Hi! Thank you for your reply and I forgot to put this in the description.
The sound to be recognized is something as simple as a clap. And in theory this should be a very simple task. However, the data suggests not. Is there any reason to believe that using the "gate" function on this: SparkFun Sound Detector - SEN-12642 - SparkFun Electronics would help?
As for the arrival time, I am referring to the difference in time for the sound to reach the two microphones (placed 15cm appart). Given at a true 90 degrees, it would be zero, and at 0 or 180 degrees it would be about 440 us. Using this and a little trigonometry will give me the information i need to calculate it.
The problem is that the data I'm getting from the sound sensors is very inconsistent and must be wrong. Therefore the question is, and i can understand that it was too hidden int the last enty;
How should i get this information into a digital signal that can be read by arduino and my digital logic?
