zebio Posted June 18, 2020 Share Posted June 18, 2020 Hi, I wonder if there's a chance to get some USAC / xHE-AAC support. USAC means Unified Speech and Audio Coding. It's 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. it's an ISO and MPEG standard (MPEG-D Part 3): https://en.wikipedia.org/wiki/Unified_Speech_and_Audio_Coding. But it's absolutely not popular at all: until few weeks there was no public encoder available. An Open-Sourced encoder is now available, named exhale: http://www.ecodis.de/audio.htm#mpeg And quality is already stunning at low bitrate. Here is a listening test done with classical music and other music and this free USAC encoder already beats OPUS! : https://hydrogenaud.io/index.php?topic=119333.0 Android 9 and following embed an USAC decoder. iOS 13 also support this new standard. 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!
