Q, short for &acirc;&#128;&#156;quality factor&acirc;&#128;&#157;, is a term in music recording that refers to the peak resonance of an equalizer. Q determines bandwidth of the frequencies to be adjusted by the equalizer. The higher the Q the narrower the bandwidth and vice versa. <br><br>Although defining what Q is may be easy, understanding its affect on audio isn&acirc;&#128;&#153;t so simple. With a high Q (low bandwidth) adjusting the range of the Q produces a a distinct wah-wah sound. <br><br>Properly adjusting the Q of an equalizer is critical before adding compression or unwanted sound artifacts may occur. <br>
