Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio.
In the Control Systems jargon, the DLL is a loop one step lower in order and in type with respect to the PLL, because it lacks the 1/s factor in the controlled block: the delay line has a transfer function phase-out/phase-in that is just a constant, the VCO transfer function is instead G VCO /s. In the comparison made in the previous sentences ...
During the 1960s a new series of 'sound effect' comedies began with Dick Lester, Spike Milligan and Peter Sellers's Running Jumping & Standing Still, continued through Eric Sykes's The Plank, Barbara Windsor's San Ferry Ann and included four films with Ronnie Barker: A Home of Your Own, Futtock's End, The Picnic, and By the Sea.
One way of stretching the length of a signal without affecting the pitch is to build a phase vocoder after Flanagan, Golden, and Portnoff.. Basic steps: compute the instantaneous frequency/amplitude relationship of the signal using the STFT, which is the discrete Fourier transform of a short, overlapping and smoothly windowed block of samples;
Thus, a minute or so later, the broadcaster would again have full delay, often leaving the listener unaware that material had been deleted. In modern systems, a profanity delay can be a software module manually operated by a broadcast technician that puts a short delay (usually, 30 seconds) into the broadcast of live content.
A delay-line oscillator is a form of electronic oscillator that uses a delay line as its principal timing element. The circuit is set to oscillate by inverting the output of the delay line and feeding that signal back to the input of the delay line with appropriate amplification. The simplest style of delay-line oscillator, when properly ...
A computer-animated film is an animated film that was created using computer software to appear three-dimensional.While traditional 2D animated films are now [when?] made primarily with the help of computers, the technique to render realistic 3D computer graphics (CG) or 3D computer-generated imagery (CGI), is unique to computer animation.
