Rather than altering the music itself, we apply ReplayGain . This technology analyzes the file and adds tags that tell your media player how to adjust the volume on the fly to match a set standard (usually -18 dB to -23 dB, or around 89dB SPL). Methods for Fixing FLAC Gain (ReplayGain) There are two main ways to handle FLAC gain:
Choose or "Scan selection as tracks." Click "Update File Tags." 2. Loudness Scanner (The Cross-Platform Choice)
A powerful command-line tool included with the official FLAC package. Use the --add-replay-gain command [19].
Choose (recommended for full albums) or Scan selection as tracks . Once the scan finishes, click Update File Tags . Method 2: Foobar2000 Mac (macOS) flac gain fix
This analyzes the entire album as a single unit. It calculates the average loudness of the whole album and applies the exact same volume adjustment to every track. Listening to full albums sequentially.
Best for power users who want to apply specific decibel (dB) offsets via the command line [20]. 3. The Destructive Method (Not Recommended)
Users search for a "fix" because their gain system isn't working as expected. Here are the five most common reasons: Rather than altering the music itself, we apply ReplayGain
Starting in the 1990s and peaking in the 2000s, music producers began heavily compressing audio dynamics. By making the quietest parts of a song louder, the entire track sounded "louder" on the radio.
Engineers started using heavy limiting and compression to make CDs sound as loud as possible.

ReplayGain calculates the average loudness of a track and adds a piece of metadata (a tag) to the file. This tag tells your player to turn the volume up or down by a specific decibel (dB) amount. Why is this better than traditional editing?
