the first graphic represents compression (dynamics process), not file compression.

you are correct, my bad! I'm looking for file compression as in wav vs mp3, but I couldn't find an example clean enough like the one on top.Ideally, I want to do a simple soundwave in horizontal format, like this:
It will be animated, and it needs to show, some technical data around it to show the before and after process. It doesn't have to be scientific but it needs to be good enough for audio enthusiasts to understand the difference (which they probably know already)

Shoot me an email, i have something for you.

it's going to be difficult showing a waveform representation, other than the basic explanation of additive synthesis? ie. a sinewave represents a single frequency, noise representing all... the real problem is that rolling off frequencies over 16k wont really make much change to something easily recognizable as a audio waveform, maybe on a single oscillation - i've got a graphic somewhere to represent a smooth transition between noise and sine (to go round a rotary encoder knob for a LFO) , i'll hoke it out...

couldn't find the vector, here's a sketch of something similar - i'm not sure this is much use tbh...
additive example sort of works to show how complex sounds can be built from sine wave partials, suggests that by removing complexity (like mp3 compression) you end up with something less musical - ie. a sine wave :-s
it's an interesting idea, i'll do a bit of thinking on this tonight...

- removing partials on a additive square wave would sound the same as applying a LPF, amplifying (clip) a sine creates a squarekingsteven
- square like yr first diagram, it's just different ways of explaining the spectral domain....kingsteven

Thanks guys!
I wanted to do something using a waveform, just because animation wise will translate better for the project we are using it for, maybe that's why it was so hard for me to find examples like that...
