If that is the case, you need to tell us what is unique about the sound of the frog that be isolated from other sounds.Thanks to you all,
I want to create a project that can only detect the sound of a frog that can output to a servo motor. If the sound detected is not a frog voice the circuit does not operate.
No , you can't use frequency - magnitude plot only. Timing is very important as well. What you need is frequency-time-magnitude, they called it's waterfall spectrogram.I uploaded some spectrum graph. Can you tell me what type of approach and design that I need to do.
Sorry everyone if i cannot explain it more clearly and specific. That's why I'm here to seek help!. thank you all
