Could you clarify what software or device shows “87 verified”? That would help give a precise answer.
For MP3 files, select ReplayGain normalization if you want volume to be consistent based on how humans perceive sound. For WAV or FLAC files, you may have the option of peak-based normalization.
When applied to normalization targets, an "87%" value historically correlates to legacy audio editing software interfaces that measured volume on a percentage scale rather than decibels. A target of 87% modulation roughly corresponds to a peak amplitude of -1.2 dBFS. This specific threshold is highly valued by creators because it leaves a safe amount of "headroom." Headroom ensures that when the audio is compressed into lossy formats like MP3 or AAC for distribution, it will not introduce digital distortion or inter-sample clipping.

Normalizing tracks individually within an album can destroy the intended artistic dynamics. For instance, an intentional whisper ballad might end up sounding just as loud as an energetic rock song. In these scenarios, utilize "album normalization" functions, which apply a consistent gain adjustment across all tracks based on the loudest song in the collection.
Run a "Test" to find the average and peak volume levels. The software will recommend a maximum volume level to avoid distortion. Choose Normalization Method: Could you clarify what software or device shows
Sound Normalizer 8.7 is a dedicated Windows application from Kanz Software that allows users to adjust the volume levels of various audio formats—including MP3, WAV, FLAC, Ogg, and AAC—to a consistent standard. Unlike complex Digital Audio Workstations (DAWs), this tool focuses on ease of use and batch processing for large libraries. Key Features of Version 8.7
For advanced users, the ability to normalize the left and right audio channels separately is critical. This allows you to correct stereo imbalances where one speaker or side of a recording is quieter than the other. For WAV or FLAC files, you may have
Imagine listening to a classical piece normalized to 0 dB, followed by a rock song also normalized to 0 dB. The classical piece will still sound quiet because its average loudness (RMS) is low. The rock song will sound deafening because its average loudness is high.
