Pedalutze...

[Guest SyNerZ]

Intrebarea mea e ce fac exact pedalele...adik cu ce skimba sunetul...distors si overdrive stiu...dar in schimb Chorus, Delay, Compressor, Reverb, Tremolo....astea sunt chestii pe care nu le stiu;))...dak ati putea incerca sa explicati in termeni mai simpluti<mai pt tot prostu >....

Intra aici (la sectiunea Compact Pedal Test Drive) si ai foarte multe exemple. (nu vreau sa fac reclama, dar chiar mi'a placut modelul de prezentare a pedalelor BOSS).

Chorus, reverb, delay fac in teorie acelasi lucru, iau semnalul original si il repeta, decalat cu un anumit timp T.

Acest timp T, determina in principiu ce efect e (in fc si de alte lucruri aplicate)

Chorus: (din cate retin, timpul T trebuie sa fie sub 10 ms) da impresia ca sunt mai multe chitari cantate simultan.

Reverb: ( T este intre 10 - 30ms) imita reverberatiile produse intr-o anumita incita, sunetul este repetat destul de repede incat sa nu se distinga diferenta intre el si reflectia lui, dar destul de lent cat sa nu semene cu un cor (in caz ca nu stiai, un sunet emis se va reflecta de suprafetele intalnite si se va intoarce, decalat; acest lucru se numeste reverberatie)

Delay: (T este peste 30ms), in principiu, seamana cu un ecou, in fc de acel T.

 

 

(la chorus de obicei se aplica detune si/sau phase shift, pe langa acel decalaj, la reverb de obicei se aplica mai multe filtre, printre care comb si allpass, nu intru in detalii)

 

 

Cat despre tremolo, imagineaza-ti ca ai sta cu degetul pe volum si ai invarti destul de repede de la 0 la 100% volumul.

PS: rog corectare in privinta acelor T

Chorus splits your guitar's signal in two, modulating the second signal's pitch and mixing back in with the "dry" original signal. The effect sounds like several guitarists playing the same thing at the same time, resulting in a wide swelling sound.

A Delay or Echo pedal creates a copy of an incoming sound and slightly time-delays it, creating either a "slap" (single repetition) or an echo (multiple repetitions) effect. Delay pedals may use either analog or digital technology. Analog delays often are less flexible and not as "perfect" sounding as digital delays, but some guitarists argue that analog effects produce "warmer" tones. Early delay devices actually used magnetic tape to produce the time delay effect.

Reverb is the persistence of sound in a particular space after the original sound is removed. When sound is produced in a space, a large number of echoes build up and then slowly decay as the sound is absorbed by the walls and air, creating reverberation, or reverb. A plate reverb system uses an electromechanical transducer, similar to the driver in a loudspeaker, to create vibration in a plate of sheet metal. A pickup captures the vibrations as they bounce across the plate, and the result is output as an audio signal. A spring reverb system uses a transducer at one end of a spring and a pickup at the other, similar to those used in plate reverbs, to create and capture vibrations within a metal spring. Guitar amplifiers frequently incorporate spring reverbs due to their compact construction. Spring reverberators were once widely used in semi-professional recording due to their modest cost and small size. Due to quality problems and improved digital reverb units, spring reverberators are declining rapidly in use. Digital reverb units use various signal processing algorithms in order to create the reverb effect. Since reverberation is essentially caused by a very large number of echoes, simple DSPs use multiple feedback delay circuits to create a large, decaying series of echoes that die out over time.

Sper ca nu voi fi acuzat de reclama... oricum nu sunt dealer.

Aici se pot downloada si auzi cam ce inseamna chorus, flanger, echo, delay.

Mai degraba sa auda (o ureche fina face diferenta) decit sa se chinuie cu teoria.

Multumesc mult atat lui Dreamchild si lui Razvanciub8a, cat si celorlalti, cu toate k termenii folositi nu sunt exact "pt tot prostu" ...

Am incercat sa zic si ce se intampla cu adevarat, si cum suna (probabil ceea ce te interesa pe tine).

[Guest SyNerZ]

Si iti sunt recunoscator....nu era un repros ieftin;))....
