Since the release of Dolphin 3.5 half a year ago, audio processing in Dolphin has changed a lot. In Dolphin versions up to 3.5, a lot of games required low-level emulation of the DSP code in order to not crash or get audio output. This low-level emulation (called DSP LLE) is unfortunately a lot slower than high-level emulation (DSP HLE): while low-level emulation emulates extremely accurately the DSP code by translating the binary code into x86, high-level emulation simply runs C++ code which...
