Sonnox Vocal Thickening and Widening Plugin (Review & Giveaway)

Hello, lovely people. I hope you’re doing marvelously well. As ever, please subscribe, hit the notification bell, and get notified when we put out a new video.

So, there’s a company called Sonnox, and they have a vocal thickening and a vocal widening plugin. I thought, “What better to try would be those two,” because you know, one of our more successful videos both in Pro Tools and Studio One, I believe we have a Logic version and Cubase version — put it this way, we have various versions of it out there.

I thought, “Well, what better than trying out this plugin to see if it can emulate and do the same thing?”

So I’m very excited. There’s two of them. So let’s have a quick look. I’m just going to open them up and have a quick poke around here. So Sonnox, here we go. VoxD Thicken. I haven’t even opened these up before, so this is like, new to me.

Okay, so here’s the Thicken. Okay. And it’s also got a stereo — ah, so no stereo spread on this one. Alright. Let’s go to… Sonnox down here, and we’ve go the mono/stereo. Ah-ha. So I suppose, for me, I don’t know if I would put these directly on there.

Okay, so this has a width control here. So Vox Doubler with a width as well. Timing, pitch, depth, tone. Pretty straightforward. Let’s do this. Let’s create a separate — let’s create a mono auxiliary, and a stereo auxiliary. Put them to solo safe. Let’s open up the Sonnox vocal thickening in mono, and then that’s also a widening plugin.

Okay, so we’ve got them both open here. We’ll name this, “Wide,” and that one as, “Thick.”

Alrighty. So I’m just going to take the vocal, I’m going to turn off all of the other effects.


So that’s a processed vocal. There’s some EQ, there’s some compression on it, but we’ve got no other effects on it.

Okay, so let’s first of all create an input for it. We’ll go for seven on the thickening trick, which is a vox doubler thickener. Okay, so we’ll send from the lead vocal here. Here we go.

[vocals, with effect]

Oh, that’s kind of nice. I don’t know if it — that’s just the default. Ah, now the default went to 50%. I don’t want 50%. I want to make it 100%. The reason why I want it 100% is because it’s not on the vocal itself. If you want to take this plugin and put it right on the vocal, by all means, do. Personally, I don’t do that. I like to have my effects on separate auxiliaries.

Okay, so I’ve got this on. It says you can go in auxiliary mode as well, which would immediately take it to mix. Okay, so you can either set it to auxiliary mode, or set it to 100%. Okay.

[vocals with Thicken]

I like it. It’s — so that’s the default setting. I want to see if I can reduce the timing a little bit.

[vocals, adjusting time]

I like that. So what I’ve done now, I’ve brought it down to 16%. The pitch, as it says, it’s at 25%. So now it’s almost like a little bit of a chorusing.

[vocals with Thick]

Now bear in mind, it’s loud. I think in the track — let’s have a listen.


See, that’s pretty tasty. It’s — look, I’ve taken — I’ve changed two controls, and it already sounds good. Let’s go to pre. So I’m taking my auxiliary send, and I’m making it pre-fade. What does that mean? It means I can mute it and just listen to the effect.

[vocal Thick buss]

It’s kind of fun. Tone is kind of nice. So if you just wanted to use it to thicken underneath like it is, but maybe just try some low end? So let’s have a listen in the track.


Too bright like that, and immediately, all of the t’s and the esses…


That’s horrible. If I click on here using Option, it’s going back to default.



Depth is kind of fun. Okay, so it sounds good. It does sound like a slightly wrong double, which is good.


I actually kind of like — it says too loud there, that’s a nice little indicator. So we’ll bring down the send.

Okay, so what I kind of like about this is I’ve now detuned quite considerably. The timing is a lot closer, so it’s a little bit more like a double. You know, a sung double, but I’m going to bring it down. So I’m going to bring it down a lot.


Take it out. Put it back in. Turn it up. Mute it. Bring it back in. I like that. I like it.

I personally like using a lot of effects on the vocal not very loud. You’ll notice if you watch any of my other vocal thickening tricks, or any of my — you know, using distortion, using octaves, using… I use a lot of different things, but quite quiet, just to kind of add some hair to it. You know, give the vocal a lot of — the Morphoder is a favorite plugin of mine that adds some breadth. There’s lots of good…

But this is really cool, I like this a lot.

Okay, so next up, we’ll use the same send, just because it’s easy. You know what, no we won’t. We’ll use a stereo send on 9 and 10, because it’s a stereo plugin. Alright. So 9 and 10. Interesting. We’ll go to 21 and 22. Maybe put this at 21 and 22. Alright.

So sending to that.

[vocals with effect]

Go into auxiliary mode. Pre. I like that. This is something I might use on a chorus to give it some, you know, totally different feel.

[vocals, then full mix]

Like, totally over the top here. I think even brought down, it’d be too much for me, but maybe if I went to that, [imitates guitar] kind of section, like here. Let’s just turn it all down before it. Go to this chorus here.


So bring it down to about here. I like that. A little less. But you see, it’s…


I like that. That’s great. So that’s just a quick and easy. Put it onto auxiliary mode because it’s on an auxiliary, not on a vocal. If you wanted to put it directly on the vocal, not that I do that, but if you did, you’ve got a mix control so you can blend in the effect. You’ve got timing again, you’ve got pitch again, depth, tone, the same basic controls that we have on the vocal thickening here, but we can adjust the width dramatically.


Both together. So pretty tasty idea. I like it. I like it. I particularly like that stereo — that widening.

[vocals with Widen]

That’s nice. I think what I might do, even though I’m compressing and EQing, I would probably, for me send it something even more compressed before hand. Let’s go for something super generic. You know what? Let’s do this. Have a dynamic EQ.


Oh! Oh!

How good is that? Oh, and all bets are off. Oh, all bets are off. What a wonderful tool. Alright, that’s a whole other discussion. Okay. [laughs]

So what do we have? We have a vocal widening and a vocal thickening plugin here, both of which sound absolutely frickin’ awesome, are quick and easy to use, and used subtly in the right position, are going to really help your vocal stand out. Especially like in that chorus.


Here’s a verse. I’ll put in the vocals as well. The vocal effects. That’s great. Really good.

So what’s wonderful about this is not only are they quick and easy to use and sound really good, it’s they’re giving us to give away for free!
