## What is Audio Analyzer?

The analyzed result of the waveform is rendered at 60FPS.
The following 4 functions can be accessed:

Waveform visualizer (oscilloscope)
Spectrum analyzer
Historical peak
Historical FFT

Tapping each function enters into full-screen mode and tapping once more exits full-screen mode.

Horizontal zoom is only available for the spectrum analyzer.
Magnification gesture (aka pinching) allows for zooming in and out, and frequency offset can be performed by swiping on the screen horizontally.

Vertical swiping adjusts input volume.
Coefficients are displayed in the corner.

this app wont work on my first gen ipad pro, it is awsome on my i phone 13 mini though. 
is it for i phone only?

**Developer response:** No we can’t provide them.
It’s an os requirement.excuse me.

### 5/5 — 🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨

*2021-10-08*

This app is soooo good…. THANKS 👍🏼👍🏼

### 4/5 — Simple & Complete

*2020-01-16*

I quite like this app, the developer did a good job.

I would have given a 5 stars if this app had the following features:
- the ability to stabilise the signal on the waveform part (like an oscilloscope - maybe just have a switch to toggle the oscilloscope function on/off)
- ability to choose the source (microphone/input source)

But as I said, this is already pretty good and I would gladly pay for an app like this.

**Developer response:** Thank you review.
I want to be able to implement the functionality.

### 5/5 — Don’t know how to use it yet

*2019-11-03*

Please add English help for users

**Developer response:** I have created a how to view. It is described in English and Japanese, but each language is same sentence.
Please feel free to ask anymore.
