1. Exploring the Mystery of Music Frequencies

Sound is composed of various frequencies, generally divided into three ranges:

• Low frequencies (20 - 200 Hz): Provide power and depth, such as heavy bass drum beats.

• Mid frequencies (200 Hz - 4 kHz): Contain vocals and most musical instruments.

• High frequencies (5k Hz – 20 kHz): Add clarity and detail, like crisp bird chirps.

Adjusting these frequencies changes the intensity of each frequency band, altering the overall tonal balance. Even small tweaks in each range can significantly affect the sound.

2. Practical Applications and EQ Tips

Practical Applications

Music

• Electronic or rock music: Increasing low frequencies enhances impact and immersion, while slightly reducing mid frequencies helps reduce muddiness and harshness.

• Classical music: Reducing low frequencies and slightly boosting mid-to-high frequencies can emphasize instrumental details and vocal clarity.

Movies and Podcasts

Increasing mid frequencies makes dialogue stand out and sound clearer, while reducing low frequencies minimizes muddiness in the audio.

Common Situations and EQ Tips

Muddy or Overly Bass-Heavy Sound

Reduce the gain around 80 Hz and 150 Hz, and increase the gain above 3 kHz. This helps reduce muddiness and enhances clarity.

Muffled or Dull Vocals

Boost the gain around 600 Hz or 1.2 kHz, and slightly reduce mid-low frequencies. This adjustment makes vocals more spacious and transparent.

Harsh/Weak High Frequencies

Adjust the gain at 5kHz and 9kHz for a balanced tone, and avoid over-boosting only one of them. After tuning, the treble will sound smoother and brighter.
