10.6 Audio Waveforms Take Forever to Load

Reading this thread I feel less alone. I have had every audio issue with my project. 2.7 hour file. Trying to chop it into bits but it's really hard when you can't hear the cut points! First the audio wasn't transcoding properly except in Quicktime, tried an MOV, still was SUPER choppy to the point of unusable. Made a compound file with an M4a which means I can now HEAR the audio but I still can't see the waveforms. Like everyone else it takes forever for a screen's worth of them to load, and once I move through that bit of the timeline, I have to wait a good 5-10 min for the next chunk to show up. SOMETIMES I can get it to go faster if I pause and play again. But not always. I've tried rendering in the background and not. This whole thing has eaten a week of my and my client's life. The whole project should have been a day. What. The. Heck.

Good news: the waveform generation issue is fixed in 10.6.2, which is now available.

Can confirm! 

I am using an early 2015 base MacBook Pro 13" and even on a 4K timeline with the media in an external USB drive, I can now cut with waveforms loading nearly instantly.

I feel like I have a new Apple Silicon device again 🤩
