Sorry if this is a no-brainer, but I just can't seem to find much info about this.. All sources only talk about a single wave, most often a sinusoidal wave, and never mentions how the situation is like when there is a complicated sound signal with lots of stuff going on (different timbres for example.)
Please correct me if I'm wrong, but to my understanding timbre is a product of many sound waves together (if it was an instrument, a fundamental of the instrument and related overtones, etc.). So we have many sound waves at the same time, together creating a sense of timbre. What I don't get is how this is recorded by a microphone with a diaphragm that only senses *one* instantaneous frequency and amplitude, and then transmitted electronically via voltage signals that also only has *one* value for frequency and one for amplitude at a given time, how does this actually carry complicated sound signals with timbre, and not only single sine waves?
This relates to the whole chain I guess, from mic to speaker.. I have a fundamental hole in my understanding of sound waves and I'm having a hard time finding info besides the usual sine wave intro....
Would love some explanation regarding this!:-)
