There is a Soundfile class in the CsoundAC Python extension module. It's trivial to code a single cycle sine wave in Python and write it to a soundfile using the Soundfile class.

You could do the same thing in Csound itself by simply having a score that consists of one note that is one sine cycle long.

Mike
