Re: DSP Effects R11

This is cool, I love the ReplayGain feature... "EBU R128 LUFS level -18" is my target. But I don't understand the "Warning: Normalisation gain would have resulted in clipping, gain has been reduced to prevent this..." message. I don't want this. Can you make this "feature/correction" optional, please? Most mp3 players have a pre-amp option and also a prevent clipping option, so dBpoweramp shouldn't care about this! In fact, Foobar2000 doesn't care about this, and I'm happy with that! But I would be even happier if dBpoweramp acted similar.

Re: DSP Effects R11

Apparently clip prevention is now disabled by default in ReplayGain.

The checkbox "Disable Clip-Prevention" actually enables the clip prevention.

There are some minor changes in the logfile, I guess that is intentional:
R10: -dspeffect1="ReplayGain=-albummode={qt}0{qt} -r128 -r128lufs={qt}-23{qt}"
R11: -dspeffect1="ReplayGain= -albummode={qt}0{qt} -r128lufs={qt}-23{qt}"

Re: DSP Effects R11

Would it be possible to make Replaygain take into account Discnumber so multidisc titles are gained separately?

Re: DSP Effects R11

Now released.

Re: DSP Effects R11

@kareha - it is a tricky one, because there are certain multi disc sets where it is the same album split over different discs, and there are other box sets which are created from dissimilar albums.

New to the forum. My name's Chris, just registered today, but purchased dBpoweramp in March and have been learning and following the topics since then.

I'm a little confused about the Disable Clip-Prevention checkbox. tommybs mentioned that it's already disabled by default, but I don't see it already checked. He also mentions that the checkbox "enables" clip prevention.

So my question is, should I check or un-check "Disable Clip-Prevention" to not have dBpoweramp correct the gain?

Re: DSP Effects R11

It was a bug whilst in beta which was fixed in full release.

The replaygain dsp does not apply the gain, it writes ID Tags. If clip prevention is handled by the player, it can be unchecked.

Re: DSP Effects R11

Thanks for the reply Spoon. Wasn't sure I'd hear from anyone today, being a holiday.

If clip prevention is to be handled by the player, then wouldn't I want to "Check" the box? From what I see, checking the box prevents (disables) dBpoweramp from doing the clip prevention, making the player then responsible for handling it.

Re: DSP Effects R11

That is correct.
