06 AUDIO STUDIO

A second track: Audio Studio

For people who already own the hardware — plug in and tune, no drivers to install. A standalone platform, not an add-on to the product pages.

  • Device detectionPlug in and the model is identified automatically, reading current firmware and capability bits.
  • PEQ tuningParametric equalisation per band — adjust gain and frequency, audition changes in real time.
  • Preset savingSave a tuned profile, reuse it across devices, or write it back to device firmware.
