I have this audio analyzer app that fills a buffer with audiorecord, runs it thru a bunch of filters, and plots the filter out as a bunch of vertical bars. I timed the sampling, filtering and drawing with systemTimeMillis and it takes about 100ms,900ms and 50ms. I cant see how putting the calcs in another thread could speed it up any, but I'm just an old embedded c programmer. I guess linux is ticking every millisecond, and there must be a dozen linux tasks running, and I guess a task has a 'quantum' of ticks that it runs before linux preempts it (anyone know about these details?), but I just want it to run about 5 or 10 times faster. Appreciate any hints, tips, tricks, etc.
