Press Play to hear a short clip with a single frequency boosted or cut. Your job is to identify which frequency was affected by clicking one of the buttons in the grid. Start with Boost Only and ±12 dB (Easy) — large boosts are much easier to hear while you're building your ear.
As your accuracy improves, reduce the gain step by step (±9 dB → ±6 dB → ±4 dB) to train for subtler differences. Enabling Both directions adds the additional challenge of identifying whether the frequency was boosted or cut.
Each frequency region has a distinct character. A boost at low frequencies adds weight and rumble; in the mids it adds body or honkiness; in the highs it adds brightness or edge. Focus on that character and match it to the frequency cards in the grid.
Use Pink Noise as your starting source — it's spectrally flat, so nothing musical distracts you from the EQ change. Once you're scoring well on pink noise, switch to Loops or One-shots to practice on real music.
The Space/D keys toggle between the filtered and dry signal so you can hear the difference directly.
