For music-quality audio, 44.1 and 48 kHz sampling rates are the most common. Master recording may be done at a higher sampling rate (i.e. 88.2, 96, 176.4 or 192 kHz). High-resolution PCM recordings have been released on DVD-Audio (also known as DVD-A), DualDisc (utilizing the DVD-Audio layer), or High Fidelity Pure Audio on Blu-ray.
Frances Densmore and Blackfoot chief Mountain Chief working on a recording project of the Bureau of American Ethnology (1916).. Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects.
Situational circumstances: Sometimes a microphone should not be visible, or having a microphone nearby is not appropriate. In scenes for a movie the microphone may be held above, out of the picture frame. Processing: If the signal is destined to be heavily processed, or mixed down, a different type of input may be required.
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 ...
The dynamic range of an audio system is a measure of the difference between the smallest and largest amplitude values that can be represented in a medium. Digital and analog differ in both the methods of transfer and storage, as well as the behavior exhibited by the systems due to these methods.
Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impact the user's perception of the system.
At 30th Street, a line was run from the mixing console down into a low-ceilinged, concrete basement room—about 12 by 15 feet in size—anywhere we set up a speaker and a good omnidirectional microphone." [12] In binaural re-recording, a binaural microphone is used to record content being played over a multi-channel speaker set-up.
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. [2]
