ORTF setup. The ORTF stereo technique, also known as side-other-side, is a microphone technique used to record stereo sound. It was devised around 1960 at the now-defunct Office de Radiodiffusion Télévision Française (ORTF). This technique combines both the volume difference and the timing difference as sound arrives on- and off-axis at two ...
PDF is a standard for encoding documents in an "as printed" form that is portable between systems. However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document; whether to use encryption; and whether to preserve additional information from the original document ...
A ribbon microphone, also known as a ribbon velocity microphone, is a type of microphone that uses a thin aluminum, duraluminum or nanofilm of electrically conductive ribbon placed between the poles of a magnet to produce a voltage by electromagnetic induction. Ribbon microphones are typically bidirectional, meaning that they pick up sounds ...
Astatic model D-104 microphone. In 1930, two amateur radio operators, Creed M. Chorpening, W8WR (later W8MJM) and F.H. Woodworth, W8AHW began experimenting with different types of microphones for their "ham" stations. Their mutual friend, Charles Semple, worked for Brush Development Company where he had been experimenting with Rochelle salt ...
The American D-22 and American D-33 microphones are dual- impedance, omnidirectional, dynamic microphones made by the American Microphone Company. They were used extensively in the broadcast industry in the 1950s because of their modern sleek looks and tapered waist design. [1]
Electronic discovery is subject to rules of civil procedure and agreed-upon processes, often involving review for privilege and relevance before data are turned over to the requesting party. Electronic information is considered different from paper information because of its intangible form, volume, transience and persistence.
The proximity effect in audio is an increase in bass or low frequency response when a sound source is close to a directional or cardioid microphone. [1] [2] Proximity effect is a change in the frequency response of a directional pattern microphone that results in an emphasis on lower frequencies. It is caused by the use of ports to create ...
The first version of Sumatra PDF, designated version 0.1, was based on Xpdf 0.2 and was released on 1 June 2006. It switched to Poppler from version 0.2. In version 0.4, it changed to MuPDF for more speed and better support for the Windows platform. Poppler remained as alternative engine for a time, and from version 0.6 to 0.8 it was ...
