Bit rate required for mono audio object in object-based audio program compressed with MPEG-H 3D Audio

Abstract

Advantage of object-based audio (OBA) is that customization of the reproduced sound by individual listeners is allowed. To design the broadcasting system and transmission line for OBA, bit rate estimation of OBA program is essential; thus, how much bit rate is required for mono audio object is critical information. The bit rate required for mono audio object in OBA program compressed with MPEG-H 3D Audio is investigated using 12 mono test materials in terms of whether the broadcast quality is met. The obtained results are statistically analyzed and the bit rate meeting the broadcast quality and the bit rate of the detection limit for each mono test material is derived.
