## What is PhaseDelayArray?

PhaseDelayArray is an Audio Unit, or AU, for iOS. This application is simply a container for the Audio Unit and also serves as the documentation for the AU. PhaseDelayArray must be used in some sort of Audio Unit host or DAW application.

PhaseDelayArray is a bit of a strange effect. O.K, so, what is it? PhaseDelayArray has three effect units chained together in an interesting configuration, and one of these units is just a little bit twisted. The first unit consists of a sequential array of vibrating (oscillating) reverberation sections. The oscillations can be tiny or huge. The reverb depth can be tiny or huge. The overall effect can be subtle or HUGE. It can create a wide range of sounds. The second section is a modulation unit. It takes the output of the PhaseDelays and whips it around, or up-and-down or back-and-forth. The final section is a feedback unit with the possibility of a lot of delay (up to 2 seconds). The mix section allows you to tap into all this strangeness in four different places. PhaseDelayArray can be used in mono-to-mono, mono-to-stereo, or stereo-to-stereo settings. Several of the features work best with a stereo output.

## Key features

- Oscillating reverb sections

### 5/5 — Power!

*2025-04-27*

I am in love with this app.  Wonderful strange soundscapes for the adventurous  and bold.  A go to fx for the far out stretches of time.   Thanks!

### 1/5 — Where’s The App?

*2024-08-12*

Spiffy manual but no actual app. I shaved my legs for this?

### 3/5 — I can’t accept

*2023-11-28*

It’s just a lot of words and copyright trademarks I can’t accept too without the button

### 5/5 — It’s great for weird, emerging and receding echoes?

*2022-04-26, version 1.5*

The most useful control button was added in an update a year or so ago, the ‘randomised settings’ button.  It’s below the two shown in the screenshot pics in App Store, not shown in those pics.  The parameters are many and varied, so in order not to need to become an expert on them, that button helps.  One notable addition would be a bpm/sync option?  Just about every delay has this, and it would make a lot of sense here, too, although probably require some ‘standard’ and even non-standard settings, 1/64 up to 2/1 or something?  

That’s my only useful input really, because one method of using delay/echo is to create multiple tracks where instead of making a sequence on one track, then a different one on another, a few brief notes can be input then they just echo forever, or at least a very long time.  To do this requires some kind of feedback loop limiting to stop the inevitable ever-growing signal that I at least get when cascading echo/delay FX, to avoid damage to speakers or ears.  

Once this is in place, with a GarageBand DAW or any DAW, you could experiment with the random feature, or the manual editing, and it opens up another side to ambient music creation solely based in this app.  Of course, the Developer may already have considered this and there could be deeper issues trying to do this in practice, but that’s my 2p/2c worth.

### 5/5 — Nice

*2021-09-01*

Really need you to make more auv3 apps!

### 5/5 — Please make another effect like this

*2021-01-22*

PhaseDelayArray is very psychedelic and i could use some more very unique crazy effects with lots of parameters to tweak. Thanks for your work

### 5/5 — High quality and free

*2020-02-27, version 1.1*

Unique sound. Anyone who enjoys reverb, echo, and phase will find this useful. Thank you for bringing this to iOS neon silicon.

### 4/5 — Sounds Great

*2020-02-25, version 1.1*

Considerably better than 1 Star.
GUI is weird and uninformative but the reverb/delay sounds luscious and evolving.
I like weird and wonderful though.

### 1/5 — Completely fake

*2019-12-06, version 1.1*

Don’t waste your time downloading his app

### 5/5 — Big Thank You!

*2019-10-26, version 1.1*

Big thank you for the developer Neon Silicon for giving us these apps. I was suspicious at first because the apps were free but after testing them it was more than obvious that we were given high quality music apps. My favourite app is PhaseDelayArray
which is very original and stable. Other free apps offered here are equally good.
