Really Love your explanation Kosma and thank you for the interest, it seems you’ve been studying a lot and I appreciate you taking the time on writing.

From my point of view, and I’m not a very illustrated individual on this, neither dequalifying my opinion, Frequency is the repetition of any action over time, so when it comes to audio frequencies, a frequency is how fast a field oscillates producing an audio signal that can be percieved by a subject like a human or animal.

I might not be right haha so let me know. 🙂
