Editing High-Efficiency Advanced Audio Coding (section)

===Decoding===
HE-AAC is supported in the [[open source]] FAAD/[[FAAD2]] decoding library and all players incorporating it, such as [[VLC media player]], [[Winamp]], [[foobar2000]], [[Audacious Media Player]] and [[SonicStage]].

The [[Nero AAC Codec]] supports decoding HE and HEv2 AAC.

HE-AAC is also used by [[AOL Radio]] and [[Pandora Radio]] clients to deliver high-fidelity music at low bitrates.

iTunes 9.2 and iOS 4 include full decoding of HE-AAC v2 parametric stereo streams.
* iTunes 9 thru 9.1, iPhone OS 3.1 and Fall 2009 iPods have support for HE-AAC playback for version 1 with no parametric stereo.
* Older versions of Apple [[iTunes]], [[iPod Touch]], and [[iPhone]] will play HE-AAC files at reduced fidelity because they ignore the spectral-band replication and parametric stereo information, instead playing them as though they were standard AAC-LC files without the high-frequency, or "treble," information that is only present in the SBR part of the signal.<ref>{{Cite web|url=https://support.apple.com/en-us/HT1709|title=iPod touch: Supported file formats|website=Apple Support|language=en|access-date=2019-04-07}}</ref> These will report the track length as twice its actual length.{{Citation needed|date=September 2009}}

Dolby released Dolby Pulse decoders and encoders in September 2008. HE-AAC v2 is the core of Dolby Pulse so files and streams encoded in Dolby Pulse will playback on AAC, HE-AAC v1 and v2 decoders. Conversely files and streams encoded in AAC, HE-AAC v1 or v2 will playback on Dolby Pulse decoders.

Dolby Pulse provides the following additional capabilities beyond HE-AAC v2:
* Ability to intelligently generate and insert reversible loudness normalization and dynamic range metadata into the encoded file/stream; this metadata can then be used to optimize the playback experience based on application and/or device.
* Ability to insert custom metadata into the encoded file, and extract this metadata on playback

Dolby has additionally released a PC decoder as an SDK suitable for integration into PC applications requiring Dolby Pulse, HE-AAC or AAC playback capabilities.

HE-AAC v2 decoders are provided in all versions of Android.<ref name="Supported Media Formats"/> Decoding is handled by [[Fraunhofer FDK AAC]] since Android version 4.1.
