ITunes 9.2 and iOS 4 include full decoding of HE-AAC v2 parametric stereo streams. HE-AAC is also used by AOL Radio and Pandora Radio clients to deliver high-fidelity music at low bitrates. The Nero AAC Codec supports decoding HE and HEv2 AAC. 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, SonicStage and Die Plattenkiste.

HE-AAC v1 and v2 encoders are provided by the Fraunhofer FDK AAC library in Android 4.1 and later versions.
Nokia PC Suite may encode audiofiles to eAAC+ format before transmitting them to mobile phone. XLD, a macOS audio encoding program, offers encoding from any of its supported formats to HE-AAC. Using a transcoding plugin for Winamp's media library, any file can be transcoded to HE-AAC.

The 3GPP consortium released source code of a reference HE-AACv2 encoder that appears to offer competitive quality. Sorenson Media’s Squeeze Compression Suite includes an HE-AACv1 encoder and is available for macOS as well as Windows.

Nero has released a free-of-charge command line HE-AAC encoder, Nero AAC Codec, and also supports HE-AAC inside the Nero software suite. ITunes 9 supports HE-AAC encoding and playback. Sony supports HE-AAC encoding since SonicStage version 4. 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. 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. Orban Opticodec-PC Streaming and File Encoders were the first commercially available encoders supporting AAC-LC/HE-AAC back in 2003. This usually results in the high-end, or treble, portion of the audio signal missing from the audio product. MPEG-2 and MPEG-4 AAC-LC decoders without SBR support will decode the AAC-LC part of the audio, resulting in audio output with only half the sampling frequency, thereby reducing the audio bandwidth. In 2011, a public listening test comparing the two best-rated HE-AAC encoders at the time to Opus and Ogg Vorbis indicated statistically significant superiority at 64 kbit/s for Opus over all other contenders, and second-ranked Apple's implementation of HE-AAC as statistically superior to both Ogg Vorbis and Nero HE-AAC, which were tied for third place. The test, taking bitrate distribution and RMSD into account, is a tie between mp3PRO, HE-AAC and Ogg Vorbis.įurther controlled testing by 3GPP during their revision 6 specification process indicates that HE-AAC and HE-AAC v2 provide "Good" audio quality for music at low bit rates (e.g., 24 kbit/s). Testing indicates that material decoded from 64 kbit/s HE-AAC does not quite have similar audio quality to material decoded from MP3 at 128 kbit/s using high quality encoders. , ISO/IEC 14496-3:2001/Amd.1:2003 andĪt the time, Coding Technologies had already begun using the trade names AAC+ and aacPlus for what is now known as HE-AAC v1, and aacPlus v2 and eAAC+ for what is now known as HE-AAC v2. Parts of the HE-AAC specification had previously been standardized and published by various bodies in
HE-AAC v1 was standardized as a profile of MPEG-4 Audio in 2003 by MPEG and published as part of the ISO/IEC 14496-3:2001/Amd 1:2003 specification. Subsequently, Coding Technologies submitted their SBR mechanism to MPEG as a basis of what ultimately became HE-AAC. Video: 3GPP, AVI, DivX, H.263, H.264 / MPEG-4 Part 10 / AVC video, H.The progenitor of HE-AAC was developed by Coding Technologies by combining MPEG-2 AAC-LC with a proprietary mechanism for spectral band replication (SBR), to be used by XM Radio for their satellite radio service.Audio: AAC, AAC+ / aacPlus / HE-AAC v1, AMR / AMR-NB / GSM-AMR, AMR-WB, aptX / apt-X, aptX HD / apt-X HD / aptX Lossless, eAAC+ / aacPlus v2 / HE-AAC v2, FLAC, MIDI, MP3, OGG, WMA, WAV, LDAC.
