![]() ![]() This of course can't help a squashed mix, but at least it makes it more bearable.įor the lossless files at home, I rip using album gain (the value is stored in the file but the data remains intact). Most new 2007 releases I've done this with have required average attenuations of -7 to -10dB. For the car, I have a bunch of rewritable CDs, and as I said above, I create mp3s/wmas for the Sandisk. I have a pro soundcard that's hooked up to my home stereo so for home listening, I play these (usually with Foobar2000, incredible piece of software). In fact, the first thing I do with new CDs I get is rip them to my PC as lossless files and process the files with RG. ![]() I've also noticed that RG levels seem to correspond quite well to CDs mastered in the early to mid 80's before the loudness war began. It's not an archive quality format, but it's uses less space) and replaygain has been very useful. I create specific MP3 files of my CDs and needledrops to play in my little Sandisk pocket audio player (and lately WMA. Obviously, if you use the album gain (sometimes called "audiophile") there will be more variations in track levels if the artist intended that. Hence, 1965 Beatles mix with 1972 Led Zeppelin and 2007 Annie Lennox yet all at the same level. ![]() At times, when listening to mixed compilations, it almost makes them sound like they were recorded at the same time, in the same place, with the same levels. It's almost as if it finds the vocal level, and focuses the adjustment on getting all vocals to sound the same. I've been using RG for over a year now and I'm amazed at how well it works at matching levels. Certain frequencies contribute more to human perceptions of loudness than others, so material with more of these frequencies will be attenuated (or boosted less if the change is to be a boost) so that the overall perceived level is the same. That's one part of Replaygain, but there's also the notion of equal loudness curves. I forget the exact standards involved, but I believe it comes from or is based on a SMPTE audio standard for loudness levels in movie theaters. The 89dB is a sound pressure level value that's the default target. Most pop albums, newer ones for sure, and many older ones usually, will have a negative replaygain value - some releases, especially classical, may have positive values.Ĭlick to expand.I don't believe it works on the peak value per se. A high negative value means the CD was mastered very loud and needs to be made quieter according to the reference level. A -8db replaygain value means that on playback the volume level will be reduced by 8db - quieter, in other words. In simple terms, Replaygain uses a maximum db value as a reference (-89db I think). The result should be that there is less variation between perceived loudness of your albums while still maintaining the relativity between album tracks. When playing the tracks you should again choose album gain if you want to use the values you already saved as album tags. Obviously, most critical listeners choose album gain as they want the artist's intentions to be preserved. The track setting means that all tracks are individually given replaygain values so that all tracks have the same perceived loudness. The album setting means that the relative loudness differences between tracks on the album is maintained - every song is given the same replaygain value - which is the value for the loudest track. I've found various threads on HydrogenAudio and it just confuses me.I need "Replay Gain for Dummies"! The burned CD is quieter than original files-why is this? The previously mentioned needledrop-I tried burning it with Replay Gain, album gain, no adjustment to pre-amp. It's a loud CD, so I assume the lower the negative number, the louder the file? Again, when playing multiple albums, what should the playback be-"album gain" or "track gain"?īack to basics-what exactly do the "gain" values mean? Why negative values? For example, Death's Symbolic has album gain of -8 db. ![]() What's going on here? What should I choose in Playback mode? "Track gain" or "Album Gain"? I don't really understand this. The Creative Sounds self-titled comes on, and it's a bit louder. 99 peak, is quieter, more like the Castles. I shuffled tracks and I noticed that the needledrop, which is. I selected all, right click->Replay Gain-> Scan selection as albums. I'm obsessed with correct tags, so that's no problem. I've tried it on a Sabbath playlist, comprising the first six records, mix of pressings (Castle '86, Creative Sounds, Japan, needledrop), so the overall volume varies a bit. I'm now tentatively exploring Replay Gain. I've been using Foobar2000 as my main media player and am getting comfortable with it. Mods, feel free to move this if it isn't appropriate in "Music Corner" ![]()
