Flac file size after replay gain

[Caipion]

Hi all ,

i just added replay gain to a few albums and hi-res files seems to be about 5-10% smaler after this.

This is a little strange cause cds i ripped seems to have the same size after i added replay gain.

Is this related to the new 1.33 flac version or 24 bit ? (I just upgraded to DBPoweramp 17)

Cheers....

Re: Flac file size after replay gain

You are converting flac >> flac and only using the Replaygain dsp effect?

It is likely the original flac files were compressed with different compression settings.

24/96 FLAC as base file (FLAC 1.3.1)

From 110.791kb to 105.166kb FLAC 1.3.1 to FLAC 1.33 (Level5)
From 110.791kb to 105.136kb FLAC 1.3.1 to FLAC 1.33 (Level5)(With Replay Gain DSP)
From 110.791kb to 110.485kb FLAC 1.3.1 to FLAC 1.33 (Fastest)

So better compression but strange as the file with replay gain is always smaler.

30KB difference, it is likely that tag padding is being removed on the later write of replaygain tags.

So it is updating the file adding replay gain and does like a defrag of the vorbis tag ? Just that i get it

Spoon would know for sure, but generally you have a certain amount of data you can pad (reserve or add on to) at the beginning or end of a file when encoding, so if someone had, say, a 500kb tag padding on each track, and you only needed 470kB to hold the artwork and tags, and did not have a pre-set tag padding size, then that would explain the difference.
