## What is Nebulizer?

It would be nice if that echo box worked properly, instead of stretching and warping like this. Maybe you shouldn't have dropped it in the bathtub. We're not looking to place blame or anything, but, you know. Butterfingers.

Anyway.

Apply Nebulizer to live audio input or connect with other music apps such as GarageBand, Auria and Cubasis via Inter-App Audio or Audiobus. Nebulizer supports Audiobus state saving, IAA transport controls, MIDI learn and iOS 9+ multitasking in both split screen and slide-over modes.

Note that Nebulizer does *not* provide an Audio Unit extension. Porting the underlying tech to the AUv3 environment is sadly not practical. I know this is disappointing, but Nebulizer and its sibling apps are stuck in their historical moment; when IAA goes away, so will they. Perhaps something else will come along to take their place...

## Key features

- Live audio input processing
- Inter-App Audio integration

### 5/5 — Just awesome even as IAA in AUM on 12-24-22

*2022-12-25*

Get them all

Any chance of AUv3?

### 5/5 — Auv3 please!

*2020-05-20*

I love your apps and have been using them for years. I will continue to use them, but it would be so awesome if they were AUV3. Thanks!!!

### 5/5 — Thanks!

*2020-02-23*

Another great Matthew Caldwell creation

### 3/5 — Au please!

*2018-02-05, version 1.1.1*

Great plugin. Would love AU for this in multiple instance...

### 5/5 — What are you waiting for?

*2017-09-08*

To the Dev: you may not know it but you're making a lot of musicians' lives better - noticeably - every time they fire up their host DAW and one of your free plugs is there to make their tracks better - noticeably.

### 5/5 — Surprisingly versatile

*2017-09-07*

Surprisingly versatile, from dubby drums to SF horror texture

### 5/5 — What a Thing

*2017-09-03*

Not gonna say what it does 'cause it's free so you can try it. 

I'm not sure why no one else has come up with effect apps quite like these, but the fact that they are unique AND free is pretty nice.

### 5/5 — Interesting but far far too much latency

*2017-06-21, version 1.0.1*

Far too much latency to make it viable IAA effect

### 5/5 — Subtle brilliance

*2017-01-12, version 1.0.1*

I've seen the light. This is a wonderful addition to the library of any sonic dabbler. Just be aware that it doesn't play nicely with other FX under AudioBus. Unless you use separate lanes. I also route it via MiMix.

Nic

### 5/5 — And it's free!

*2016-11-20*

This is where the weird go pro.

### 1.1.2 — 2020-02-07

### 1.1.1 — 2017-09-07

Fixed crash when returning to host application via inter-app audio transport controls.

### 1.1 — 2017-09-03

Updated to Audiobus 3, Midibus 1.39 and current Apple toolkits.

### 1.0.1 — 2016-01-11

Fixed Virtual MIDI configuration so that other apps will identify Nebulizer as a MIDI target rather than a source.

### 1.0 — 2015-12-15

No release notes.
