Try searching "d02022ha16ahd" (in quotes) on Google or a tech forum (XDA, DIYAudio, 4PDA). Often, the first part identifies the hardware platform (e.g., Rockchip, Allwinner, STM).
High-end DAC chips feature built-in, programmable digital reconstruction filters (e.g., sharp roll-off, slow roll-off, or minimum phase). Patched firmware allows users to manually switch between these filters or inject custom mathematical coefficients to fine-tune the spatial imaging and transient response of the system. 3.
