Spill occurs when sound is detected by a microphone not intended to pick it up (for example, the vocals being detected by the microphone for the guitar). [3] Spill is often undesirable in popular music recording, [4] as the combined signals during the mix process can cause phase cancellation and may cause difficulty in processing individual tracks.

This includes the original 6.35mm (quarter inch) jack and the more recent and standard 3.5mm (miniature or 1/8 inch) and 2.5mm (subminiature) jacks, both mono and stereo (balanced) versions. [2] XLR connectors, also known as Cannon plugs, used for analog or digital balanced audio with a balanced line. Digital audio interfaces and interconnects:
Degree of directionality of pickup: in some settings, such as a home video of a birthday party, the person may wish to pick up all the sounds in the room, making an omnidirectional mic desirable. However, if a TV news crew is filming a reporter at a noisy protest, they may only wish to pick up her voice, making a cardioid mic more desirable.
A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone , it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the ...
A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .
Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
As business telephone systems have adopted VoIP technology, support for wideband audio has grown rapidly. Telephone sets from Avaya, Cisco, NEC Unified Solutions, Grandstream, Gigaset, Panasonic (which brands wideband audio "HD Sonic"), Polycom (which brands wideband audio "HD Voice"), Snom, AudioCodes (which brands wideband audio "HDVoIP") and others now incorporate G.722, as well as varying ...
It required the use of a home video tape recorder for storage. [17] November 4–7, 1977: 3M demonstrates a prototype 2-channel 50.4 kHz 16-bit digital recorder running on 1-inch tape at 45 ips at the New York AES Convention. [3] As no true 16-bit converters were available, it combined separate 12-bit and 8-bit converters to create 16-bit ...
