===Encoding===
Orban Opticodec-PC Streaming and File Encoders were the first commercially available encoders supporting [[AAC-LC]]/HE-AAC back in 2003. They are now deprecated and replaced with StreamS Encoders from StreamS/Modulation Index with many more features, including support [[xHE-AAC]]/[[Unified Speech and Audio Coding]]. They are now in use at some of the largest content providers, and are considered to be the standard of the industry for live encoding.

Sony supports HE-AAC encoding since SonicStage version 4.

iTunes 9 supports HE-AAC encoding and playback.<ref>{{cite web|url=https://www.apple.com/itunes/features/#importing |title=Apple - iTunes - Learn about the features of iTunes 10 |access-date=2011-03-29 |url-status=dead |archive-url=https://web.archive.org/web/20110329002415/http://www.apple.com/itunes/features/#importing |archive-date=2011-03-29 }}</ref><ref>{{cite web|url=https://www.apple.com/itunes/features/#radio|title=iTunes|website=Apple|access-date=3 May 2018|url-status=live|archive-url=https://web.archive.org/web/20110329002415/http://www.apple.com/itunes/features/#radio|archive-date=29 March 2011}}</ref>

[[Nero AG|Nero]] has released a free-of-charge command line HE-AAC encoder, [[Nero AAC Codec]],<ref>{{cite web|url=http://www.nero.com/ena/technologies-aac-codec.html|title=Nero AAC Codec|access-date=2009-11-23|url-status=live|archive-url=https://web.archive.org/web/20091211174635/http://www.nero.com/ena/technologies-aac-codec.html|archive-date=2009-12-11}}</ref> and also supports HE-AAC inside the Nero software suite.

Sorenson Media's Squeeze Compression Suite includes an HE-AACv1 encoder and is available for [[macOS]] as well as [[Microsoft Windows|Windows]].

The [[3GPP]] consortium released source code of a reference HE-AACv2 encoder that appears to offer competitive quality.<ref>{{cite web|url=http://www.mp3-tech.org/tests/aac_48/results.html|title=48kbps AAC public test results|date=2006-03-20|access-date=2008-09-05|publisher=MP3'Tech|last=Bouvigne|first=Gabriel|url-status=live|archive-url=https://web.archive.org/web/20080724081344/http://www.mp3-tech.org/tests/aac_48/results.html|archive-date=2008-07-24}}</ref>

[[Winamp]] Pro also supports ripping music to HE-AAC. Using a transcoding plugin for Winamp's media library, any file can be transcoded to HE-AAC.<ref>{{cite web|url=http://www.free-codecs.com/download/Winamp_Transcoder.htm|title=Free Download Winamp Transcoder 2.0|website=www.free-codecs.com|access-date=3 May 2018|url-status=live|archive-url=https://web.archive.org/web/20080820164701/http://free-codecs.com/download/Winamp_Transcoder.htm|archive-date=20 August 2008}}</ref>

[http://tmkk.undo.jp/xld/index_e.html XLD], a macOS audio encoding program, offers encoding from any of its supported formats to HE-AAC.

[[Nokia PC Suite]] may encode audiofiles to eAAC+ format before transmitting them to mobile phone.

HE-AAC v1 and v2 encoders are provided by the [[Fraunhofer FDK AAC]] library in [[Android (operating system)|Android]] 4.1 and later versions.<ref name="Supported Media Formats">{{cite web|title=Supported Media Formats|url=http://developer.android.com/guide/appendix/media-formats.html|publisher=Google|access-date=2013-10-10|url-status=live|archive-url=https://web.archive.org/web/20120311121312/http://developer.android.com/guide/appendix/media-formats.html|archive-date=2012-03-11}}</ref>

===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.
