Abstract: Next-generation audio (NGA) delivers personalized audio experiences based on the listener's preference, loud-speaker configurations, and rendering algorithms in the listening environments. A prototype of NGA production equipment was arranged to verify the NGA live-production workflow and produce the typical personalized NGA programs. It consisted of our developed NGA console, NGA loudness meter, and MPEG-H 3DA-complied coding system supporting the Audio Definition Model (ADM) and the serial representation of ADM (S-ADM). Subjective tests were conducted to verify the reasonability of the loudness measurement method to develop the NGA loudness meter using several rendering conditions, including loudspeaker configurations and rendering algorithms. The results showed that the differences between objective and subjective loudness of NGA programs are comparable to those of channel-based audio programs.
