Monkey's Audio

APE.apeMonkey's Audio (APE)
Monkey's Audio files use the filename extension .ape for audio, and .apl for track metadata. Like any lossless compression scheme, Monkey's Audio format takes up several times as much space as lossy compression formats like AAC, MP3 and Vorbis. A Monkey's Audio file is 3–5 times as large as a 192 kbit/s bitrate MP3 file. The Shorten format, popular with live taping enthusiasts for years, is no longer in development, but is still in use on some sites such as etree. FLAC has an active development community that continues to refine the format.


MKV.mkvMatroska (MKV)
The Matroska Multimedia Container is an open standard, free container format, a file format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. It is a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in concept to other containers like AVI, MP4, or Advanced Systems Format (ASF), but is entirely open in specification, with implementations consisting mostly of open source software. Matroska file extensions are .MKV for video (which may or may not include subtitles and/or audio), .MK3D for stereoscopic video, .MKA for audio-only files, and .MKS for subtitles only.

As of January 2012, the SoundBridge was no longer available from Roku. As of May 2018, internet radio functionality was no longer supported by Roku. The music is made available by a streaming server, usually a PC running software.

List of Bluetooth profiles

Each A2DP service, of possibly many, is designed to uni-directionally transfer an audio stream in up to 2 channel stereo, either to or from the Bluetooth host. This profile relies on AVDTP and GAVDP. It includes mandatory support for the low-complexity SBC codec (not to be confused with Bluetooth's voice-signal codecs such as CVSDM), and supports optionally MPEG-1 Part 3/MPEG-2 Part 3 (MP2 and MP3), MPEG-2 Part 7/MPEG-4 Part 3 (AAC and HE-AAC), and ATRAC, and is extensible to support manufacturer-defined codecs, such as aptX. Some Bluetooth stacks enforce the SCMS-T digital rights management (DRM) scheme.

Dolby Digital

Dolby Digital 5.1AC3AC-3
Some Sony PlayStation 2 console games are able to output AC-3 standard audio as well, primarily during pre-rendered cutscenes. Dolby is part of a group of organizations involved in the development of AAC (Advanced Audio Coding), part of MPEG specifications, and considered the successor to MP3. Dolby Digital Plus (DD-Plus) and TrueHD are supported in HD DVD, as mandatory codecs, and in Blu-ray Disc, as optional codecs. The data layout of AC-3 is described by simplified "C-like" language in official specifications. An AC-3 stream is a series of frames; The frame size code is used along with the sample rate code to determine the number of (2-byte) words before the next syncword.

Supported filename extensions include MP3 audio with .mp3 and AAC audio with .mp4, .m4a, or .3GP. Audio files can be played from an SD card, with visualizations displayed on the upper screen. Music can be played while the console is closed, using the system's headphone jack. A set of sound manipulation options are available, as well as several audio filters. Ten-second voice recordings can be also be recorded and edited. These can then be shared throughout other applications such as Swapnote. There is also a StreetPass function built-into the app, where users exchange song data to make a compatibility chart between them.

Flash Video

Specifically, Flash Player now supports video compressed in H.264 (MPEG-4 Part 10), audio compressed using AAC (MPEG-4 Part 3), the F4V, MP4 (MPEG-4 Part 14), M4V, M4A, 3GP and MOV multimedia container formats, 3GPP Timed Text specification (MPEG-4 Part 17) which is a standardized subtitle format and partial parsing support for the 'ilst' atom which is the ID3 equivalent iTunes uses to store metadata. MPEG-4 Part 2 video (e.g. created with DivX or Xvid) is not supported.


DVDDVDsextra features
A DVD volume for the DVD-Video format has the following structure of directories and files: IFO files store control and playback information—e. g. information about chapters, subtitles and audio tracks. They do not store any video or audio data or subtitles. BUP files are only backups of the IFO files. Data structures recorded on a DVD-compliant disc are components of one of the four data groups called domains: Video, audio, subtitle and navigation streams are multiplexed and stored on a DVD-Video disc in the VOB container format (Video Object). VOB is based on the MPEG program stream format, but with additional limitations and specifications in the private streams.

CD player

CD playersCDcompact disc player
This market change was initiated in 1998, when the first portable digital audio player, the Rio personal digital music player, was introduced. Portable MP3 players like the Rio competed with portable CD players. The 64 MB version of the Rio MP3 player enabled users to store about 20 songs on the player. One of the benefits of the Rio over portable CD players was that since the Rio had no moving parts, it offered skip-free playback. Since 1998, the price of portable digital audio players has dropped and the storage capacity has increased significantly. In the 2000s, users can "carry [their] entire music collection in a [digital audio] player the size of a cigarette package."

