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.

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.
In the tabletop RPG and video game series Shadowrun, player characters can communicate via subvocal microphones in some instances. In Paranoia, all citizens can speak to the computer via their "cerebral cortech" implants. Alistair Reynolds Revelation Space trilogy frequently uses sub-vocalization systems in various devices.
The public spotlight can feel hot enough as it is, but it can get downright blistering when a live mic, still-rolling camera, or supposedly private text catches politicians, celebrities, or other ...
Contact microphones have been used to pick up the sound of a snail's heartbeat and the footsteps of ants. A portable version of this microphone has recently been developed. A throat microphone is a variant of the contact microphone that picks up speech directly from a person's throat, which it is strapped to. This lets the device be used in ...
To maximize gain before feedback, the amount of sound energy that is fed back to the microphones must be reduced as much as is practical.As sound pressure falls off with 1/r with respect to the distance r in free space, or up to a distance known as reverberation distance in closed spaces (and the energy density with 1/r²), it is important to keep the microphones at a large enough distance ...
For example, if you have a 56kbs dial-up connection to the internet, you will be able to watch videos with a bit rate of 56kbs or less. (A majority of dial-up connections have speeds of 28kbs or less because of issues with the phone lines). If you try to watch a video clip with a bit rate of 300kbs over a dial-up connection, the video will not ...
A laser microphone can be used to reconstruct audio from a laser beam shot onto an object in a room, or the glass pane of a window. Researchers have also prototyped a method for reconstructing audio from video of thin objects that can pick up sound vibrations, such as a houseplant or bag of potato chips. [18]
