What an amazing video that explains so much in such short time, I guess spending a year at ASR helps a lot on just understanding what it all means.
At about 20 minutes Dan Clark mention FFT and shows what a specific instrument note looks like, the importance of the fundamental and harmonics are in allowing to identify what the instrument is and how it is played, then also explain how even a small amount of THD modify both how the instrument sound and how we perceive it is played.
That explains so much, Thank you
@Dan Clark for sharing the knowledge.
@amirm when you show THD in a review, like this one (just for an example)
Can we have an idea from this how a specific instrument will sound and we will perceived it is played.
