HI,
we are writing an audio unit that has huge memory requirements.
To reduce memory usage we need to cut something, so we need to figure out how much we need to hack the current engine to make it work on most devices.
According to an old thread there appears to be a 360MB memory usage limit for AU:

However, in our tests we seem to be able to use over 600MB in GarageBand.
We tested on:
- iPad Pro 12.9 (4th generation) - iOS 16.3.1
- iPhone 12 Pro Max - iOS 14.4
- iPhone 12 mini - iOS 14.2
- iPad mini (5th generation) - iOS 15.4.1
Have memory limits been eliminated in recent versions of iOS?
Is it a limit that varies according to the device?
Are there any official numbers we can rely on?
Thank you,
Ale
