If your doing Real Time Audio Processing, there is a group dedicated to doing just that and have produced a bunch of tools in an open source package for working on it. It's called "Jack", http://jackaudio.org/ Note that the consensus of the Jack Community[which includes professionals in audio development] is that the Real Time Kernel options aren't needed for most use cases. http://jackaudio.org/realtime_vs_realtime_kernel *"No. Realtime scheduling is available on all Linux systems no matter what kernel they use, and current versions of JACK use it by default. A kernel built with the realtime patches (an "RT kernel") is needed only if:* - *You want to run JACK with very low latency settings that require realtime performance that can only be achieved with an RT kernel* - *Your hardware configuration triggers poor latency behaviour which might be improved with an RT kernel* *Most users do not need an RT kernel in order to use JACK, and most will be happy using settings that are effective without an RT kernel."* Personally, I'm such an extremely lazy programmer that I'd START with implementing my application using Jack and a reasonably sized tempfs drive to store files while working - and then ask my performance tuning questions on their mailing list as 80% of the issues won't be related to the hardware. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
