Thanks for your response.
That makes sense that a wav file does not have a frame rate, however, when the file is converted to DCP format an mxf file is created with the mono wav files and that does seem to have a frame count that corresponds with the frames of the picture.
Could it be that my frame count (length) is getting off in conversion? Should there be any difference at all in length between a 32bit wav and a 24bit wav?
Is there any way to do what you have described without Audition?
