| (...) Hmmm is there a "raw data" mode for the sound sensor? Seems to me, it may be possible (maybe not yet but one day) to write a program that does FFT analysis, as long as it can get the raw wave data from the sensor. I'm assuming the "tone mode" (...)

| (...) The raw mode still just returns one number - essentially the integrated sound energy, where the weighting function is determined by the sensor mode (dB or dBA) and is all done on-board the sound sensor itself, not in the NXT. (...) You only (...) (19 years ago, 5-May-06, to lugnet.robotics)

| (...) There is a curious 6th wire connection from the sound sensor which sends analog sound to the CPU. I am assuming that using some 3rd party firmware, it might be possible to digitize and process sound data. But I think turning the CPU into a DSP (...) (19 years ago, 6-May-06, to lugnet.robotics)

| (...) I agree about high grade DSP, but frequency discrimination may be quite possible... in the past we had a product based on a puny 8MHz 80C188 that was able to run ISDN stack, transfer 64 kbits/s data on one channel, 64 kbits/s voice on the (...) (19 years ago, 6-May-06, to lugnet.robotics)
