How do I simulate a sound that is not a point sound source?

- Stream Manager Device Memory
Audiokinetic's default stream manager creates a memory pool to perform I/O for each device (created using AK::CreateDevice()). These pools appear in the Wwise profiler under the name "Stream I/O". The...

- On the PC Platform, does Wwise cache commonly used decompressed Vorbis into memory, or does it retain the compressed files and decompress on the fly?
No, we do not cache any decompressed Vorbis data into memory. All Vorbis decompression is done on the fly.
- If AK::SoundEngine::LoadBank can load a bank from memory, will it load and copy to an internal heap, or will it use the bank "inplace" and if so will it modify the memory ?
The LoadBank() that loads from memory does it by reading data in-place, without modifying it. Audio Data is registered in-place and not copied or moved. Meta Data is parsed and related objects are ...
