Use the 31–125 Hz bands for bass and low-end weight, 250–500 Hz to reduce mud or add warmth, 1–4 kHz for vocal presence, and 8–16 kHz for brightness and air. Start with a preset or move individual sliders, compare the original with the equalized audio, then download MP3 for easy sharing or WAV for an uncompressed result. Processing stays in your browser.
