iphone Programming Glossary: bandhttp://stackoverflow.com/questions/11173605/detecting-a-clap-in-ios you'd be better of doing a spectral analysis FFT of the input signal and then looking in a much narrower frequency band for a sharp signal spike similar to the part you already have. I haven't looked closely at this source but here's some possible..

Generating DSP filter coefficients in C/Java for time-domain convolution http://stackoverflow.com/questions/8014018/generating-dsp-filter-coefficients-in-c-java-for-time-domain-convolution I've also taken one undergraduate EE class in DSP and know how to use Matlab. I would like to apply low pass and band pass filters to my time domain signal. From my understanding I need to perform convolution of my time domain samples and.. the filter coefficients . I know that for the low pass filter the coefficients come from a sinc function and the bandpass filter is basically a shifted low pass filter. How can I programmatically generate these coefficients java android..
