Audition (Beta)

Running Audition 13.07 and an issue (previously reported here) with saved files become "offline" and need to re -associate files before closing session.  Post said to use the Beta version of Audition which had solved that problem.  It did solve that problem but now the Beta version freezes and crashes frequently and I am losing edits in the sessions.  I report on the crashes but working like this is untennable with the amount of work I have to do.  Any help is appreciated.  **and BTW I am operating an older iMac with iOs High Sierra 10.13.6

When I use the "Stretch and Pitch" process, and have "Lock stretch and pitch shift (re-sample)" selected, AND "Constant Vowels" selected, I get horrible distortion in the file once it's processed. I'm using the Audition algorithm on the "High" precision setting. If I uncheck "constant vowels", the file will process normally without any audio distortion.

As I edit a podcast using this build, I have to use a buffer size of 1024 to avoid dropped samples. Previous builds would work with no problem at 512 on the same project. It's a 4 track project with predominantly built-in effects processes, and a few iZotope RX plug-ins (Voice De-noise and De-Ess) running as AU. Computer is a 2018 MacBook Pro i9 w/ 32GB RAM, 1TB SSD, 10.14.6, and a Universal Audio Arrow Thunderbolt interface.

If I use the new Replace Media function on a file that is not used in the sequence the file is removed from the Files Panel if I just cancel the dialog without relinking to another file. 

Audition (Beta) now supports relinking source media in the Files panel, and displays missing files as "offline" files in the Files panel.  Updated context menu commands make clearer how selected clip(s) will be relinked.  

Any ETA? I'd love to use Au as a creation tool!

Audition (Beta) now supports automatic switching of default input and output devices when changes are detected to the default Mac OS settings.  By default, Audition now uses "System Default" as the Input and Output Device options in the Audio Hardware preferences.  Now, when plugging in headphones, a USB microphone, or connecting bluetooth listening devices that MacOS uses as the new default, Audition will automatically switch to use these devices for playback and recording as well.   Certain devices, such as Apple Airpods, have limited sample rates for their microphones which can cause playback degradation.  In this situation, Audition will change the default audio output device, but disable the input device, to ensure full fidelity.  Users can override this behavior by selecting the limited input device manually, as before.
