with the screen on, it was playing 2 channels at 15.6kHz. Although it should be possible to get it playing 4 Channels at 15.6Khz. Normally only 4 channels will be playing, most probably playing MODS, (I'm working on a Mod composer/editor at the moment), then you have 2 channels free incase any extra sound effects are required. > Very, very interesting, 'though I personally would use it only > for playback not for sampling, the quality of the 16bit 48Khz ADCs > of the GUS are unbeatable, and if I convert 16bit sound to 8bit > it still sounds much better than anythink sampled at 8 bit ... Yes, but not everyone has a PC, let alone a Gravis Ultrasound, so i feel the sampler module is nessesary, anyway, the sampler is not built in - it's an optional extra which will plug into the sound card. Plus there will be convertors supplied with the card for converting 16bit samples to 8bit, aiff to raw convertors and all that. Hope that answers the questions... Now changing the subject slightly.... > Well perhaps it would also be useful to talk about the OS Ian Spencer > is developing in Germany for his SAM-HD interface, so perhaps > Simon speeds up his work on his HD-IF and OS .... ;-))) Is this another HD interface? So far we have Si Cooke's one, and Bob's attempt. A decent HD and DOS system would be ideal for the sound card, and if the proposed Rooksoft/Entropy SIMM board that Si mentioned a while back comes along the programs that could be produced would be excellent....
