Fixed: With some sound card drivers, unwanted sounds were heard when audio got silent (e.g. by pausing). The modification of silent buffers, which seems to cause this issue, is now optionally available via the troubleshooting options in the Configurator.
Fixed: In the Configuration Editor the peak gain display in the analysis panel was sometimes showing incorrect values.
Improved: The GUI of the GraphicEQ command can now import the measurement text file format from Room EQ Wizard.
Added: Configuration Editor, which allows to edit configurations in a graphical user interface. Contains GUIs for most commands supported by E-APO, but as lines can also be edited directly, all commands can be used.
Added: Command "GraphicEQ", which can act as a regular, fixed-band graphic equalizer (via the GUI) but also supports variable bands so that any desired frequency response can be specified. Internally, it is implemented via convolution with a generated IR.
Added: Command "Convolution", which allows to convolve the signal with a user-provided impulse response to achieve e.g. equalization or reverberation effects.
Improved: Configurator performs checks for registry values that are needed for the operation of E-APO, which may be changed by driver installations, fixing the values if necessary.
Improved: Configurator shows which is the default device as a hint to the user.
Added: New troubleshooting options have been added to the Configurator that can be tried in case of problems.
Improved: E-APO is now normally always installed as LFX/GFX, also in Windows 8.1 and later, to avoid problems with some applications bypassing SFX/MFX APOs (e.g. Skype).
Fixed: If the input channel count was higher than the output channel count and there was no child APO, Equalizer APO could crash during initialization.
Fixed: If a file in the config path was only renamed (not modified), the configuration was not reloaded.
Fixed: Windows 8.1 is now supported.
Added: Filter types LSC and HSC that allow specifying the shelf slope with center frequency, unlike LS/HS 6/12db which use corner frequency.
