![]() ![]() I also talk to a lot of musicians and bands-some of which are really not happy to what’s done to their music in production just because of what marketing guys tell their labels about "sellability". Unfortunately, there is still the idea of "the louder the better" in the heads of many, even sound engineers and producers, thus depriving us of much detail that really could be present. Sound engineers in production use (or should use) the same algorithms and typically measure short term/momentary LU/LUFS loudness units (as opposed to the VU meters used in earlier times). Loudgain (and other tools) typically measure the integrated loudness of a program (track/album). A "program" as spoken of in EBU documents, can be a single track or sound file as well as a 2-hour set with ReplayGain, this would typically be a single track and/or album.Īnd no, there aren’t currently any "overall" ReplayGain tools that would adapt during a program. ![]() ![]() The idea behind this is to give a lot of headroom for real dynamics (ex: percussion), without clipping, and still give a psychoacoustic model where every part of a program is experienced at "the same loudness" (i.e., no more fiddling with the volume knob). The EBU standardises on a relatively low "center level" of -23 LUFS (-18 LUFS to be used with ReplayGain 2, this is defined to approximately the same as the olden "89 dB" setting of the ReplayGain 1 algorithm). Just compare any good recording made in the 1980s to a newer remaster (take any good Jazz or maybe Floyd album), I think it can be heard. There’s lots of documentation and technical details about loudgain to be found on its GitHub page and also an entry in the Hydrogenaudio In my eyes, much of the dynamics are lost due to modern "loudness war" over-compression techniques. I appreciate feedback and bug reports on usage of the tags with Mp3tag.my hope is that picks up loudgain’s "extended" tags (track & album range and reference loudness) in the tag mapping.Loudgain can be installed natively on Linux, is in ArchLinux’ AUR, available for MacOS X via Homebrew and can be used with Windows 10’s Linux bash. And it can be used with many file types, currently FLAC, Ogg, MP2, MP3, MP4, M4A, AAC, ALAC, Opus, ASF, WMA, WAV, AIFF, WavPack, and APE. Loudgain uses the well-known mp3gain commandline syntax but will never modify the actual audio data. There were never many native Linux tools for replaygaining, so I decided to take over the development of loudgain, a free and open source ReplayGain 2.0 loudness tagger, based on the EBU R128/ITU BS.1770 standard (-18 LUFS). ![]()
