Compressing and normalizing aren't the same thing.  I would strongly
recommend against a compression ratio that high anyway as it total
ruins the audio.

Hi!

At least to me, xineliboutput - audio - Audio compression (500%) do that.. But 
it's compressing everything..

[vdr] Anybody working on AVC (Automatic Volume Control)?

2007-08-20 Thread Harald Milz
Hi,

some commercial products (LCD TV sets, mostly) now start to offer a feature
named AVC that is meant to prevent ad blocks from being significantly louder
than the rest of the programme. While it's clear that this requires on-line
detecting advertising (as opposed to off-line processing with noad), is
anybody working on such a feature? 

The bad news is that there's no easy way of turning ad volume down when
using AC3 or PCM over SPDIF by some way... softdevice could do something
about it because it needs to demux the MPEG stream anyway.

Any idea?
