Look-ahead is implemented by splitting the input signal and delaying one side (the audio signal) by the look-ahead time. The non-delayed side (the gain control signal) is used to drive the compression of the delayed signal, which then appears at the output. This way a smooth-sounding slower attack rate can be used to catch transients.
Gain staging is the process of managing the relative levels in each step of an audio signal flow to prevent introduction of noise and distortion, feeding the inserts, such as equalizers and compressors with the right amount of signal, particularly in the analogue realm. Ideal gain staging occurs when each component in an audio signal flow is ...
Adobe Premiere Pro is a timeline-based non-linear video editing software developed by Adobe Inc., distributed as part of the Adobe Creative Cloud suite. Primarily aimed at professional video editing, the program also provides an advanced set of tools for creating special effects and visual effects.
Schematic of an AGC used in the analog telephone network; the feedback from output level to gain is effected via a Vactrol resistive opto-isolator.. Automatic gain control (AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input.
Within modern distributed control systems and programmable logic controllers, it is much easier to prevent integral windup by either limiting the controller output, limiting the integral to produce feasible output, [5] or by using external reset feedback, which is a means of feeding back the selected output to the integral circuit of all ...
Dynamic range is therefore the signal-to-noise ratio (SNR) for the case where the signal is the loudest possible for the system. For example, if the ceiling of a device is 5 V (rms) and the noise floor is 10 μV (rms) then the dynamic range is 500000:1, or 114 dB:
Volume control can refer to: Volume controlled continuous mandatory ventilation; Potentiometer, a feature on audio equipment for adjusting the sound level
Error-correcting codes are used in lower-layer communication such as cellular network, high-speed fiber-optic communication and Wi-Fi, [11] [12] as well as for reliable storage in media such as flash memory, hard disk and RAM. [13] Error-correcting codes are usually distinguished between convolutional codes and block codes:
