Filtro y efectos de delay

El sonido grabado puede modificarse usando herramientas que efectúan cambios en la calidad real del sonido. Esta semana veremos la ecualización y el delay, y estudiaremos los diversos efectos de sonido que se derivan de estos dispositivos.

As we talk about these filter and delay devices, it's important to understand the

basic fundamental building block. In fact, they're all kind of crafted

around this one kind of module with just a few parameters but it's really

important to understand it because it all builds from this.

It's kind of the delay building block. And it includes delay time.

That's the amount of time from the input to the output.

It includes [INAUDIBLE] a dry/wet, which is a mixture of the wet signal, and wet's

kind of a funny term, but the wet is the delayed signal, and the dry is the

undelayed signal. And the feedback, which is how much the

wet signal is routed back to itself. In this video, we are just going to look

at the basic delay concept, get a feel for those controls.

And then we'll move into the larger plugins and larger effects that are built

from this basic building block. In this demonstration, input will be on

the left, output will be on the right. Input will always be in green.

Output will be in red. There's a diagram in the bottom which

shows input and output clearly. The signal enters from the left and is

split into two halves. The top half is known as the wet part and

the bottom half is known as the dry. Wet in any delayed context just means the

delayed signal, and the dry is the undelayed signal.

On the wet side of this diagram, we see the delay unit, and the delay unit really

just holds on to sound and then releases it a little bit later.

We have delay time, which controls how much the delay unit waits before it

releases that sound. The dry/wet control at the end allows us

to blend between the dry undelayed signal, and the west delayed signal.

And the feedback control routes the delayed signal back to its input, so that

the delays can repeat over time. Throughout this video, I'll be using a

simple sound. Let's hear it.

[SOUND]. In the display, we're seeing the green

and red trace are exactly the same. The input is the same as the output,

which will always be the case when your dry/wet balance is set all the way to the

dry side, which means that input Is output we're only hearing the dry side of

this path. If we turn that dry/wet balance all the

way to the wet side, we'll hear only the wet.

I'm also increasing delay time a bit. Let's hear it.

[SOUND] This time, you only heard the second delayed signal.

The green is the input, but since the dry/wet balance is all the way to the wet

side, we're only hearing the delay of the output, and none of the dry path.

We're only hearing the wet path. We can mix both the dry and wet together

in any proportion. If I set it in the middle, we'll hear

both the dry and wet side at the output of the delay block.

[SOUND] The output includes the original dry but it also includes the delayed

signal. Typically, we put the dry/wet toward the

left, so that the delayed signal is quieter than the input drive.

[SOUND] That helps the listener to differentiate, which is the original

signal and which is the delay. But we can also do some unusual things.

If I was to turn the dry/wet balance very high.

We might get a situation where the wet delayed signal is actually louder than

the input dry signal We also have a feedback control, which routs some of the

output of the delay block back to the input of the delay block.

The feedback control is only a gain stage.

It's increasing the level of the signal going back to the input of the delay.

If you put feedback to high the sound will continue on forever and if you put

it down low the delays will fade away quickly.

Let's see the effect of feedback. [SOUND] Now, we get a series of repeats.

If I lowered the delay time down, those repeats will be closer together.

[SOUND] If I increase speed back [SOUND] those series of delays will continue on

for a very long time. That really is the basic functionality of

a delay device. This knowledge will translate to all of

the other delay devices that are built from this block.

Courses, phasers, flangers, short delays, long delays, reverbs, and even our filter

devices are built from this simple block.
