Sorry I should have specified what I want to do.
Yes, Bishop I am looking for dialogue to use with Talk Designer.
No, I am not aware of the size of PCM files.

I think the Poser Manual is in error as it says that any wav file will work. I have been trying for ages to work out how I could get the couple I had to work. But unfortunately I doubt whether wav files that have been encoded using MP3 compression will work as these are the ones I have been trying to work with.

Thanks again
