So I put the RG in as a permanent modification in the file itself (not in tags but in the sound encoding), and then all these files will be at roughly the same loudness no matter what I play them with, even players that know nothing about ReplayGain.įrom what I’ve read about how this is done under the hood, it only changes a dedicated gain parameter that exists in the MP3 (and MP4) encoding, nothing else is touched. So since I don’t want to take chances on what player I’m gonna put them through in the future, I just take everything down as many dB as necessary until the MP3Gain tool reports the track is no longer encoded with clipping risk (try to make them all ~92 dB but on some I go as low as 89 dB, which is the auto-RG standard if I remember right). I apply RG manually to tracks I buy off Google Play because some of them are shitty MP3 conversions with no headroom, which can decompress as clipped tracks if played with not-smart-enough players.

To what volume did you normalize? The program states that 89 db is default.You’d think any decent implementation of automatic ReplayGain would either be preset to never clip the song (to just not apply RG if it sees it will push it to clipping) or at least offer a visible option to the user, but… yeah, apps still exist that are so stupid they don’t mention this or give you an option, and they do go into clipping (last time I tried this and got bad results was with UAPP).īut yes I do, I absolutely use ReplayGain, just not the automatic version that’s implemented in music players. Right, thank you! I will take a look again. (However, since you can go up or down by 1.5dB, you should be able to get within 3/4ths of a dB, except where limited by clipping.) And MP3Gain adjusts in 1.5dB steps, which is the best you can do without decompressing/recompressing. Two people might not agree on when two songs are 'equal'. Perceived loudness is tricky, especially if you are trying to match different styles of music or very-dynamic music.

MP3Gain uses the ReplayGain loudness algorithm. If you want to match volumes, you'll have to reduce the volume of most songs because plenty of quiet-sounding songs are 0dB normalized. (MP3Gain uses a different dB reference +89dB SPL) and I don't know what that is in LUFS.) With most music you're not going to hit -10dB without clipping, unless you also use lots of dynamic compression. On modern CDs, I notice that many of the tracks Mp3gain reports clipping on the unmodified mp3s. I am using EAC (0.95beta4) / LAME (lame3.97b2) - The mp3s I am ripping are at 320 kBits/s. Did you change the default target loudness setting? If you make the target too loud it won't do anything to most songs unless you allow clipping) because most music is already normalized (maximized) and they can't go any higher (without clipping). I have been playing around with the Mp3Gain program and had some questions. (However, since you can go up or down by 1.5dB, you should be able to get within 3/4ths of a dB, except where limited by clipping.)īut. An option allow to automatically lower gain to not clip audio so you can. And MP3Gain adjusts in 1.5dB steps, which is the best you can do without decompressing/recompressing. This app can boost the volume of your music or other MP3 files several times louder.

MP3Gain uses the ReplayGain loudness algorithm.īut that doesn't work: songs still differ in volume. But it only checks the peak level and then it shifts the peak to the desired levelNo.
