but don't you also want to be able to sell as many copies as possible to as many satisfied customers as possible? if so, you have to pay attention to whatever standards can be found for the domain at hand. in this case, the AC97 codec spec (and its recent successor whose name i forget) is about the most relevant thing i can think of. AFAIK, AC97 etc. say nothing about the kinds of gain control and mix routing that exist for multiple PCM streams. ergo, there is no standard way to do this that will work across a significant fraction of the installed and/or potential user base. so, either ALSA can come up with such a thing, which might be interesting but the manpower available to work on it is very limited, or parties that have a vested interest in it can use an existing API (SDL springs to mind, though i've never looked at it) or develop a new one that provides a standard mechanism for doing wat you want. i mean, even at the most basic level, the audio interface that is built into my laptop motherboard (some intel nonsense) cannot do any sample rate other than 48kHz! this is a high end laptop (HP Pavilion zd7000, 3GHz processor, 1440x900 display, etc) ... think of the cycles that will be spent *resampling* your audio independently of the mixing step. this type of BS seems to be growing more and more common. if i was in your position (specifically, if i have to assume that my user base spent a (comparatively) lot of money on a graphics card, maybe even paid for a 5.1 speaker setup, but are still using the factory-provided audio interface, i would assume the absolute worst capabilities for that interface that i could: single sample rate, single PCM stream, no mixer. and btw, i wasn't suggesting that you just "sit there waiting". my point was that the time you might spend working on this could be spent working on something else, and by the time you're done, CPU speed increases will have done this particular task for you. --p ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
