Thought the AD516 Sound Card was useless, NOT!!! Chris Brenner has written a Driver and reverse engineered it, so now all Amiga users can use it with AHI.
Th Sunrize's AD516 has been one of the most interesting ZII audio boards. Unfortunately, until now, there weren't any drivers of any kind for this card, leaving owners in need for realtime software with the only option to use Studio16, the application developed for this hardware by Sunrize and bundled with the product.
Lack of detailed documetation, and the fact that Sunrize left the market, prevented from taking advantage from more modern non-linear editing software, developed years after Studio16. Until now.
Chris Brenner just relesed his new excellent AHI driver, avalable on aminet, that now allows AHI-compatible applications to access the AD516 A/D D/A converters (for SMPTE support, Studio16 is still the right tool). Several applications have been already tested and work fine.
Early reports about ProStationAudio and this new development say that the driver exhibits low-latency, extremely important to allow using mixing automation and the 30+ realtime DSP effects for ProStationAudio. More info soon, as they arrive.
To donwload the driver, search for "AD516" on aminet. Info about the developer are into the driver archive, don't forget to send him feedback.

AD516 AHI Driver For Amiga, YES ITS TRUE!! : Comment 4 of 43 | ANN.lu |
Posted by Ole-Egil Hvitmyren on 28-Apr-2002 11:29 GMT | In reply to Comment 3 (Anonymous): Well, I think Shawn the bloody stupid bus arch troll in fact misunderstood the usage of the word realtime here. In this case it is only a matter of stuffing your data from the application to the card and getting results back immediatly, as compared to setting up everything and doing a sound "render" using the slower cpu. But PCI could have been better for real-time systems. I haven't analyzed zorro and real-time, but I actually don't think it performs any better. The thing about busses and how they perform in real-time systems is all about whether the bus and the arbitration algoritm is deterministic, so you can set up a set of applications beforehand that you _know_ will run without hickups. Any interrupt is by definition stochastic, not deterministic, so any systems with external components that can give interrupts and behave strangely with respect to bus arbitration (is it my turn to speak now? is it? now then? how long will it be then? etc) will mess up determinism. But I don't see how zorro can be any better than pci on this. Brute force actually _does_ help a bit ;) |
