What is an audio equalizer?

An audio equalizer (EQ) is a tool that allows you to adjust the volume of specific frequency bands in an audio signal. It helps you balance the sound by boosting or cutting bass, midrange, and treble frequencies.

What are the best EQ settings for vocals?

For clear vocals, it's generally recommended to cut low frequencies (around 60Hz-250Hz) to remove mud, and slightly boost the high-mids (around 4kHz) to add presence and clarity. Our 'Vocal' preset applies these settings automatically.

Can an equalizer fix bad audio quality?

While an EQ cannot fix severe distortion or clipping, it can significantly improve muddy, thin, or unbalanced audio by reshaping the frequency spectrum to sound more natural and professional.

What is the difference between Bass, Mid, and Treble?

Bass (Low frequencies, e.g., 60Hz) provides depth and punch. Mids (e.g., 250Hz to 4kHz) contain most of the vocal and instrument detail. Treble (High frequencies, e.g., 12kHz) adds brightness, air, and crispness to the sound.
