Joel de Guzman is very generous to share this intriguing Bitstream Autocorrelation concept and also an implementation in C++. That implementation is for platforms like microcontroller and DSP chip where IO samples are integers. Not sure if the bitstream approach will compare so favorably against FFT based autocorrelation within a float oriented framework like Pd on general purpose architectures.
