The eight-band equalizer changes the balance of different frequency regions independently. It can reduce muddiness, emphasize presence or soften a bright mix. Sonic uses a low shelf at 60 Hz, broad bell filters across the middle bands and a high shelf at 16 kHz. The bands overlap, so neighboring adjustments interact.
60 Hz controls the deepest bass using a low shelf. Boost for low-end weight or cut to reduce rumble; small speakers may barely reproduce this range.
150 Hz affects bass body and warmth. Too much can make a full mix boomy, while a moderate cut can leave room for vocals.
400 Hz affects low mids, including the body of guitars and voices. A small cut can reduce boxiness; a large cut can make the recording thin.
1 kHz covers central midrange energy. Boosting can bring instruments forward; cutting can create a more scooped tone but also remove useful vocal body.
2.4 kHz affects presence and articulation. Try small adjustments because strong boosts can make voices and instruments aggressive.
6 kHz affects brightness, attack and many vocal consonants. Cutting can soften harshness; boosting can bring out percussion and hiss.
10 kHz affects high-frequency detail and sparkle. A boost can emphasize existing noise; it cannot restore detail that was never recorded.
16 kHz is a high shelf for the uppermost air in the recording. Its usefulness depends on the source sample rate and your hearing and playback setup. Bands at or above half the sample rate are skipped.
All bands start at 0 dB, which is flat. First identify one problem, then change one band by 2–3 dB and compare. For a muddy mix, try a small 150 or 400 Hz cut before boosting other bands. Every band offers −18 to +18 dB; use the full range mainly for deliberate creative changes.
An equalizer changes the entire mix in each region; it does not isolate instruments or remove only noise. Strong combined boosts can trigger peak protection, reducing the overall output level. Compare at a similar listening volume to avoid mistaking louder for better. Multiple neighboring boosts have a broader effect than a single narrow correction.
All eight bands start at 0 dB. Adjust at least one band, then Apply effects. Flat settings intentionally preserve the original tonal balance.
