The simplest way to change the duration or pitch of an audio recording is to change the playback speed. For a digital audio recording, this can be accomplished through sample rate conversion. When using this method, the frequencies in the recording are always scaled at the same ratio as the speed, transposing its perceived pitch up or down in ...
A microphone’s sensitivity varies with frequency (as well as with other factors such as environmental conditions) and is therefore normally recorded as several sensitivity values, each for a specific frequency band (see frequency spectrum). A microphone’s sensitivity can also depend on the nature of the sound field it is exposed to.
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 ...
Change the speaker volume and type and specify whether to show the volume icon in the notification area. Change the sounds played for the system or specific programs when a certain event occurs, i.e. Windows Startup or Critical Stop. Change default devices for music playback, recording, voice recognition, MIDI etc.
In the UK, the use of wireless microphone systems requires a Wireless Telegraphy Act license, except for the license-free bands of 173.8–175.0 MHz and 863–865 MHz. These license-free bands are sometimes referred to as "Channel 70" (not to be confused with TV Channel 69, which operated on 854–862 MHz and always required a license from JFMG ...
In real-world photographs, the highest spatial-frequency detail consists mostly of variations in brightness (luminance detail) rather than variations in hue (chroma detail). Most photographic noise reduction algorithms split the image detail into chroma and luminance components and apply more noise reduction to the former or allows the user to ...
The supplied microphone clip is pushed into a groove on the underside of the microphone and mechanically locked with a quick-release button. Many users have complained about the tendency of the supplied microphone clip to let go of the microphone, allowing it to drop, especially when adjusted quickly for instrumental solos, or when mounted to ...
Parabolic microphone used at an American college football game. A parabolic microphone is a microphone that uses a parabolic reflector to collect and focus sound waves onto a transducer, in much the same way that a parabolic antenna (e.g. satellite dish) does with radio waves. Though they lack high fidelity, parabolic microphones have great ...
