Is there another solution for this app?
•I have characterized my target sounds in three frequencial components (Hz), with their amplitude (dB). And I only want to compare the sound measured with these components but I can't split them from audio samples I have taken.
Grumpy_Mike: I could compare with a template, but for example, I don't know if it will work when volume doesn't be the same.
So if it is a truck, it will be a specific truck in one determined moment. If it is a trumpet, it will be the same trumpet playing the same music notes.I had thought about make a first reading amplitude attempt (in dB) for three different frequencies, then save them, and after that listen sound compare with them for detect if is positive/false detection.
