Adjust the sound quality in Apple Music on Windows
With the Apple Music equalizer, you can fine-tune specific frequencies of the sound spectrum. You can customize the sound for different genres, rooms in your home, or specific speakers. You can choose from more than 20 presets of the most commonly used equalizer settings, or adjust the settings manually and save your customized settings as a preset that you can use again.
You can also add depth and enliven the quality of your music by adjusting the Sound Enhancer.
