What software do you use for creating those nice DSP diagrams?

I normally use a bitmap editor to scratch them out, and the results are less than perfect. Years ago I used graph paper, today I'll use MS Paint if nothing else is at hand.

CAD with symbols, drawing software ? Is there anything available that already has common DSP symbols ready to use? (mixer, oscillator, filters, Greek alphabet, delay lines etc)

I do primarily audio and LF/HF RF work with real and quadrature signals and want to be able to present nice-looking diagrams to both technical and non-technical people.

I have schematic entry systems for EE and modelers for the mechanicals, but my diagrams really do need help.

Thanks!
