AAC

Advanced Audio Coding (AAC) represents the “state of the art” in audio encoding. It features unprecedented device compatibility with virtually all browsers and mobile devices natively supporting playback of AAC material. The latest addition to AAC formats, xHE-AAC, adds new coding algorithms for ultra-low bitrate encoding, supporting DRC (dynamic range control) for loudness matching and a wide range of available channel configurations and sample rates.

The MainConcept AAC Encoder and Decoder SDKs offer fast, high-quality encoding and decoding of AAC LC, HE v1 and HE v2 audio, making it simple to add support for these extraordinary audio formats to existing applications using up to 7.1 discrete channels. The Fraunhofer AAC Audio Encoder adds VOD as well live xHE-AAC encoding for high-quality audio at even lower bit rates, perfectly suited for adaptive bitrate streaming formats.

AAC has been adopted by major standards organizations including the Third Generation Partnership Programme (3GPP), the Digital Radio Mondiale Consortium (DRM), the Internet Streaming Media Alliance (ISMA), the Bluetooth Special Interest Group, the satellite-based XM Radio, the Japanese Association of Radio Industries and Businesses (ARIB), and many others.

XHE-AAC playback is natively supported on Android (since Android Pie) and iOS (since iOS 13) and is actively deployed by streaming services such as Netflix.
