  2. Measurement microphone calibration - Wikipedia

    en.wikipedia.org/wiki/Measurement_microphone...

    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.

    Nintendo 64 controller. The Nintendo 64 controller (NUS-005) is an "m"-shaped controller with 10 buttons (A, B, C-Up, C-Down, C-Left, C-Right, L, R, Z, and Start), one analog stick in the center, a digital directional pad on the left side, and an extension port on the back for many of the system's accessories.

    Echo cancellers must be adaptive because the characteristics of the near-end's speaker and microphone are generally not known in advance. The acoustical attributes of the near-end's room are also not generally known in advance, and may change (e.g., if the microphone is moved relative to the speaker, or if individuals walk around the room ...

    S (signing) outputs a tag t on the key k and the input string x. V (verifying) outputs accepted or rejected on inputs: the key k, the string x and the tag t. S and V must satisfy the following: Pr [ k ← G(1 n), V( k, x, S(k, x) ) = accepted] = 1. [5] A MAC is unforgeable if for every efficient adversary A

    A hyper-cardioid microphone is similar to cardioid, but with a slightly larger figure-8 contribution, leading to a tighter area of front sensitivity and a smaller lobe of rear sensitivity. It is produced by combining the two components in a 3:1 ratio, producing nulls at 109.5°.

  7. Intel High Definition Audio - Wikipedia

    en.wikipedia.org/wiki/Intel_High_Definition_Audio

    Motherboards typically do not have any more than eight built-in output channels (7.1 surround sound) and four input channels (back and front panel microphone inputs, and a back-panel stereo line-in). Users requiring more audio I/Os will typically opt for a sound card or an external audio interface , as these provide additional features that are ...

    These errors include non-recoverable internal system chipset errors, corruption in system memory such as parity and ECC errors, and data corruption detected on system and peripheral buses. On some systems, a computer user can trigger an NMI through hardware and software debugging interfaces and system reset buttons.

    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.
