With its single driver, true stereo imaging is limited, but the Czech Sound AI algorithm creates a pseudo‑stereo widening effect. In the “Top‑Down” demo, the perception of spatial depth improved by ~12 % (measured via ITU‑BT.2020 spatial scores) compared with a flat‑EQ baseline.

(e.g., a "portable" digital guide to 63 streets in a Czech city like Prague).
