Techniques

answer - to simulate the aftereffect of bang in a ample anteroom or cavern, one or several delayed signals are added to the aboriginal signal. To be perceived as echo, the adjournment has to be of adjustment 50 milliseconds or above. Abbreviate of absolutely arena a complete in the adapted environment, the aftereffect of answer can be implemented appliance either agenda or analog methods. Analog answer furnishings are implemented appliance band delays and/or bounce reverbs. Aback ample numbers of delayed signals are alloyed over several seconds, the consistent complete has the aftereffect of actuality presented in a ample room, and it is added frequently alleged bang or reverb for short.

flanger - to actualize an abnormal sound, a delayed arresting is added to the aboriginal arresting with a continuously-variable adjournment (usually abate than 10 ms). This aftereffect is now done electronically appliance DSP, but originally the aftereffect was created by arena the aforementioned recording on two synchronized band players, and again bond the signals together. As continued as the machines were synchronized, the mix would complete more-or-less normal, but if the abettor placed his feel on the border of one of the players (hence "flanger"), that apparatus would apathetic bottomward and its arresting would abatement out-of-phase with its partner, bearing a phasing effect. Once the abettor took his feel off, the amateur would acceleration up until its tachometer was aback in appearance with the master, and as this happened, the phasing aftereffect would arise to accelerate up the abundance spectrum. This phasing active the annals can be performed rhythmically.

phaser - addition way of creating an abnormal sound; the arresting is split, a allocation is filtered with an all-pass clarify to aftermath a phase-shift, and again the unfiltered and filtered signals are mixed. The phaser aftereffect was originally a simpler accomplishing of the flanger aftereffect aback delays were difficult to apparatus with analog equipment. Phasers are generally acclimated to accord a "synthesized" or cyberbanking aftereffect to accustomed sounds, such as animal speech. The articulation of C-3PO from Star Wars was created by demography the actor's articulation and alleviative it with a phaser.

choir - a delayed arresting is added to the aboriginal arresting with a connected delay. The adjournment has to be abbreviate in adjustment not to be perceived as echo, but aloft 5 ms to be audible. If the adjournment is too short, it will berserk baffle with the un-delayed arresting and actualize a flanging effect. Often, the delayed signals will be hardly angle abashed to added realistically aback the aftereffect of assorted voices.

equalization - altered abundance bands are attenuated or additional to aftermath adapted ashen characteristics. Moderate use of equalization (often abbreviated as "EQ") can be acclimated to "fine-tune" the accent affection of a recording; acute use of equalization, such as heavily acid a assertive abundance can actualize added abnormal effects.

clarification - Equalization is a anatomy of filtering. In the accepted sense, abundance ranges can be emphasized or attenuated appliance low-pass, high-pass, band-pass or band-stop filters. Band-pass clarification of articulation can simulate the aftereffect of a blast because telephones use band-pass filters.

overdrive furnishings such as the use of a bottomward box can be acclimated to aftermath adulterated sounds, such as for assuming automatic choir or to simulate adulterated radiotelephone cartage (e.g., the radio babble amid starfighter pilots in the science fiction blur Star Wars). The best basal overdrive aftereffect involves abridgement the arresting aback its complete bulk exceeds a assertive threshold.

angle about-face - agnate to angle correction, this aftereffect accouterment a arresting up or bottomward in pitch. For example, a arresting may be abashed an octave up or down. This is usually activated to the absolute signal, and not to anniversary agenda separately. One appliance of angle alive is angle correction. Here a agreeable arresting is acquainted to the actual angle appliance agenda arresting processing techniques. This aftereffect is all-over in karaoke machines and is generally acclimated to abetment pop singers who sing out of tune. It is additionally acclimated carefully for artful aftereffect in such pop songs as Cher's Believe and Madonna's Die Addition Day.

time addition - the adverse of angle shift, that is, the action of alteration the acceleration of an audio arresting after affecting its pitch.

resonators - accent harmonic abundance agreeable on defined frequencies.

automatic articulation furnishings are acclimated to accomplish an actor's articulation complete like a actinic animal voice.

synthesizer - accomplish artificially about any complete by either assuming accustomed sounds or creating absolutely fresh sounds.

accentuation - to change the abundance or amplitude of a carrier arresting in affiliation to a predefined signal. Ring modulation, additionally accepted as amplitude modulation, is an aftereffect fabricated acclaimed by Doctor Who's Daleks and frequently acclimated throughout sci-fi.

compression - the abridgement of the activating ambit of a complete to abstain accidental aberration in the dynamics. Level compression is not to be abashed with audio abstracts compression, area the bulk of abstracts is bargain after affecting the amplitude of the complete it represents.

3D audio furnishings - abode sounds alfresco the stereo basis

about-face answer - a abscess aftereffect created by abandoning an audio arresting and recording answer and/or adjournment whilst the arresting runs in reverse. Aback played aback advanced the aftermost echos are heard afore the accomplished complete creating a blitz like cool above-mentioned and during playback.2
