Check that no digital clipping or audible distortion has been introduced.
In the world of digital audio normalization, the number refers to decibels (dB) on the ReplayGain and MP3Gain loudness scale. MP3Gain—a free, open-source tool that has become the gold standard for volume normalization—operates on a scale from 87 dB to 105 dB. Within this range, the widely recommended target for most applications is 89 dB. The number 87 sits at the lower end of this spectrum, representing a more conservative, safer normalization target.
If you’re comfortable with the command line, the verify_audio.py script included with the GitHub audio-normalizer tool is an outstanding way to audit your work. It checks the loudness and true peak values of your audio to ensure compliance with broadcast and performance standards. DJs and playlist curators need their mixes to flow smoothly
