These work on amplitude and timing without any loudness perception.Īnd, there is an optional ReplayGain plug-in (which isn’t really ReplayGain but it uses the same/similar loudness perception algorithm ). ( If that’s what it is, it will continuously adjust the volume during the program/song making quiet parts quiet louder and loud parts quieter.)Īudacity’s has a Compressor, Limiter, and Leveler effects can be used to make the loud parts quieter and/or the quiet parts louder.

It attempts to normalize sound levels across programs. Microsoft’s Loudness Equalization doesn’t seem to be associated with particular files or any particular player so I assume it’s some kind of automatic volume control. If you have never heard of Loudness Equalization, it is an audio quality feature that is built into Windows 10.

These use a loudness perception algorithm and they make one volume adjustment before the file starts playing so the dynamics of the program are not messed-with (loud parts of the song remain relatively loud and quiet parts remain relatively quiet). ReplayGain, MP3Gain, and Apple Sound Check all work by pre-scanning the loudness of the file and then adjusting the volume at playback time (or by “permanently” adjusting the volume in the case of MP3Gain). Run that troubleshooter to see if it resolves this problem. in the Window that appears select Troubleshoot Sound Problems. In the task bar, right click on the Sound icon. You can configure several parameters such as action timing, period of average, volume recovery function, target peak level, and so on. I couldn’t find any information about how Microsoft’s Loudness Equalization works… 15 Powerful & Free Audio Sound Equalizer for Windows 10, 11 1. Try with the Troubleshoot Sound Problems. Wale calculates appropriate volume of each app in real time from apps average peak level and try to equalize peak levels of each app to desired level.
