Why is the specified audio format for Ibooks unsupported? ( “use AAC (8 to 320 Kbps, 48 kHz stereo) with an .m4a file extension.” https://support.apple.com/en-us/HT204433 ).
In the past, Hype has suggested using mp3, which is not part of the spec.
Our management will not allow us to submit out-of-spec products to the Apple store. I know you wouldn’t.
In addition, audio needs to play from the timeline without the need to export every time just to preview audio.
Audio needs it’s own section of the timeline, the way video editing software has been doing it for 20 years now.
