Subject: Mixer volume/decibel mapping
Date: Wed, 19 May 2010 18:34:57 +0200	[thread overview]
Message-ID: <201005191834.57919.vand2@gmx.de> (raw)


Hello everyone

I'm working on an ALSA-Mixer application for C++/Qt4 and stumbled over
volume and decibel mapping for sliders.
My question: Is there always an 1 to 1 mapping from volume to decibel and vice 
versa or can there be decibel values in between two volume steps?

Regards,
Sebastian H.
