Request to Frank: Please take into account replaygain with other formats as well by putting the 0dB headroom possibility back to the WinAmp-plugin. It never hurts to have more flexibility.

Thanks.

Sorry to pick a nit, but the links above for the Win32 h version binaries apparently point to files labeled g version. There are "real" h version links on Frank's page.

Ooops Corrected. Thanks.

Publish a piece of music which profits from K-0 (note that the
zero "0" is arbitrary, it is like 0 dBu). The worst I found was a
K-2.... which really sound horrible distored.

I still don't understand why 0dB headroom makes everything so bad sounding?
My understanding is that replaygain calculates the scale value so that perceived volume is average 89dB SPL. This means more often that tracks will be played already quieter and a player reads the scale value and scales the output accordingly.

One purpose of title based replaygain is that all tracks are very close to same volume. If with MPC you use the recommended K-14, it will sound very quiet. All MP3s processed with MP3gain sound much louder, this is also of course a necessity if you have a portable player.

Are you saying that all tracks processed with default Mp3gain and VorbisGain adjustments and played using replaygain sound very bad?

What do you suggest for solution for multi-format replaygain situation?

Rather blunt reply Frank!

With your latest Winamp plugins the playback level compared to a standard mp3 file is as follows:

MPC file -
replaygain: say -6 dB;
haedroom amp in 0.92h: -14 dB;
TOTAL: -20 dB

That is, if I play an MPC file processed as above, and then a standard mp3 file, the mp3 file will be 20 dB louder.

Now, I know all the technical reasons why you are making this level adjustment possible, and very beneficiial they are to. However, if you continue with the lack of adjustability that the new plugins have with respect to output level, I will be forced to use an older plugin, or maybe even drop the format.

I'm a bit confused as to why you say that a 0 dB settiing in headroom is only suitable for square waves. I can play an mp3 file without any replaygain and without any headroom adjustment on my computer without any serious distortion - and it can be played at a loud level if needed.

With your new plugin and replyagain on, I cannot get a suitably loud output frm my soundcard at all.

And further, If replaygain is applied to an MPC file, lets say it cuts 6 dB off the level, and I was to play that on your latest plugins, I would still be 8 dB below original level of wave files at standard Winamp output level.

I have already uploaded ICL compiles of versions .h of Decoder and Plugin to my page.

To JohnV: keep in mind that replaygain is not about peak value (although you can use it's calculation for clip protection as well). So you would need some headroom above the "perceived average loud value" that replaygain set the volume to for the peaks that are above this.

I guess it all boils down to what you call 0, either max. digital (maxclip) or the replaygain reference value (83dB SPL on calibrated setup).

I suppose that you mean here the "crest" of the music material, the difference between average and peak levels?
I honestly think introducing those K-xx values just confuse things in the plug-in. If a mastering or recording engineer would use a K-20 meter that would mean that 0 dB would be placed at 20 dB below maxclip (and an averaging algorithm, comparable to replaygain, would be used display the value instead of the peak value). This would encourage him to keep to (or even use ) that headroom, shown as upto +20dB, and not use much compression.
MPC playback does not involve (dynamics) compression so the only thing that could affect quality (at playback) is clipping. Every one will agree that clipping must be avoided.

I think Replaygain "remasters" the volume (not realy) so it would be played on a level comparable to what K-20 would give, is this correct?
Then how does the value on the headroom slider relate to that? is 20 replaygain level (the famous 83 dB)? It looks like the oposite of K-20, where -20dB would be called 0 :confused:

thank you very much JohnV

it's come with a new feature ....

this mpc encoder are lastest now ???

why i didn't see these program at Andree Buschmann's mpegplus site or it's still beta ???

Yes, it is latest.
Frank is now the one that mantains and updates mppenc.

Thanks again for the update, Juha, and thank you Roberto and John33 for the icl compiles.

hi,

just wanted to say that my own homepage (www.stud.uni-hannover.de...) is ´"dead", since i don't know when the page and the account will be deleted. i finished university last year...
franks page is now the official software-release site and the 1.01/0.2-series are official.

andree

u made this program .... and u still study at university ???
Waaaaaaaaaaaaw!!!

........thanks to all MPC Developer , i'm very appreciate ur work sooooo much ( and hope SV8 - SVXXX gonna out 4 me sooooooon thx )
