![]() ![]() ![]() The problem with that is, I come from the days pre-software, the razor blades and tape era, and then the days of very simply software. I realize I'm perhaps not the typical forum member here because I work professionally in pro audio/video and have for an embarrassingly long time. It seems like we could use just a bit more depth and detail to be really helpful. Once normalization has been applied, it's permanent.Ĭlick to expand.I read your post, tried GB, and failed to accomplish the goal, so the help you gave was good to the point where it got me to try GB again after abandoning it long ago. You can turn off Replay Gain or Sound Check any time. The big difference between normalization and Sound Check/Replay Gain is that normalizing looks at the highest peak and ignores track loudness, then changes the actual data, where Sound Check and Replay Gain use a loudness determining algorithm to establish track volume and apply the correction as a meta-tag leaving the actual audio data unscathed. By contrast, a single loud record tick will not affect the loudness analysis done by Sound Check and Replay Gain. Fortunately, there are also declick functions in Audacity. But be aware that one loud record tick can create the highest peak in the file and establish the normalization level, which won't be what you want. And, understand that Normalization looks only at the highest peak in the entire file, and adjust the entire track level so that peak lands at whatever level you choose. ![]() However, if the track is really, really low, and re-recording is not an option, you can always open the file in Audacity(free audio app) and apply "Normalization" (Effects > Normalize, set for -1dB), but understand this will change the file itself permanently unless you save-as a different filename. Look for it in apps like WinAmp, or Foobar2000. The downside to Replay Gain is there are few apps that can do the file scanning and meta-tagging AND deal with all the different file types. Very much like Sound Check, but more cross-platform. Replay Gain is a similar process, scanning the file, analyzing loudness, and adding a meta-tag that tells the player what adjustment the track volume needs. Using Sound Check helps a lot in avoiding major volume changes between tracks, including your vinyl rips. The sound file itself is not changed other than to have Sound Check metadata added, but playback gain is adjusted during playback. ![]() The way it works is when you import a track, iTunes scans the entire track and comes up with a gain correction that can be applied during playback. Sound Check is Apple's version of "Replay Gain". In iTunes, go to Preferences > Playback and click on "Sound Check". As I only have about half a record album to correct, I'd hope to find something I can download for free as I may never do this again. Is there a program or app I can use that will do this for me. I don't seem to have this capability in the iTunes (version 12.6.1.25) I'm using now on my iMac. I was wondering if there is any facility within iTunes to raise the level of some of the tracks that are lower to match the ones that are hotter before (or during) my transfer to my iTunes library? I seem to recall on my old MacBook computer, on a much earlier version of iTunes, that there was a graphic EQ that could boost frequencies but also boost the overall level of a track, but within limits (like +/- 6db). The hotter tracks are just fine, perfect. Some of the soft ones are so soft, low in volume, as to make them almost unlistenable so I have to correct this. He somehow digitized them and sent them to me as email attachments. He borrowed some equipment to do this and about half the tracks on the record came out very soft, much lower in volume than the other half. I asked a friend to make me a copy of an old vinyl record album from the 60s so I can add it to my iTunes library. ![]()
