/*
* DMOPlugin.h
* -----------
* Purpose: DirectX Media Object plugin handling / processing.
* Notes : Some default plugins only have the same output characteristics in the floating point code path (compared to integer PCM)
* if we feed them input in the range [-32768, +32768] rather than the more usual [-1, +1].
* Hence, OpenMPT uses this range for both the floating-point and integer path.
* Authors: OpenMPT Devs
* The OpenMPT source code is released under the BSD license. Read LICENSE for more details.
