I have two identical-length wav files that I would like to use as a modulator and carrier, respectively, and produce an output file. Is there a simple way to do this? TIA!

Hey hey,
there are a few ways. there are a few UDOs with vocoders. I know that Victor has written one or two and I have as well:
http://juliencoder.de/sound/m_vc110-1.2.zip
These are classic virtual analogue vocoders. Also using the PVS opcodes you can use pvscross. Going by the settings suggested in the manual (1024 FFT and window size, 256 samples overlap) I get 1.5 * 1024 samples delay with PVS.
HTH.
Best wishes,
Jeanette
P.S.,sorry, I just remembered that I also encapslulated the pvscross opcode in a UDO as well:

It sounds magnificent! Thank you so much!!
