Replaygain and HybridGain

[buzzqw]

Hi all
I quite a newbye in audio encoding so please be kind...

What are the difference between replaygain in lame e hybridgain in Besweet ? Are comparable function ? Or one better than other ?

btw, i try both function and the gain is about the same (replaygain-accurate is just +2db versus hybridgain)
Thanks

~~> HybridGain is a specific mode for BeSweet...and only for this tool.;) It uses 4 differents methods to apply maximal gain on the input file, and achieve 1-pass normalization.

I wonder which are these 4, do you know them (by heart)? Unfortunately I don't, could you list them (for the records), please?

you can see infos about options if you move the cursor over the options in besweetgui

Hybridgain AFAIK is only intended for AC3 to OGG or MP3, and uses azid with a 10dB gain, azid's dialog normalization, postgain to .97 to avoid clipping, and lame's --scale 1 to apply gain to the audio. Thus it is a combination of pre and post gain. I believe this explanation by DSPguru (http://forum.doom9.org/showthread.php?s=&postid=201922#post201922) is still correct.

Edit: Another good link (http://forum.doom9.org/showthread.php?s=&postid=231404#post231404).

Hihi,

thanks, for digging up the info for me.
Now, don't be angry with me, I knew that stuff once, but still I just don't get the number of 4 :confused:

I will check the hovering info in the BeSweetGUI now...

;)

Edit: Ah, O.K., I got it (I mean the 4), KpeX listed them above, and once again next post. I am stupid, that's for sure, but also slow as I edited my post too late it seems.

1. Dialog normalization (-azid -n1/-n0)
2. 10 db gain (-azid -g 10db)
3. Postgain (-ota -G max)
4. Scaling in lame (-lame --scale 1) could be considered a fourth method but it keeps the audio level where it is.
