Wann erscheint die Audition Version für den neuen Windows ARM Snapdragon Elite?

Who said that a new version of Audition was to be released? Where?

The considered view from the rest of the world is that if you run an ARM x64 emulation, by and large you will get the 'native' performance anyway from Snapdragon. So you can just run the version you've got and get any benefit there is (if there is any) anyway. This applies particularly to non-video apps like Audition. With Adobe's more visual-based ones the situation may be different - which is why they've already released some.
