It consisted of a microphone in one location and a remote listening post with a speaker that could also be recorded using a phonograph. While also marketed as a device that allowed broadcasting of sounds, or dictating text from one room to a typist in another, it was used in several criminal investigations. [8] [9]
MOD is a computer file format used primarily to represent music, and was the first module file format. MOD files use the “.MOD” file extension , except on the Amiga which doesn't rely on filename extensions; instead, it reads a file's header to determine filetype.
The contact plate is placed directly on the vibrating part of a musical instrument or other surface, and the contact pin transfers vibrations to the coil. 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.
By picking up a larger portion of the vibrating string, more lower harmonics are present in the signal produced by the pickup in relation to high harmonics, resulting in a "fatter" tone. Humbucking pickups in the narrow form factor of a single coil, designed to replace single-coil pickups, have the narrower aperture resembling that of a single ...
A parabolic loudspeaker can be used to test the sound-damping characteristics of materials used for soundproofing. A parabolic loudspeaker is aimed at the material under test, and a parabolic microphone is used to pick up the sound detected on the other side of the material. The difference between the emitted sound and the picked up sound is ...
Coil taps are most commonly found on single coil pickups, and involve adding an extra hook-up wire during manufacture of the pickup so the guitarist can choose to have all the windings of the pickup included in the circuit, for a fatter, higher output sound with more midrange, or switch the output to 'Tap' into the windings at a point less than ...
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.

Picking in both directions (down, up) with a pick is easier. Economy picking, utilizing Alternate picking, is the most efficient technique, however many Russian classical guitarists are able to fluently do this with their fingernails. Tremolo effects (same note repeated in rapid succession) may be easier to achieve.
