In Rhythmbox it's possible to disable compression for ReplayGain by unchecking a box in the settings of its ReplayGain plugin. The option is described like the following:
It provides configuration options for [...] enabling or disabling compression in order to prevent clipping.
I wonder if there is such an option in Banshee? I have checked in its menu and glanced under Banshee in the dconf-editor without finding anything.
The reason I'm asking is after reading the following in the ReplayGain specification:
The audiophile user will not want any compression or limiting on the signal. In this case the only option is to automatically and temporarily reduce the pre-amp gain below the user-selected setting for tracks where clipping would otherwise occur.
