Hello, I am in search of a program that allows a user to create a line graph plotting wave frequency (pitch) over time. I would then need the program to play back the sounds that have been constructed graphically. Is pd capable of this? Can someone point me in the right direction?

Any help would be greatly appreciated.
Thanks

I love you. Know if a manual is available anywhere? In the screenshot on the homepage, it looks like there are individual frequency/time points that are connected. I have not been able to figure out how to achieve this, but so far it's fantastic and just what I was looking for.

Thanks so much!

In the Pd Documentation Browser:

4.data.structures/14.partialtracer.pd

Pulsed, I'm not sure exactly where to find what you're pointing to. Is it a patch of some kind? Any other recommendations for software that can precisely plot frequency over time? Parameters I need control over are starting frequency, ending frequency, length, and shape of line that connects one frequency to another (straight line, exponential, etc.). Also, logarithmic herz distribution (or even MIDI frequency) would be great, too. Is PD capable of this? The documentation cites one visual score as plotting frequency on the y axis, time on the x axis, but then explains that "this behavior isn't built into PD." I really don't understand how to achieve such a graphical situation.

Any help would be greatly appreciated.
Thanks!

In Pd-extended its in main window->Help->Browser->Pure data->
