Loops, Samplers and DJ Effects - Basic Sound Synthesis

By David Nebel

If you boost the synthesizer to the place where it clips and removes part of the audio range, then you've pushed the signal of the synthesiser over the limit. In essence, what you've done is created distortion.

A well known effect when utilising on electric guitars. In addition to this, you could produce additional harmonics by distorting signals in the frequency range. You might also hear distortion being referred to as over drive. These results are really not used very much because it produces a disgusting clipping of the signal, but the creative individual can produce a couple of entertaining outcomes.

Phasers could be practiced in a few stages like two, 4,eight,16 or higher. Signal would be very much more effective when the stages increased. Phasing means the signal passes through an all pass filter. When this occur you get highs and lows or peaks and notches inside the frequency spectrum. If it's a moving effect you want, then the LFO has to sweep the comb filter. This puts away the basic phaser sound.

If you turn up the flanging signal too high, it resonates to an impossible level. You can modify flanging by just changing the sweeping delay rate together with the feedback and signal depth. This's simply like the chorus and phaser effects. The flanger is the same as the artificial chorus and phaser techniques. In the beginning, you can create a sweeping effect of the signals as they became out of synchronize with one another. This could only be done by a tiny amount, and its created by decreasing 2 same reel tapes. This's similar in artificial flanging. It consists of multiplying the single and always changing the delay between the signals at the rate of being within milli secs. Once this occurs, it'll sound the same as a jet plane. As the harmonic bumps and dips of the signal're in series with each other, it creates a comb filter effects.

With delay effects, you could apply a couple of very special methods like creating feed back loops, which will constantly run. You can attain this by reversing the delay play back. Delay is likewise addressed as echo and is a very standard effects component in sound synthesis. All its imitating the synthesizers original sound and then playing it various times between the different time spans.

Producing sound in an enomous room will make the sound reverberate

This is identical with reverb when it comes to sound synthesis. It is one of the earliest effects to be applied and was once produced by plates and springs manually. Presently it's created by digital means. Close simulations of room sizes and applying delays is the method practiced today. This creates the illusion of sound hitting the hearing of the hearer, then right after the reverberation effect is heard. - 18780
