Added: Filter type "IIR", which allows to specify a user-defined IIR filter of arbitrary order with custom coefficients. Improved: For playback devices, the APO is now installed both as GFX (post-mix) and LFX (pre-mix) APO. Normally the filtering happens in GFX, but the command "Stage" allows to select LFX to apply effects based on the number of input channels. Added: Expression language. The commands "If", "ElseIf", "Else", "EndIf", "Eval" and inline expressions allow to change the filter behaviour based on runtime conditions. Added: Command "Copy", which copies audio data between channels. Added: Command "Delay", which delays the audio on the currently selected channels. Improved: Configuration files are now locked exclusively for writing while reading them. Improved: There is now a transition (10 ms) from old to new configuration after loading. Improved: Substantial internal restructuring to improve extensibility and maintainability. Filtering commands now work exactly in the order they were specified. Fixed: When the microphone input was in stereo but the application requested a mono stream, the audio was heavily distorted. Fixed: The sine sweep generated by the Benchmark application had floating-point precision issues leading to severe artifacts when certain filters were applied.
