51The max AU size is used to pre-set max size of AU that can be written in the 3GP writer
52For audio standard with variable AU size, there could be some encoding settings leading to AU size
53exceeding this limit.
54For AAC streams for instance the average AU size is given by:
55av AU size = (av bitrate * 1024)/(sampling freq)
56If VSS returns the message:
57>> ERROR: audio AU size (XXXX) to copy larger than allocated one (YYYY) => abort
58>> PLEASE CONTACT SUPPORT TO EXTEND MAX AU SIZE IN THE PRODUCT LIBRARY
59Error is most likely to happen when mixing with audio full replacement
