Audio Data Interchange Format, a file format to exchange Advanced Audio Coding (AAC) data
AAC supports inclusion of 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 16 low frequency effects (LFE, limited to 120 Hz) channels, up to 16 "coupling" or dialog channels, and up to 16 data streams.
In 2006, the 1996 version of the album was made available for download at Coil's official site, thresholdhouse.com, in aac, mp3, and lossless flac formats.
She became Dolby's representative to the MPEG audio standards committee and served as the Editor of the committee that developed the "Advanced Audio Coding" (AAC) standard that was later brought to mainstream attention by its use in the Apple iPod.
By the late 1980s and the early 1990s, the 45 rpm record would decrease in popularity and other means would be used to evaluate the popularity of new songs, such as cassette-single, CD single, and digital MP3/AAC sales (plus radio airplay).

The U.S. vinyl was re-released in 2006 in digital form on Amazon.com (MP3) and iTunes (AAC).
Spectral band replication (SBR) is a new technique that has gained popularity as an “add-on” to popular perceptual audio codecs such as MP-3 and the Advanced Audio Coding (AAC).
Since September 2005 the show has been produced in two audio formats: an enhanced version, encoded in AAC, and an MP3 version.
Miracast allows a portable device or computer to send, securely, up to 1080p HD video and 5.1 surround sound (AAC and AC3 are optional codecs, mandated codec is linear pulse-code modulation — 16 bits 48 kHz 2 channels).
Decoding MP2 audio is computationally simple, relative to MP3, AAC, etc.
MPEG-4 SLS allows for having both a lossy layer and a lossless correction layer similar to Wavpack Hybrid, OptimFROG DualStream and DTS-HD Master Audio, allowing for backwards compatibility to MPEG AAC-compliant bitstreams.
However this issue is minor because anyone today can play their CD audio music elsewhere as some digital copies (MP3, AAC etc..) or other recordings on an other place.
It occurs in transform-based audio compression algorithms – typically based on the modified discrete cosine transform (MDCT) – such as MP3, MPEG-4 AAC, and Vorbis, and is due to quantization noise being spread over the entire transform-window of the codec.

Avoiding pre-echo is a substantial design difficulty in transform domain lossy audio codecs such as MP3, MPEG-4 AAC, and Vorbis.
There is one side key on the left of the phone; when pressed in standby mode, it opens either the RDS FM radio or the Media Player as selected by the user, allowing playback of WAV/MP3/AAC audio files, and 3GP/MPEG-4 video files.
