MPEG Unified Speech and Audio Coding (USAC) MPEG doc#: N12235Date: July 2011Author: 1 IntroductionAs mobile devices become multi-functional, and multiple devices converge into a single device, it is becoming prevalent for various types of content, including content that is a mix of speech and music, to be played on or streamed to mobile devices. 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. 2020-07-07 · In the example given during the session, Vershen emphasized that “USAC [xHE-AAC] is going to sound better.

USAC (Unified speech and audio coding) is an MPEG codec speech and audio codec defined in ISO/IEC 23003-3. USAC also defines a profile known as the Extended High-Efficiency AAC (xHE-AAC) audio codec which is the latest member of the MPEG AAC codec family. In order to achieve equally good quality for coding audio and speech, USAC employs the proven Jump to navigation Jump to search. Audio compression standard. Unified Speech and Audio Coding (USAC) is an audio compression format and codec for both music and speech or any mix of speech and audio using very low bit rates between 12 and 64 kbit/s.
FDK-AAC v2 is apparently needed to support the format. I don't know if it's possible to get USAC/xHE-AAC support but it would be a big addition to Poweramp (it will be the first Android Player to support this innovative format). Thank you! aac-lcにsbrとps、usacの機能を追加したもの。 USAC (Unified Speech and Audio Coding) は声と音楽のどちらの音質にも重きが置かれるよう作られたツールであり、HE-AAC v2より低いビットレートでもある程度の音質が確保される。
IEC 62574:2011 maps FL/FR to L/R (usually between 30° and 45°) AC-4: L/R are mapped to FLc/FRc and Lw/Rw to FL/FR in table A.42 but it appears that this mapping is conflicting with USAC specifications which maps Lw/Rw to new FRw/FLw; additionally, Lw/Rw are intended to be at +/-60°. exhale-V1.1.4-cc4151b9 for Windows 2021-04-02. exhale, which is an acronym for "Ecodis eXtended High-efficiency And Low-complexity Encoder", is a lightweight library and application to encode uncompressed WAVE-format audio files into MPEG-4-format files complying with the ISO/IEC 23003-3 (MPEG-D) Unified Speech and Audio Coding (USAC, also known as Extended High-Efficiency AAC) standard.
USAC (Unified speech and audio coding) USAC (Unified speech and audio coding) is an MPEG codec speech and audio codec defined in ISO/IEC 23003-3. USAC also defines a profile known as the Extended High-Efficiency AAC (xHE-AAC) audio codec which is the latest member of the MPEG AAC codec family. Extended High Efficiency AAC xHE-AAC – defined in 2012, uses USAC One of many improvements in MPEG-4 Audio is an Object Type called Long Term Prediction (LTP), which is an improvement of the Main profile using a forward predictor with lower computational complexity. Interns usually go on to serve as liaisons between their communities and USAC, return as executive staff members, and even run for student government positions. Lastly, AAC provides programmatic support and resources that aim to enhance students’ educational environment. It converts audio tracks from audio CDs and saves them onto the computer in selected audio file format that can be Extended HE-AAC (USAC), MP3, M4A, Opus, WAV, AAC, FLAC, or other audio file format.

Though afaik USAC is the frequency domain (FD) encoder like AAC for ~48 kbps and higher because AMR-WB+ is useful only at less than 48 kbps. Last Edit : 2012-01-05 19:39:47 by IgorC ECMA 407 used by USAC and includes channel position according to IEC 62574:2011 and has names similar to ITU BS.2051 but with more channel names; ISO/IEC 23001-8:2013/Amd 1:2015 also includes channel position according to IEC 62574:2011 with even more channel position names for MPEG related formats; ETSI TS 102 366 V1.4.1 used by AC-3 and E-AC-3 Android 9 and following embed an USAC decoder.
