Bass, mids, and treble are the three primary frequency divisions used to describe sound character in audio equalizers. Bass represents low frequencies (20 Hz to 250 Hz), mids represent middle frequencies (250 Hz to 4 kHz), and treble represents high frequencies (4 kHz to 20 kHz). Reev EQ lets users adjust bass, mids, and treble via quick rotary controls or full 10-band EQ faders.
1. Bass (20 Hz – 250 Hz)
Bass encompasses low-frequency energy including sub-bass rumble, kick drums, basslines, and low cello notes. Adequate bass adds warmth and rhythmic impact, while excessive bass makes audio sound boomy or muffled.
2. Mids (250 Hz – 4 kHz)
Midrange contains the vast majority of human speech, lead vocal melodies, guitars, and piano fundamentals. Balancing the mids is critical for dialogue clarity and natural instrument tonality.
3. Treble (4 kHz – 20 kHz)
Treble consists of high frequencies such as cymbals, vocal sibilance, violin overtones, and acoustic air. Boosting treble increases brightness and sharpness, while cutting treble creates a warmer, softer sound character.
