## What is Sonic Tools SVM?

This is an analyzer for sound, vibration and magnetic field.
As the source code of this is widely published as an open source software on GitHub, you can make custom version of this.
We welcome the users who want us to make customized version of this app.

* Sound (Analyzer [FFT / RTA / Spectrogram], Scope, RMS, Signal Generator)
* Vibration (Analyzer [FFT], Scope, RMS)
* Magnetic field (Scope, RMS)

You can pinch (zoom) and pan (scroll) on measurement screens other than RTA and spectrogram, and pan (band selection) on RTA. You can pause by tapping the measurement screen. Since the measurement time is displayed at the time of pause, it is suitable for leaving as evidence. Please take a screenshot of the screen in the system standard way.

[Application example]
· Record the present situation as quantitative evidence, such as by using recording and use it for the improvement of obstacles.
· Use it for science education.
· Use it along with the sweep generator to improve the acoustic characteristics of the listening room.

Note:
This application has an audio signal oscillation function, and depending on the operation it may generate sound that is harmful to the human body, so please refrain from using things like headphones or headsets. We are not responsible for damage caused by using that equipment.

The resolution of the spectrum analysis of speech is about 11 Hz inherent, however, the actual resolution is in the maximum of 3 Hz by interpolation processing. It is not the accuracy that can be used to tune an instrument. Please use the instrument tuning application for that purpose.

If you can not find the current point by zooming in or scrolling, you can return to the default state that you can see the whole picture by pressing and holding the measurement screen long.

For a good result with Octave RTA, we recommend using Window Function and Fast Latency Mode.

The adjustable range of the FFT/Scope/RMS gain is from -20 dB to 20 dB.
The adjustable range of the SP gain is from 0 dB to 80 dB.
The noise reduction threshold is from -80 dB to 0 dB.

Allows you to output the data of Sound Spectrum, Sound Spectrogram, and every RMS'.
You can use the data files by Files.app on iOS or iTunes File Sharing on Mac.
Please note that the output file of Spectrogram is not small not like other data files.

### 5/5 — The only one that worked (and free!)

*2026-02-06, version 2.1.12*

Thank you so much. Excellent app. I do wish it was easier to figure out how to catch the decimal point in frequency, but either way, literally the best of all of them after trying five or six.

### 1/5 — Don't know how to use it

*2026-01-11, version 2.1.12*

Not intuitive and no instructions. I have no idea how to make it work.

### 5/5 — Je l'adore

*2025-11-02, version 2.1.12*

Cette application est vraiment pratique pour ce lui qui cherche une alternative au produits très dispendieux comme Smaart et pour un homme qui commence dans le domaine des ingénieurs en sono et en FOH !!!

### 5/5 — Amazing

*2025-10-15, version 2.1.12*

In trying to isolate a high-pitched hum in my home, this app helped me find the frequencies using the FFT and wave generator. Great app!

### 5/5 — Wow

*2025-09-04, version 2.1.12*

Franchement wow , très bonne App pour IPhone , sans publicité et fonctionnalités performantes. C’est très bien de voir cette App qui est une exception dans nôtre monde capitaliste commercial. Félicitations pour vôtre beau travail de création ne changer rien. Merci

### 5/5 — Amazing and free!

*2025-08-10, version 2.1.12*

I’ve used this in a variety of live sound environments, and it has been such a helpful tool for quick EQing and room correction. Is there a calibration tool for the mic or is it dependent on the factory calibration of the iPhone’s microphone?

### 1/5 — Abandoned app

*2025-06-12, version 2.1.12*

A major problem is that due to the small size and close placement of the noise playback buttons, I can't easily work with the app. Additionally, there are no indicators next to the buttons to show, for example, if the color changes, so I can tell if my hand is correctly on the intended button and if the noise is playing or not.

Another program that is abandoned and has bugs.

### 5/5 — Amazing app!

*2025-06-12*

This letter of appreciation goes to the amazing Japanese developer who has made this app. I have no real use for this other than I am a curious person who finds such things interesting. I see how professional and warm hearted you are when responding to reviews, it makes me very happy. I wish you health and prosperity in your life. 

Thank you.

**Developer response:** Thank you so much!!

### 5/5 — Very nice

*2025-04-02, version 2.1.12*

It's an amazing piece of software amazing enough that it's completely free and amazing enough that it's easy to use and full of features

### 5/5 — Exactly what I needed

*2025-03-29, version 2.1.12*

This was what I needed and more, with it’s sound spectrometer
