Etree
etree, or electronic tree, is a music community created in the summer of 1998 for the online trading of live concert recordings. etree pioneered the standards for distributing Lossless data compression, lossless audio on the net and only permits its users to distribute the music of artists that allow the Taper (concert), free taping and trading of their music. The organization describes itselhere Background etree.org was created because collectors and curators of live music recordings historically faced four related problems: First, a problem common to all curators: source material degrades over time. In particular, the magnetic audio tape used to make many live audio recordings physically decays and, as it is repeatedly played back, loses its clarity. Preserving musical source material, therefore, meant restricting access to it. As a result, archival music may have been preserved, but it was not being heard by anyone.

Jammy Award
The Jammy Award (also known as the Jammys) is an awards show for bands typically referred to as jam bands and other artists associated with live, improvisational music, created by Dean Budnick and Peter Shapiro. The Jammys are sponsored by Relix magazine, Jambands.com, and Shapiro. The Jammy Awards returned in 2008 to the WAMU Theater at Madison Square Garden in New York City, after taking a one year break. First Annual Jammy Awards (2000) The First Annual Jammy Awards were held on June 22, 2000, at Irving Plaza in New York City. The event was presented by Jambands.com and executive producers Peter Shapiro and Dean Budnick. Shapiro, who owns the Wetlands Preserve, is the publisher of Jambands.com. Budnick is editor in chief of Jambands.com and also co-hosted The Jammys with Peter Prince of Moon Boot Lover. The evening had two basic components: awards were presented in various categories, and the scene's best bands performed sets of blistering music with special guests. The ide ...

Live Music
A concert is a live music performance in front of an audience. The performance may be by a single musician, sometimes then called a recital, or by a musical ensemble, such as an orchestra, choir, or band. Concerts are held in a wide variety and size of settings, from private houses and small nightclubs, dedicated concert halls, amphitheatres and parks, to large multipurpose buildings, such as arenas and stadiums. Indoor concerts held in the largest venues are sometimes called ''arena concerts'' or ''amphitheatre concerts''. Informal names for a concert include ''show'' and ''gig''. Regardless of the venue, musicians usually perform on a stage (if not actual then an area of the floor designated as such). Concerts often require live event support with professional audio equipment. Before recorded music, concerts provided the main opportunity to hear musicians play. For large concerts or concert tours, the challenging logistics of arranging the musicians, venue, equipment and audi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lossless Data Compression
Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. By contrast, lossy compression permits reconstruction only of an approximation of the original data, though usually with greatly improved compression rates (and therefore reduced media sizes). By operation of the pigeonhole principle, no lossless compression algorithm can efficiently compress all possible data. For this reason, many different algorithms exist that are designed either with a specific type of input data in mind or with specific assumptions about what kinds of redundancy the uncompressed data are likely to contain. Therefore, compression ratios tend to be stronger on human- and machine-readable documents and code in comparison to entropic binary data (random bytes). Lossless data compression is used in many ...

Taper (concert)
A taper is a person who records musical events, often from standing microphones in the audience, for the benefit of the musical group's fanbase. Such taping was popularized in the late 1960s and early 1970s by fans of the Grateful Dead. Audio recording, while not officially allowed until the creation by the band of a "tapers' section" behind the soundboard in the mid-1980s, was generally tolerated at shows and fans would share their tapes through trade. Taping and trading became a Grateful Dead sub-culture. Tapers generally do not financially profit from recording such concerts and record using their own equipment with permission from the artist. Taper recordings are commonly considered legal because the recordings are permitted and distribution is free. Taper etiquette strictly excludes bootlegging for profit. "Stealth taper" is a common term for a person who may furtively bring equipment into shows to record without explicit permission. Although taping is usually done with microp ...

Generation Loss
Generation loss is the loss of quality between subsequent copies or transcodes of data. Anything that reduces the quality of the representation when copying, and would cause further reduction in quality on making a copy of the copy, can be considered a form of generation loss. File size increases are a common result of generation loss, as the introduction of artifacts may actually increase the entropy of the data through each generation. Analog generation loss In analog systems (including systems that use digital recording but make the copy over an analog connection), generation loss is mostly due to noise and bandwidth issues in cables, amplifiers, mixers, recording equipment and anything else between the source and the destination. Poorly adjusted distribution amplifiers and mismatched impedances can make these problems even worse. Repeated conversion between analog and digital can also cause loss. Generation loss was a major consideration in complex analog audio and video ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulse-code Modulation
Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps. Linear pulse-code modulation (LPCM) is a specific type of PCM in which the quantization levels are linearly uniform. This is in contrast to PCM encodings in which quantization levels vary as a function of amplitude (as with the A-law algorithm or the μ-law algorithm). Though ''PCM'' is a more general term, it is often used to describe data encoded as LPCM. A PCM stream has two basic properties that determine the stream's fidelity to the original analog signal: the sampling rate, which is the number of times per second that samples are taken; and the bit depth, which determines the ...

Compact Discs
The compact disc (CD) is a digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as '' Digital Audio Compact Disc''. The format was later adapted (as CD-ROM) for general-purpose data storage. Several other formats were further derived, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video CD (VCD), Super Video CD (SVCD), Photo CD, Picture CD, Compact Disc-Interactive (CD-i) and Enhanced Music CD. Standard CDs have a diameter of and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 MiB of data. Capacity is routinely extended to 80 minutes and 700 MiB by arranging data more closely on the same sized disc. The Mini CD has various diameters ranging from ; they are sometimes used for CD singles, storing up to 24 min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shorten (file Format)
Shorten (SHN) is a file format used for compressing audio data. It is a form of data compression of files and is used to losslessly compress CD-quality audio files (44.1 kHz 16-bit stereo PCM). Shorten is no longer developed and other lossless audio codecs such as FLAC, Monkey's Audio (APE), TTA, and WavPack (WV) have become more popular. However, Shorten is still in use by some people because there are legally traded concert recordings in circulation that are encoded as Shorten files. Shorten files use the .shn file extension. Handling Shorten files Since few players or media writers attempt to decompress Shorten files, a standalone decompression program is usually required to convert to a different file format that those applications can handle. Some Rockbox applications can play Shorten files without decompression, and third-party Shorten plug-ins exist for Nero Burning ROM, Foobar2000, and Winamp. All libavcodec based players and converters support the Shorten codec. Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FLAC
FLAC (; Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio, developed by the Xiph.Org Foundation, and is also the name of the free software project producing the FLAC tools, the reference software package that includes a codec implementation. Digital audio compressed by FLAC's algorithm can typically be reduced to between 50 and 70 percent of its original size and decompresses to an identical copy of the original audio data. FLAC is an open format with royalty-free licensing and a reference implementation which is free software. FLAC has support for metadata tagging, album cover art, and fast seeking. History Development was started in 2000 by Josh Coalson. The bit-stream format was frozen when FLAC entered beta stage with the release of version 0.5 of the reference implementation on 15 January 2001. Version 1.0 was released on 20 July 2001. On 29 January 2003, the Xiph.Org Foundation and the FLAC project announced the incorporat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Transfer Protocol
The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server. FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP). The first FTP client applications were command-line programs developed before operating systems had graphical user interfaces, and are still shipped with most Windows, Unix, and Linux operating systems. Many dedicated FTP clients and automation utilities have since been developed for desktops, servers, mobile devices, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
