[DCP-o-matic] audio samplerate/frame rate reference

I am bringing this up on the list as I may not have understood the issue completely myself, feel free to comment... I rarely do split video/audio projects, so never came across the issue myself doing real work, but I remember we talked about it from time to time already. Consider the following situation: Someone wants to create a DCP from content created at 25fps, he creates either a video or image sequence with 25fps, and a split audio file with that timing reference as well. Now, in DCP-o-matic he want's to create a 24fps version. It is not a problem to instruct DOM to recalculate the video frame rate, stretching the video in absolute length. But what about the audio timing reference if I do NOT want to process the audio file externally to 24fps? I should be able to tell DCP-o-matic 'use this audio, but resample to a 24fps reference'. Actually I though that was possible using the frame rate input box under 'Content'->'Audio' - but it seems this is not possible. I can input '24' there instead of '25' (as I would with the video), but nothing changes about the audio sample rate? - Carsten
