Does anyone know or use an Audio Controller/Manager?

I'm not sure what this type of software would commonly be named under but I thought Audio (Sound) Controller-Manager would be close. The problem is that the 'volume control' program defaulted on windows xp is not sufficient - it doesn't provide any detail information, such as the Hz or kHz that the "volume" was set to. It doesn't have any numbers and I need numbers.

Someone who does music-related activities would know a freeware for this kind of program.
