PGraphics limitation in array size help?

I want to convert audio samples to something like a barcode.
So I need a very wide image array, like 64000 pixels wide would be a good.
Instead I get the Exeption: Image width and height cannot be larger than 8192 with this graphics card.
I don't want to show the pixels array onscreen. I just want to create it and save it to a png or jpg. Later edit in Photoshop or something. So the graphics card i'm using is irrelevant and so is this 8192 limit.
Anyone knows how to create a PGraphics array of ANY size without limitations and draw in it?
Then save it to a file without even showing it on screen.
This is the sketch i try to run:

This is what i've been forced to do: a "page" of little strips that later I have to align in one row using Photoshop, tedious work.
The sound "page" code:

Thanks for any help in advance :)
