Compare measured curves.

One tuning loads on top; pick the opponent with the search bar; the overlay and the shared-signal A/B live below once both are in.

Wearing your own earphones or headphones? Pick them here and the player pre-corrects for their sound, so the demo plays the target tuning itself - not both mixed together.

The comparison

All curves aligned at their 200 Hz–1 kHz mean, so rig level offsets never skew the overlay. Numbers on the axis are dB relative to each curve's own midrange.

Hear them side by side

Wearing your own earphones or headphones? Pick them here and the player pre-corrects for their sound, so the demo plays the target tuning itself - not both mixed together.

Same signal through both tunings at once - slide to blend. Start on pink noise for the clearest read.
