Demo:

I have to ask, what did you use to make this with almost an hour's worth of audio? Any time I use this: with audio over 50 minutes just conks out after a while

i also use the same colab but for me stuff like 1h and 20 of audio works with no problems

How do you prevent it from disconnecting or crashing, like for the longer processing times for epochs?

it just works

i dont have to anything

Local install, I have a 3060 so I don't need to worry about disconnecting

I use the same he does. I dont have to worry about disconnecting. Try to move your mouse / cursor everynow and again to stop afk disconnection.
