ReplayGain

[Servatius]

This means it would be the task of the renderer to extract the ReplayGain info from the audio stream and to adjust the loudness accordingly. The control point could tell the renderer whether to use album or track gain (at least the control point supplied by the renderer's manufacturer could do so), or the renderer could offer an option to select which gain to use.

So lets wait for renderers and control points actually doing this.

Thanks very much, Simon, for considering these things.
