I'm attempting to add some handling for crash recovery of a wav file that was being written to using the WavAudioFormatWriter. I believe the file will have a correct header minus the actual data length. So I'm looking for the ability to open a wav file and read in the *actual* data length and update the header. I've been looking through the code and have done some forum seaches but haven't been able to to locate anything. It doesn't appear to be very complicated but it would be nice to use something tied to the WavAudioFormatReader/Writer. Does anyone know if I missing something, or will have to roll my own?
