A tool for shaping your headphone soundstage with EQ.
Tap the grid
Each position plays noise at a different frequency range and stereo placement. Drag to select multiple. Arrow keys to move.
Listen to where each position appears
You'll hear each one at a different perceived location. The goal: make them sound as spread out and spatially defined as possible — matching the general layout of the grid.
Shape it with EQ
EQ changes your soundstage. Drag the curve and listen for positions to shift — there's no formula, just experiment.
Test with music
Add tracks from the library and listen. The same EQ applies to everything — grid and music.
Soundstage is a property of your sound system — the range and clarity of spatial positions it can render. Instruments in a song each sit at different positions within that space. The grid simulates this — each position plays a sound at a different spot in that space.
Your results depend on your headphones/speakers and the shape of your ears (called HRTF). There's no single “right” EQ — experiment to find what sounds most defined to you.
Try a large bass boost, a large high-end boost, an upper midrange dip, and sharp narrow peaks and dips in the ultra high end. These can correspond to HRTF cues for spatial positioning and elevation. Select a single position to hear exactly how your changes affect it.
Changing your soundstage can improve clarity, impact, speed, and musicality — but can come at the cost of timbre. I hope this tool helps people hear and improve their soundstage if they want, and I'm curious whether people enjoy the tradeoff. I also hope someone finds the best way to use it.
