Regression
Yes
onAudioFilterRead allocates memory every frame instead of reusing the same buffer
How to reproduce:
1. Open attached project
2. Open scene Untitled.unity
3. Build to iOS and run
4. Attach the Unity profiler to the device
- Observe how the Memory Used Total slowly increases (about 0.1 every 4 seconds or so) until it reaches a certain amount, then it gets Garbage Collected
- Reproduced in Version 5.3.4p1 (e89f89413a91), Version 5.4.0b13 (90500643c620) on an iPhone 5 (iOS 7.1), iPhone 6+ (iOS 9.3)
- The initial Used Total amount in 5.4b13 (~50mb) is greater than in 5.3.4 (~30mb), and the memory is also more unstable (but has a linear increase pattern)
- Not reproducible in Version 5.2.4f1 (98095704e6fe)
