An equalizer is a tool that helps adjust the sound on electronic devices like music players and radios. It can be used to control the levels of different frequencies, making it easier to hear music or speech more clearly. Essentially, it makes the sound more even and balanced by adjusting the bass, treble, and other settings. If you're trying to hear a song or movie better, an equalizer can help you adjust the sound to your needs.
