The lower you decide to set your aimed loudness, the less you will be prone to experiencing possible problems with clipping. So, depending on your personal preferences and equipment you can decide for yourself what works best for you. I believe that platforms such as YouTube, Spotify and iTunes Radio aim for different ranges somewhere between -9 and -16 LUFS Pretty much all serious and professional audio software uses these LUFS scales.Ĭommon target settings for professional (broadcasting) audio is to aim for -24 LUFS.īut for personal audio use you will probably want to aim higher. setting it to -9 dB will result in -27 LUFS. It sets the perceived loudness to -18 LUFS.Īnd for every increase/decrease by a dB, it will raise/lower the targeted LUFS with the same value. So, if you set the slider to the 0 dB, nothing is actually 'set to 0 dB'. You can consider it as some reference to the old RG standard, and it suggests it will give results comparable with a default setting that was often used for RG.īut as they are very different algorithms, the results will often not be a close match. (It's a common misunderstanding, even with some experienced MB users) The '0' setting that MusicBee shows in the slider has nothing to do with any 'zero' at all. If you would compare results of RG vs R128, especially when using varying content such as rock music, classical music, podcasts, audiobooks, etc, you'll immediately notice that R128 will match those all to a much more uniform perceived loudness. Remember that that is what these algorithms try to accomplish: analyse and simulate the perceived loudness of sound for the average human.Ī dog or a goldfish would need a very different algorithm.Īnd even one person might experience the end result different than another person. The latter is vastly superior in matching how our ears and brain experience the loudness of sound. In the past MusicBee also used ReplayGain (which is what I believe MP3Gain is still using as the engine?), but nowadays MB uses the EBU R128 algorithm. There are a couple of important things to understand. And, if they're playing at different volumes with Replaygain turned off, it's a problem with how they're being processed in MP3Gain. The point of MP3Gain is that additional adjustments don't need to be made by the player. So, if you've run the files through MP3Gain, you should have MB's volume adjustments off. MP3Gain does write a tag, but that is an "undo" tag that tells it how to remove the adjustment it made. The scale factor modification can be reversed using the information in the added tag and the tag may be removed. It.modifies the overall volume scale factor in each MP3 frame, and writes undo information as a tag (in APEv2, or ID3v2 format) making this a reversible process. That's the whole point of MP3Gain - that players will not need to do additional adjustments to get everything playing at the same volume because the file itself is played at the standard volume. The file is already adjusted, by MP3Gain, to be the "normalized" volume. The file will show no calculated volume adjustment in MB because there is no replaygain tag. MP3Gain, from what I understand, adjusts the actual gain within the file. Yes, I conflated two things not thinking.
