Ever since I installed Mojave (10.14.3 in a Mac Pro with SSD NVMe drive), while recording, both in Waveform and in Multitrack, Audition can spontaneously stop recording with no warning.
I do voice overs, and I had resorted to placing the undocked "Time" window in the booth screen, to make sure it was recording. But it turns out that THAT wasn't a guarantee either. The "Time" window would continue running, but the program had stopped recording! You have to see it to believe it. I'll try to make a video of it next time it happens.
I've had to resort to pushing the Audition window into my booth screen so I can compare both "time" clocks.

Also, as mentioned by others here, many times when I stop recording in Waveform, and then start again, everything goes haywire: the new audio is out of synch (or absent) with the display. If I hit "Undo", anything can happen. Frequently, instead of actually undoing the recording, it will randomly paste another bit of audio.
It can also add a bit of another completely different previous recording at the end...

Any help would be gratefully received!
