I retrieved MediaInfo from AppStore to analyze some of my demuxed MXF contents. So, there are several elementary audio streams that I saved as WAV and as AES simultaneously. The WAV files are recognized as WAV:RF64 by MediaInfo. The same streams saved as AES should also be 1 channel per track and therefore AES3, but MediaInfo does only show the size of the file. Even if I rename the extension from .aes to .aes3 there is no change.
