iZotope Trash 2 Basic WaveshapingMusic ProductionSound DesignBerklee Online

[MUSIC PLAYING] In this movie, we're going to
have a look at Trash 2 by iZotope, and look at its wave shaping
distortion capabilities. So I have Trash 2 here
inserted on a track. I've got just a drum
beat happening right now. [DRUM BEAT PLAYING] And it's a good sound
source for trying to work through how this
plug-in makes distortion and explore some of its features.

It's a way of shaping
distortion plug-in. What's nice about this one, is that
this is the actual wave shaper. And we can actually manipulate it,
and make our own wave shaping curves. So we have a lot of control over the
actual kind of distortion we make.

So I have a number of
modules here in Trash, and they're all shut off right now
except for the actual trash module, which is where I have the wave shaper. There are two different
wave shapes here. I can have two stages of distortion,
and stage two was turned off right now. So I'm just working
with this wave shaper.

There's also a filter, just a high
and low filter after the distortion. And again, for now I
have this turned off. So pretty simple setup here. This is the wave shaper,
and it's currently a symmetrical distortion set up.

What I have here is the
ability to change the wave shaper in this quadrant,
and then whatever changes I make to this quadrant, this
is the positive amplitudes input versus output,
I'll see the same change applied to this quadrant, negative
amplitudes input versus output. So here I just have simply a unity gain
function here, it's just my drumbeat. [DRUM BEAT PLAYING] But then I can apply a little bit
of a wave shaping distortion here. So now these are the input
versus the output values here, and they've been changed a little bit.

Some of these lower amplitudes are
now a little higher at the output. Little bit of very gentle distortion. [DRUM BEAT PLAYING] Mostly just a little louder. And then I can take the peak amplitude
and take it down a little bit.

And again, notice that
whatever I do to this quadrant, I get the mirror image in this quadrant
here, it's symmetrical distortion. [DRUM BEAT PLAYING] I can add a point here,
just double clicking. If I want to, I can
option click to remove it. Or click here to remove it.

I'm going to add another point. And I'm going to change the
way shaping a little bit. [DRUM BEAT PLAYING] Here's the original. [DRUM BEAT PLAYING] Especially the kick drum,
I can hear there's almost like a gated kind of effect.

Now I'm going to go the other way. But this is where you
have to be careful, because I'm taking these low
level amplitudes at the input, and I'm making them much
louder at the output. So this is where we're going
to get some crunchiness. [DRUM BEAT PLAYING] This is where you want to be a
little careful as you explore.

Now if I wish I could see this
curve a little more closely, I can here in the zoom. I can just click on
this quadrant, and I'll see just this quadrant zoomed up close. And I know this quadrant is
going to give me the same curve, because it's a symmetrical
distortion set up. [DRUM BEAT PLAYING] I'm going to delete this
here, just option click.

Now this connection between these two
points, is determined by this setting here. I currently have tension,
which is how I can change the actual shape of this curve. [DRUM BEAT PLAYING] I can have it do other things as well. For example, I can have
just a linear connection.

So there's no more of
an exponential kind of curve, but simply a line to this
point, and then a line to this point. [DRUM BEAT PLAYING] And if I add more points,
I have linear connections. [DRUM BEAT PLAYING] I want to clear all of this
just by clicking on Clear All. I can also have the connection be made
with a bunch of squared functions here.

Now I have to be very careful. This is going to be very loud. So I'm going to come over
here, turn the gain down. [DRUM BEAT PLAYING] That's pretty radical.

You can see in both
quadrants what's happening. From here, I can turn down the maximum
peaks here of all of these squares. [DRUM BEAT PLAYING] And if I get that little point in
the middle here and pull up or down, I can actually change the
density of the squares. And so, now I have almost like
a gated kind of effect here.

[DRUM BEAT PLAYING] Because so many of these amplitudes at
the input map to zero at the output. Although I can move them off zero
line, and now they're all going to get mapped to something other than zero. [DRUM BEAT PLAYING] Like that. I'm going to clear it again.

Instead of squares,
I can have triangles. I can have sine functions. Or kind of a stairstepping here. This is going to be almost
like quantization here.

[DRUM BEAT PLAYING] And go ahead and decrease
the number of steps. [DRUM BEAT PLAYING] Increase it. [DRUM BEAT PLAYING] And move them off of zero. [DRUM BEAT PLAYING] Which gets pretty loud.

Or even exchange positive values
for negative values at the output. So a polarity change for
just the lower amplitudes. [DRUM BEAT PLAYING] Creating quite a lot of distortion. And of course, with the mix control,
I can blend it with the original.

[DRUM BEAT PLAYING] This is the basic idea
with a wave shaper. And here, now I get to actually
play with and control the shape of the wave shaping distortion. [MUSIC PLAYING].
