I am trying to implement a method which should be called each 10ms with a precision not less than 0.1ms (better 0.05ms). This method is very complex and it is generating sound samples which are placed to float[] buffer to be played with OnAudioFilterRead function.

I have tried both Coroutines and InvokeRepeating - both are bad, because they can call the method with period from 7ms to 13ms which is not acceptable.

The only idea I have is another Task with while() cycle checking the Time.realtimeSinceStartup permanently. But I feel like this is a bad idea.

Can you help me? Thanks.

Yes, You can use multi-threading which is not recommended in many cases but it can be used if threads are managed correctly and made sure that Unity API is being called from main thread only.

Why Should I Use Threads Instead Of Coroutines?

Hope this helps :)
