SWR2 Archivradio, commonly referred to as Archivradio is an internet radio network by the German public broadcasting corporation SWR.
 It specialises in streaming historic original sounds, interviews, speeches in German language from German audio archives.
 The web radio stream is accompanied by a web portal which provides written information about the currently aired sound segment.
 A major principle of Archivradio is that original sounds are unedited and played back in full length.
 Typical topics in the past have been original recordings by the East German secret police Stasi, the complete proceedings of the first literature congress in Berlin after World War II (Erster Deutscher Schriftstellerkongress) or sounds from World War I, most of them recorded on Phonograph cylinders. Archivradio also gives a voice to the archivists.
 They appear in interviews about the specific topics of the program.
 The internet radio consists mainly of spoken word and only broadcasts music in a specific context.
 Archivradio has no typical presenter; there is only a speaker who briefly announces each title, the date and the source.

Turntablism is the art of manipulating sounds and creating new music, sound effects, mixes and other creative sounds and beats, typically by using two or more turntables and a cross fader-equipped DJ mixer.
 The mixer is plugged into a PA system for live events and/or broadcasting equipment (if the DJ is performing on radio, TV or Internet radio, so that a wider audience can hear the turntablist's music.
 Turntablists manipulate records on a turntable by moving the record with their hand to cue the stylus to exact points on a record, and by touching or moving the platter or record to stop, slow down, speed up or, spin the record backwards, or moving the turntable platter back and forth (the popular rhythmic "scratching" effect which is a key part of hip hop music), all while using a DJ mixer's crossfader control and the mixer's gain and equalization controls to adjust the sound and level of each turntable.
 Turntablists typically use two or more turntables and headphones to cue up desired start points on different records.
