## What is The Oscillator?

Simple and elegant tone generator with two Oscillators and one Noise generator, each with individual lowpass filters. The oscillators also has panning, and can produce one of four waveforms: sine, triangle, sawtooth and square.

The oscillator frequencies can be tuned precisely in Hz or fractional MIDI note pitch.

Use it for testing purposes or to make old-school electronic drone music.

Supports Audiobus and Inter-App Audio: Stream the audio output in real time into other compatible apps!

## Key features

- Two oscillators
- One noise generator
- Individual lowpass filters
- Panning control
- Four waveforms (sine, triangle, sawtooth, square)
- Precise frequency tuning (Hz/MIDI)
- Audiobus and Inter-App Audio support

### 1/5 — Naja

*2026-05-18*

Ich verstehe den Sinn dahinter aber was es erzeugen soll aber sie müssten noch viel mehr Funktionen haben wie zbs das man die Wellen kürzen kann das man ein guten Bass hat um es dann auf 16 Buttons zu legen. Dann noch mehrere Ebenen wo die gleichzeitig die Töne abspielen kannst etc. Ich glaube man versteht mein Ansatz aber ist wahrscheinlich schon Tod die App

### 5/5 — Love it

*2025-10-25*

Use it to create simple binaural tones and white noise to sleep. Also gives relief for tinnitus. Used it to test specific hearing loss frequencies. Truly useful free app.

### 4/5 — Peut faire mieux

*2023-08-31*

Volontairement très basique, donc très incomplet. 
Mais intéressant pour l’expérimentation 
(par exemple : pour entendre précisément l’effet des battements entre fréquences sonores exactes). 
 
Ce qui est dommage, c’est qu’on ne peut pas cliquer sur l’affichage des valeurs de fréquences pour y entrer directement un nombre.

### 1/5 — Stopped working properly. Only noise comes out. Loved it originally.

*2023-07-06, version 1.3.3*

Not working.

### 4/5 — auv3 please

*2023-03-05*

we need this on auv3

### 5/5 — Exactly What I Needed

*2022-10-28*

Back in the early 90’s… I use to use 100% hardware to DJ in our clubs. Fast forward to today and the entire landscape has changed. While we were concerned with beat matching, it was more of an Ear Game. Our one and only CD player collected dust before anyone would touch it. As I get deeper into DAWs, I’m not understanding all the terminology and what it means. This app has been an incredible help when it comes to the different structures. I can finally understand what I’m doing in this area.

### 5/5 — Typical Kymatica!

*2022-05-02, version 1.3.3*

Sounds great! Works great!

### 4/5 — oscillator: simple & good tool

*2021-07-13*

i like simplicity of oscillator & it does exactly what it says. trying to understand synth-like interaction of the (3) channels, oscillators A&B and 1 noise generator. only thing i would add is something about how 3 channels interact but that would complicate it. so oscillator excellent as-is.

### 5/5 — 👍👍👍

☝️😈

### 5/5 — Best tone generator for testing audio equipment

*2020-06-26*

I am using several tone generator apps to test a home built valve guitar amplifier. After trying several, this one is by far the best. Here’s why:

1. Log scale frequency sliders. This is so important.  Down near 20 Hz, a difference of 1 hz is a big difference and you need precision of less than one Hz. Up above 2000 Hz a 1Hz difference is not very significant and you need to sweep quickly. That’s why a tone generator must have log scale frequency. Most tone gen apps don’t have it but this one does. 

2. dB scale gain. Similar to the log scale frequency, if you don’t have dB scale volume control then you really can’t control the volume at the low end. This app has it. 

3. More than one oscillator. If you are testing an amplifier you may want to see how it responds to a combination of a low and high frequency tone. This app does that. Most others do not.
