Track Gain vs Album Gain: What’s the Difference and Which Should You Use?
Track Gain adjusts every song independently so that each one matches MP3Gain’s target volume (89 dB by default) on its own. Album Gain analyzes a whole album, works out a single adjustment for the group, and applies that same adjustment to every track — so the quiet songs on the album stay quiet relative to the loud ones. Use Track Gain for shuffled, mixed listening; use Album Gain when you play albums in order, especially classical music, live recordings, and concept albums where the volume differences between tracks are part of the work.
The difference in one table
| Track Gain | Album Gain | |
|---|---|---|
| What is measured | Each file on its own | All files in the album together, as one unit |
| What is applied | A different adjustment per song | One shared adjustment for every song |
| Result | Every song sounds equally loud | The album matches the target, but its internal loud and quiet contrasts survive |
| Best for | Shuffle, playlists, singles, mixed folders | Full albums played in order |
Both modes come from the ReplayGain system, where they were originally nicknamed “Radio Gain” (every song equal, like a radio station) and “Audiophile Gain” (the album preserved as the artist sequenced it). MP3Gain simply gives them plainer names.
What Track Gain actually does
Run Track Analysis and MP3Gain reports, for each file, how far its perceived loudness sits from the target volume. Apply Track Gain and each file is corrected by exactly that amount: a quiet rip from a 1980s CD might come up by 6 dB while a loud modern master is pulled down by 8 dB. Afterwards, any song can follow any other — a ballad after a metal track — without a lunge for the volume knob. That is why Track Gain is the right default for the way most people listen most of the time: shuffled libraries, workout playlists, car USB sticks, and folders of unrelated singles.
The cost is that Track Gain deliberately erases intended contrasts between songs. If an album opens with a whispered intro that is meant to be quiet before the first full track lands, Track Gain will lift that intro to full target loudness and the moment is gone.
What Album Gain actually does
Album Analysis treats the selected files as a single body of music. It measures the loudness of the whole set, calculates one correction that brings the album as a whole to the target, and applies that identical correction to every track. A track that was 4 dB quieter than its neighbour is still 4 dB quieter afterwards — the entire album simply sits at the right overall level next to the rest of your library.
This is the only correct choice for music whose dynamics span tracks: classical works (a hushed adagio movement should not be pumped up to match the finale), live albums, musicals, and any record sequenced as a continuous listen. It also protects gapless albums, where one track flows into the next.
Decision table: which one for your listening?
| Situation | Use | Why |
|---|---|---|
| Shuffle / party / mixed playlists | Track Gain | Every song must stand on its own at the same loudness |
| Complete albums, played in order | Album Gain | Preserves the album’s internal loud/quiet design |
| Classical music | Album Gain | Movements are deliberately recorded at very different levels |
| Homemade compilations (songs from many albums) | Track Gain | There is no shared “album” to preserve — the songs are strangers |
| Singles and one-off downloads | Track Gain | No album context exists |
| Podcasts and audiobooks | Track Gain | Episodes and chapters should each be equally intelligible |
The mistake to avoid: Album Gain on a random folder
Album Gain is only meaningful when the selected files genuinely form one album. If you select your entire mixed library and click Album Gain, MP3Gain will faithfully compute one shared adjustment for thousands of unrelated songs — which changes almost nothing per song and leaves your loudness problem exactly where it was. The mirror-image mistake is applying Track Gain to a classical album and wondering why the quiet movement now blasts. When in doubt, think about how you will listen, not how the files are stored. The button-by-button guide shows which of MP3Gain’s four Analysis/Gain buttons corresponds to each mode, and the step-by-step tutorial walks a full library through the process.
One more reassurance: whichever you choose, nothing is permanent. MP3Gain stores its analysis and undo data in the file’s tag, so you can undo an Album Gain pass next week and redo the same files with Track Gain if your listening habits change. The two modes are strategies, not commitments.
Frequently asked questions
Can I apply both Track Gain and Album Gain?
Applying one after the other is pointless: the second application overwrites the effect of the first, because both write the file’s gain. Pick the mode that matches how you listen. You can always undo and switch — the change is fully reversible.
Which mode is better for shuffle play?
Track Gain. In shuffle, every song must match the target on its own, which is exactly what Track Gain enforces. Album Gain would leave quiet album tracks quiet even when they land next to loud singles.
Does Album Gain change the order or the gaps between tracks?
No. It changes only each file’s gain value, by the same amount for the whole album. Track order, gaps, and the audio itself are untouched — the adjustment is lossless and reversible.
My album has one very loud track. Will Album Gain still work?
Yes, but the loud track dominates the shared calculation, and if you have the “Don’t clip” option on, its peaks can limit how far the whole album is raised. That is correct behaviour: the album keeps its shape, even if it ends up slightly under the target.
