Visual Representation of Sound

Hi There — I want to create a spectrogram that visually represents all the qualities of a sound, something that can actually regenerate the sound. Right now I am using the built in spectrogram but it isn’t quite doing the trick. It only shows the amplitude and phase and not even at the same time. I want to see the frequency, timbre, pitch etc. Does anyone have any idea how to build something like this?

timbre is actually the spectral footprint over a certain amount of time, hence, what you’re after is merely pitch+time, and thats what spectrogram is about.
Load up “spectroscope” and switch it to spectrogram mode.
You cannot use it for resynthesis though, you will need to look into pfft~ for that.

nice timbre definition.. been meaning to put my finger on that, thanks.

I mistyped, its actually sonogram mode. But he’s not following this thread anyway :))
