New DSEE HX AI analyses song type

Audio upscaling is improved even further by our new DSEE HX processor which intelligently recognises instrumentation and musical genres. Realism and liveliness of different instruments, including the human voice, are inherently characterised by high frequency harmonics. By identifying instruments, and the relative energy of the audio, our enhanced DSEE HX can accurately rebuild audio lost during digital compression, for a full fidelity experience even with heavily-compressed audio formats.
