An xHE-AAC standard is defined as s a total of four profile levels, and each of the profile levels includes USAC profile level 2. The USAC profile level 2 is a profile supporting a decoding function for a mono and stereo signal. Thus, the xHE-AAC standard may need to decode a mono and stereo audio signal through USAC.

Unified Speech and Audio Coding (USAC) became an international standard in 2012 within MPEG-D and provides a significant improvement over MPEG-4 High-Efficiency AAC version 2 (HE-AAC v2) at low bit rates. The decoding model in USAC consists of three paths between the de-multiplex of the transport signal and the decoded frames of content.

Hi, I wonder if theres a chance to get some USAC / xHE-AAC support. USAC means Unified Speech and Audio Coding. Its both the successor of AAC and a member of the AAC family. It was released five years ago and is also a part of the Digital Radio Mondial broadcast technology. its an ISO and MPEG st

- ISO/IEC 13818-7 (MPEG-2 AAC) Standard, defines the syntax of MPEG-2 AAC audio: bitstreams. - ISO/IEC 14496-3 (MPEG-4 AAC, subpart 1 and 4) Standard, defines the syntax of: MPEG-4 AAC audio AAC 코덱은 MPEG-2 Part.7과 MPEG-4 Part.3 규격에 둘 다 포함되어 있으며 MPEG-2 Part.7/MPEG-4 Part.3의 AAC-LC는 일반적으로 흔히 알려진 AAC이고, MPEG-4 Part.3의 AAC는 고효율(High-Efficiency) 고급 오디오 부호화를 뜻하는 HE-AAC(AAC+) 등의 여러 코덱들이 포함되어 있다. If it adds any weight to this enhancement request for FFmpeg to support USAC / xHE-AAC there is now (as of early 2020) an Open Source encoder available: usac와 xhe-aac가 똑같다고 여기기 쉽지만, 엄밀히는 usac는 xhe-aac 프로파일# 중 하나이다. (xHE-AAC = AAC LC + SBR + PS + USAC) xHE-AAC 프로파일에 AAC가 포함된 것은 디코더가 하위호환을 지원해서 기존 AAC 포맷들을 재생할 수 있어야 한다는 것이지 USAC 자체는 MP3 → AAC처럼 기존 AAC와는 다른 코덱이다.
