## What is Noise Synth?

‘Noise Synth’ is an interactive sound application for iOS developed by Mamoru Ichikawa (Interactive Artist). This application generates sounds from random noise by Fast Fourier Transform (FFT) technology. ‘Noise Synth’ supports 3 types of noise source (white, pink and red noise), 44.1kHz sampling rate, 48Hz frequency resolution and 512 band frequency filter. 

 By touching the filter graph everyone can generate various sounds easily and intuitively from noise like painting a picture. The filter graph values can be increased or decreased automatically, and additionally by tilting the iPhone/iPad everyone can shift or rotate the filter value and frequency through the internal accelerometer sensor. Such an operation enables inexperienced sound generation from noise like a new music synthesizer.

## Key features

- Generates sound from random noise

### 5/5 — Great but . . . .

*2023-02-27, version 1.0*

Great instrument but needs to be audiobus compatible.

### 1/5 — Terrible app & they want $7.99!

*2022-10-28, version 1.0*

So what? This is really poor. It only supports left-hand landscape orientation. Seriously? And so what? You use your finger to turn on the noise but so what? Then to want $7.99? Hardly. There’s nothing here and nothing to love.

### 5/5 — Super cool!

*2022-08-30, version 1.0*

And lots of fun 🙂

### 5/5 — Good

*2020-08-30, version 1.0*

I am no noise music artist but I can see the appeal of this app

### 5/5 — 面白い〜

*2020-01-14, version 1.0*

まだ曲に組み込んだりはしてないけど、いじってみていい感じだった。いかにもノイズみたいな音も出るし、エフェクトみたいに綺麗な音も出せる。楽しい。

### 4/5 — Fantastic little noise app.

*2018-05-28, version 1.0*

This is a very hidden gem.  It’s one of my favorite apps to play with for generating ambient noise.  The only thing that prevents this app from being a perfect five star app is that it doesn’t have audiobus support (To the developer: Please add audiobus support to this app!  It would make it perfect!).

### 4/5 — ノイズ生成アプリ

*2016-06-29, version 1.0*

音楽制作の幅が広がります。

現代音楽系の音楽作ってる人向けのアプリです。

### 5/5 — Great for noise artists!!

*2016-06-23, version 1.0*

Love this app. Very creative and intuitive way to use noise in musical ways.

## Frequently asked questions about Noise Synth

### What kind of sounds can Noise Synth create?

Noise Synth generates unique sounds by processing random noise (white, pink, or red) through a Fast Fourier Transform (FFT) engine. Users can shape these sounds intuitively by interacting with a filter graph, allowing for a wide range of experimental audio.

### How do I control the sound in Noise Synth?

You can control the sound by touching the filter graph to adjust frequency and amplitude, similar to painting. Additionally, tilting your iPhone or iPod can shift or rotate filter values and frequencies, offering a dynamic way to manipulate the audio output.
