The files are modified? That's about it, really... I guess if you drive it to clipping, then it doesn't have a peak tag for an RG-supporting player to scale down with.
Maybe someone with more insight can comment on this.
If i only want to write to the global gain header of an MP3file (and not worry about writing the ReplayGain tags), what actions do i take in the GUI?
I've read that hitting the "track analysis" button will modify the "volume bits" (i assume that is the global gain header) but in my experience i have to hit the "Gain" button to actually alter the volume of the files.
I'd like to modify the volume of my MP3s so they play consistently in my iPod as well as my Squeezebox.
if sounds like if i do an "analysis" with MP3Gain that it will write RG tags to the files
if that's correct, why don't the files show an new "date modified" value in Windows Explorer?
And when does it actually write the tags?
if you load a bunch of files in and do an analysis, it will tell you how the files differ from the target volume value. But if you change the target volume value, it immediately updates the difference amount for all the files -- but too quickly to actually be writing to the files. Is "analysis" really writing anything to the files?
PS. Please excuse my mediocre English. I hope it's enough to be roughly understood, though.
If you had not said anything then I never would have guessed that English wasn't your native language, so stop apologising.
Here is a - from my understanding - safe procedure to have BOTH, mp3gain-style block-modification and foobar-style RG-tagging:- use mp3gain or foobar to apply ALBUMGAIN to the individual frames. Leave the target-value at the de-facto standard 89db. Do not bother adding undo-information.- then scan the mp3 with foobars replaygain and add RG-tagfields for albumgain and trackgain.[...]
I have one stupid question....Turning an MP3 gain down to -8.0dB and then playing it on a stereo with volume much louder than the original gain it had (playing at let's say +8.0dB) will it have the exact sound/feeling/bass/treble/stuff that the original gain?I ask this because I have read "replaygain" is not perfect. So just making sure...
There will be no difference in the overall sound of the track because all frequencies are affected by the same amount of gain change (no equalizing is done). Howewer, if there's a very quiet sound in a certain frequency area, which was hardly audible even on original gain, it may sink under the noise-floor of your playback equipment when lowering the gain. But i guess this is rather a theoretical concern because most music produced today is heavily dnr-compressed, so that there shouldn't be much of a risk this could actually produce audible consequences...
7.5dB or 9dB - mp3gain only works in multiples of 1.5dB.With 24 bit decoding from a 16 bit source - identical, except any decoder related clipping will be removed.With 16 bit decoding from a 16 bit source - identical, except any decoder related clipping will be removed, and any information in the last 1 or 2 bits will be rounded away or dithered depending on the decoder (i.e. effectively noise is introduced at -96dB in the final 16-bit decode).
Hmm... I sometimes DO NOTICE some kind of ANNOYANCE when I replaygain very clip-pressed albums and play them "as the old good CD back in the 80's". It just doesn't sound the same, and the sound gets really flat.
I just never knew what that was... you put it right... "if there's a very quiet sound in a certain frequency area, which was hardly audible even on original gain, it may sink under the noise-floor of your playback equipment when lowering the gain." I actually find this very annoying and end up not applying the ReplayGain on the songs for the stereo playback. (on the PC with headphones is fine).
oh yes it's placebo and the dogma of the enigma is outbursting into a ship clouded by noise shaping skull nonbrain case of /mnt but you're not root then you can't do it.
