[MPlayer-users] Dolby Digital (DTS?) 10 dB Boost for LFE channel

Hello, 

The Dolby standard requires the LFE channel to have a 10 dB boost when played back. For example, Wikipedia says:

> The LFE channel is conventionally played back 10 dB louder 
> than the main channels, giving significantly more recording headroom.

Does mplayer (or a52dec?) apply this boost? Would it even be possible; won't it clip the signal?

Regards,

Wiebe
