Thanks for sending the links to those files.
I find I can import both of them, but see the different behaviors. Audition appears to import both files through the ImporterMPEG plugin by default, which I believe may feed through a third party codec library. On MacOS we can utilize Apple's native codecs, but Windows requires a third-party implementation to open these files.
With the "iHeart Broadway" file, it opened as a mono 44.1K file and playback sounded half-speed. I was able to quickly compensate by selecting Edit > Interpret Sample Rate and choosing 88,200. On MacOS, when I force it to import through the native "Apple Audio Toolbox" option in the Open File dialog, it is imported as a stereo file at the correct speed. My hunch is the channel data is interleaved and the default "ImporterMPEG", which I believe utilizes third party codecs by MainConcept, is being interpreted as a single channel which explains why it's half-speed and one channel. The "Magic at the Musicals" opened as a stereo file and played back at the correct rate, but was highly overdriven and clipped. I was able to bring the levels down, though because the source wasn't 24/32-bits, the clipped samples are flattened rather than being restored. When I forced this import through the Apple codecs, it opened fine again, but reducing amplitude did restore the waveform fully.
You can see in the screenshot, the files have some different characteristics. The first is MPEG-4 HE AAC vs, but the second is standard AAC. I'll ask the team to investigate how Windows support for these files differs from Apple's codecs.
edit: I don't know why the forum won't embed the image. I've attached it as well, but it isn't showing up for me at the moment.
