## What is Velvet Machine?

Sonic texture generator / blur / non-linear reverb

*** WARNING ***
Velvet Machine is an Audio Unit v3 plugin and requires a compatible host such as GarageBand, AUM, Cubasis, Audiobus etc. The provided standalone app does NOT support the currently deprecated Inter-App Audio.
***
Velvet Machine is a CPU-intensive effect at high settings. A *minimum* of 5th Gen iPad, iPhone 6s or 1st Gen iPhone SE is required to run a single instance at maximum settings. However, shorter times and/or lower densities use much less CPU.
***

Velvet Machine is a unique audio effect based on real-time convolution with enveloped velvet noise. It's designed to:
- Stretch and blur out even short sounds to lengths of up to 10 seconds
- Produce reverb-like textures with flexible volume envelope (including reverse, fading in and out, pulsating etc.)
- Work as a variable density random multi-tap delay (bordering on granular-like sounds)

PDF manual and video demos are available on developer website.

### 5/5 — Amazing Textures and Reverse Reverb!

*2026-01-11*

I love this app, unfortunately I hadn’t used it much because I have so many other effect apps. But I happen to be playing inside AUM, I had a midi Guitar app open, trying to get a good sounding acoustic setting. As I said I have so many Auv3 apps, that are perfect for guitars, that it is habit to go to certain apps that I ALREADY know work well…. But this day I wanted something different… I opened Velvet and that first opening preset made me go…”Wait! What’s this app called?’ I started going through presets, which like so many of us use as a jumping off point to create our own presets, dialing them in to meet a need we have. But with this app, I kept loving each preset. This thing just lights up each note passing through! I found that I had been playing for hours without realizing the time that had passed! Just perfect sound textures, reverse reverbs, and amazing delayed/verbs!  

Don’t pass this app up! If you want a great reverb or looking for thickness to make your “Acoustic Guitar” or maybe you have your electric guitar and want to solo, open this app, and dial in your sound! You will be happy you did!

### 5/5 — Вельвет и Бархат

### 5/5 — Reverb diferente y asombroso

*2024-11-16, version 1.2.0*

Me encanta. Sería genial una actualización!!

### 5/5 — Better than Your Reverb

*2024-04-23*

I don’t care what reverb you’re using.  This is better (or at least as good).  It’s more fun than a reverb because well - you get to draw your envelope and the system for this is epic.  Come one, come all.  Put your spring reverb in the garage where it belongs, call your neighbors, tell them you’re playing their new favorite song.

### 5/5 — Un Reverb que es mejor que un reverb. ¡Es original único!

*2023-04-29, version 1.2.0*

Tiene un sonido extraordinario, es fácil de usar y barato. ¡Justo lo que buscaba! Es “terciopelo”.

### 5/5 — Lush and subtle

*2023-03-23, version 1.2.0*

Why does anyone need another app like this? Because this is not like any other app of its type. Seriously, if what you are looking for is an app that has that special difference, something that can be used on a component of a track to produce a unique texture, then this is the app you are looking for. Fabulous.

### 5/5 — excellent

*2023-03-22*

it sounds like no other: thanks, Yuri!

### 5/5 — 比效果器优美动听

*2022-10-16*

希望能出更有趣效果器

### 5/5 — Unique tool!!!

*2022-02-17*

Some wishes left: Midi in to trigger, vertical lines in the curve editor, to see Bars/Beats/Time, snap to grid and an amp to get back volume in case it became too low.

MUST HAVE ❤️
