Here are three tools to complement soundforge XP for a class I'm teaching at
the moment.  Soundforge is great but you really need a ring modulator, a
bandpass filter, and a phase vocoder.

These patches work only for mono soundfiles in "wav" format, i.e.,
little-endian as on PCs.  They therefore won't work with AIFF files (such as
the Pd distribution soundfiles!) unless you change the guts of the patches. To
convert for reading AIFF, Just change the letter "l" to a "b" in the "read16"
message in the "guts" subpatches and bash the header size appropriately.

In any case, the output files will be in wav format.
