* amadeus: Allow OOB read of GC-ADPCM coefficients Fixes "Ninja Gaiden Sigma 2" and possibly "NINJA GAIDEN 3: Razor's Edge" * amadeus: Fix wrong variable usage in delay effect We should transform the delay line values, not the input. * amadeus: Update GroupedBiquadFilterCommand documentation * amadeus: Simplify PoolMapper alignment checks * amadeus: Update Surround delay effect matrix to REV11 * amadeus: Add drop parameter support and use 32 bits integers for estimate time Also implement accurate ExecuteAudioRendererRendering stub. * Address gdkchan's comments * Address gdkchan's other comments * Address gdkchan's comment
