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.
