Application doesn't work with this type of infile

[unfunfionn]

Probably a really stupid question, but I can't find an answer elsewhere.

On Mac and PC, 60% of the WAV files I'm trying to run through any of the Distort, Blur etc. functions are just returning 'Application doesn't work with this type of infile'. But doing a simple paplay with the file is no problem.

Can somebody point me in the right direction?

Okay, the files weren't mono and those functions don't work with stereo.

But why? And is there a way to extract a single channel from a stereo file and work purely with that, or does it need to be done outside CDP first?

Interleaving mono files to make a multichannel file is a very common operation in CDP, and is supported by "submix interleave"
and "interlx".  Similarly, splitting a multichannel file into N mono files is done using either "housekeep chans" or "channelx".  On the PC, Soundshaper automates these steps in many cases, and possibly Soundloom too (or a patch can be written to do so).

Many of the processes in CDP are inherently mono - e.g. in the distort programs, it is unlikely that zero crossings will coincide across multiple channels. the error message "Application doesn't work..." almost always applies to such situations - except where indeed the wrong type of file is presented!
