Who Needs to Use the Loudness Equalization Feature?
If you are a sound engineer or a sound editor, you must take care of the equalization to retain your audience’s attention. Human ears are much sensitive to changes in the audio. They can even sniff a minor audio disruption that can ruin the entire hearing experience.
It does not matter how much you have invested in video making; if your audio is of low quality, it will deviate your listeners from you. For example, If you have not properly set the equalization of your podcast, your audience will find it bothersome to listen to. It will agitate them, and your audience conversion will be badly affected.
Should You Turn Loudness Equalization On or Off?
Equalization works like a charm with voices, but it can create problems while listening to music. If the song has instrumental sounds louder than the singer’s voice or vice-versa, loudness equalization helps to normalize it.
However, you can not get the best experience even using it if the song is equalized that way. The dynamic range of music gets compressed with equalization, which can create issues listening to the music.
For instance, if you are listening to the lecture recordings at your university, you feel that there are many audio pops. You cannot figure out what the lecturer is saying. Those pops can be much louder than the lecturer’s voice and prevent you from listening to the lecture effectively.
Loudness equalization automatically regulates the volume level and provides a consistent sound experience. You won’t have to encounter jarring variance in your volume level. However, you can not expect it to fix issues with the crappy audio.
As a music lover, I recommend you turn on the loudness equalization feature on your computer. It not only enhances your hearing experience but also protects your ear from any harm due to the frequency fluctuations in the audio.
