XMA 2.0 Block Size
XMA 2.0 defines a parameter, the "block size", which is used to create a seek table. The seek table contains the number of samples in each block, so it is useful for seeking in XMA data more efficient...
- XMAHAL: XMA packets need to be 2K aligned
...ine loads bank is created using AK::PhysicalAllocHook(). So does the default Stream Manager on Xbox 360. 1) Ensure your implementation of AK::PhysicalAllocHook() uses XPhysicalAlloc, with the ulAlig...
- Using XMA with Interactive Music
The XMA encoder produces 384 "blank" samples at the beginning of sounds. And due to the encoder's FFT windowing process, there is also a fade-in over about 128 samples, half of which are located at th...

...tform initialization, using AkPlatformInitSettings::threadLEngine. We are not multi-threaded on Xbox360.
- CPU spike when starting a streamed sound (Xbox 360)
On the Xbox360 HDD, ::CreateFile() sometimes takes a lot of time to execute (a few milliseconds!), as if the HDD went into some sleep mode after a few seconds (~15) of inactivity. Since AK::Stream...
- Audio frame size on the Xbox 360
On the Xbox 360, the audio frame size is 1024 samples at 48 KHz, which corresponds to about 21.3 milliseconds.
- Do I really need to call ::XPhysicalAlloc() in my implementation of AK::PhysicalAllocHook()?
... use XMA sounds in your game, YES, you do!
XMA data is decoded by a hardware decoder on the Xbox 360, which requires that data be allocated by ::XPhysicalAlloc(). Every time the sound engine alloca...
