The NutcrackerThe Nutcracker (Shchelkunchik), Op. 71, is an 1892 two-act classical ballet (balet-feyeriya) by Pyotr Ilyich Tchaikovsky, set on Christmas Eve at the foot of a Christmas tree in a child's imagination. The plot is an adaptation of E. T. A. Hoffmann's 1816 short story The Nutcracker and the Mouse King. The ballet's first choreographer was Marius Petipa, with whom Tchaikovsky had worked three years earlier on The Sleeping Beauty, assisted by Lev Ivanov.
Electrical transcriptionElectrical transcriptions are special phonograph recordings made exclusively for radio broadcasting, which were widely used during the "Golden Age of Radio". They provided material—from station-identification jingles and commercials to full-length programs—for use by local stations, which were affiliates of one of the radio networks. Physically, electrical transcriptions look much like long-playing records that were popular for decades.
Mastering (audio)Mastering, a form of audio post production, is the process of preparing and transferring recorded audio from a source containing the final mix to a data storage device (the master), the source from which all copies will be produced (via methods such as pressing, duplication or replication). In recent years digital masters have become usual, although analog masters—such as audio tapes—are still being used by the manufacturing industry, particularly by a few engineers who specialize in analog mastering.
Sonic artifactIn sound and music production, sonic artifact, or simply artifact, refers to sonic material that is accidental or unwanted, resulting from the editing or manipulation of a sound. Because there are always technical restrictions in the way a sound can be recorded (in the case of acoustic sounds) or designed (in the case of synthesised or processed sounds), sonic errors often occur. These errors are termed artifacts (or sound/sonic artifacts), and may be pleasing or displeasing.
DictaphoneDictaphone was an American company founded by Alexander Graham Bell that produced dictation machines. It is now a division of Nuance Communications, based in Burlington, Massachusetts. Although the name "Dictaphone" is a trademark, it has become genericized as a means to refer to any dictation machine. The Volta Laboratory was established by Alexander Graham Bell in Washington, D.C. in 1881.
AudiobookAn audiobook (or a talking book) is a recording of a book or other work being read out loud. A reading of the complete text is described as "unabridged", while readings of shorter versions are abridgements. Spoken audio has been available in schools and public libraries and to a lesser extent in music shops since the 1930s. Many spoken word albums were made prior to the age of cassettes, compact discs, and downloadable audio, often of poetry and plays rather than books.
