Date: Thu, 7 Jul 2005 15:16:55 +0200 (MEST) Hi, I want to add a processing step in dsp.c, but I must say I find it difficult to fully understand how it works. A few questions and things I've noticed: * Which format are the samples in during processing? I want to multiply them with a fixed-point number - before clipping - so I need to know the exact format. * Which input sample depths are supported? The code implies 16 and 32 only, but it isn't clear from the API. * Samples seem to be scaled differently, depending on the stereo format (if scaling is needed). * When "rendering" the final samples, the scaling and clipping seems to do things that aren't needed (unless GCC is smart enough to optimize away that). Perhaps a cleanup would be in order? :) Magnus _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2005-07-07 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