Internet radio

internet radio stationinternetonline
Streaming technology is used to distribute Internet radio, typically using a lossy audio codec. Streaming audio formats include MP3, Ogg Vorbis, Windows Media Audio, RealAudio, and HE-AAC (or aacPlus). Audio data is continuously transmitted serially (streamed) over the local network or internet in TCP or UDP packets, then reassembled at the receiver and played a second or two later. The delay is called lag, and is introduced at several stages of digital audio broadcasting. A local tuner simulation program includes all the online radios that can also be heard in the air in the city. In 2003, revenue from online streaming music radio was US$49 million.

Puddletag is an audio tag (metadata) editor for audio file formats. Under the hood it utilizes Mutagen, a Python module to handle audio metadata. Mutagen supports ASF, FLAC, M4A, APE, MP3, MPC, Ogg Opus, Ogg FLAC, Ogg Speex, Ogg Theora, Ogg Vorbis, True Audio, WavPack, OptimFROG, and AIFF audio files. All versions of ID3v2 are supported, and all standard ID3v2.4 frames are parsed. It can read Xing headers to accurately calculate the bitrate and length of MP3s. ID3 and APEv2 tags can be edited regardless of audio format. It can also manipulate Ogg streams on an individual packet/page level.

44,100 Hz

44.1 kHz44.1kHz44,100 samples per second
This sampling frequency is commonly used for MP3 and other consumer audio file formats which were originally created from material ripped from compact discs. The rate was chosen following debate between manufacturers, notably Sony and Philips, and its implementation by Sony, yielding a de facto standard. The actual choice of rate was the point of some debate, with other alternatives including 44.1 / 1.001 ≈ 44.056 kHz (corresponding to the NTSC color field rate of 60 / 1.001 = 59.94 Hz) or approximately 44 kHz, proposed by Philips. Ultimately Sony prevailed on both sample rate (44.1 kHz) and bit depth (16 bits per sample, rather than 14 bits per sample).


Users can stream or download music in MP3 format (no DRM) without charge before choosing whether to buy or not. (Some MP3s available for free download have Magnatune advertisements in them.) Buyers used to be able to purchase individual albums and choose their own price, from US $5 to $18 per album, but in March 2010 Magnatune moved to a subscriptions-only business model, where buyers have to purchase a monthly subscription (with a three-month minimum) under which they can download as much music as they like from Magnatune. Customers may download music they have purchased in WAV, FLAC, MP3, Ogg Vorbis and AAC encoding formats.

As of May 22, 2011, the Classical Archives database features 12,046 composers, 42,744 recording artists, and 26,697 Albums from 268 labels. These include the classical catalogues of Universal Music Group (Deutsche Grammophon, Decca, Phillips, ECM, etc.), Sony (RCA, Columbia, etc.), Naxos (BIS, Chandos, Hänssler Classic, etc.), and many independent labels through IODA (harmonia mundi, Nimbus, Summit, etc.).

Standard (warez)

0-dayrulesrules and regulations
X264 must be used in an mkv container in combination with an MP2, MP3, AC3, or DTS audio track. On November 15, 2012, the first XXX x264 SD standards were released. The movie file must not be split and an MP4 container must be used. The audio format is AAC. Xvid was used for standard definition rips the years before, just like DivX and SVCD, but did not have a ruleset. The groups Mirage and SMuT had their own list of rules they endorsed visible in their nfos. SMuT wrote: We endorse the following XXX rules and encourage other groups/sites/scene members to insist they are followed also.

Nintendo DSi system software

Nintendo DSi MenudetailsDSi
However, there is an important drawback of the DS Music application, that is, it does not support the popular MP3 format. Instead, the player only supports the AAC format with .mp4, .m4a, or .3GP filename extensions. Furthermore, compared with Sony's PlayStation Portable it is more difficult to interface the DSi with a PC, as there is no USB port on the system. In order to transfer music and podcasts over, users will need to remove the SD Card and plug it directly into their PC. One of the major updates the Nintendo DSi brings to the Nintendo DS line is full network connectivity.

CD ripper

CD rippingripperA list of other CD Rippers
Another term used for the process of ripping Audio-CDs is Digital Audio Extraction (DAE). As an intermediate step, some ripping programs save the extracted audio in a lossless format such as WAV, FLAC, or even raw PCM audio. The extracted audio can then be encoded with a lossy codec like MP3, Vorbis, WMA or AAC. The encoded files are more compact and are suitable for playback on digital audio players. They may also be played back in a media player program on a computer. Most ripping programs will assist in tagging the encoded files with metadata. The MP3 file format, for example, allows tags with title, artist, album and track number information.


Grooveshark was a web-based music streaming service owned and operated by Escape Media Group in the United States. Users could upload digital audio files, which could then be streamed and organized in playlists. The Grooveshark website had a search engine, music streaming features, and a music recommendation system. The legality of Grooveshark's business model, which permitted users to upload copyrighted music, remains undetermined. The company won a major lawsuit filed by Universal Music Group concerning use of Universal's pre-1972 recordings. Grooveshark was also sued for copyright violations by EMI Music Publishing, Sony Music Entertainment, and Warner Music Group.
