## Audio Spectrum Analyzer Pro Reviews in United States

### *---- "Not free anymore and Stopped working"
It was a great app and now it’s not working unless you subscribe! It’s not worth the price since there’s free apps the work similarly.
-- Frantic Frog, 2025-09-20

### **--- "The app used to work"
The app was great before it became unusable. One of my favorite “features” was using the bottom mic like a directional microphone to pin point hums or beeps around me. It had plenty of graphs to choose from even in the free tier. Now when I open the app the graph won’t even show up. This happened after I reinstalled the app due to offloading and since then it hasn’t worked.
-- Michael 111507, 2025-03-25

### ***-- "Audio input"
I would really love to use this app but I can’t because it only accepts mic input. I’d like to have my own audio output be detected and used as audio input. Or at least be able to upload files!
-- Ohmygodidontcareomfg, 2025-02-15

### **--- "All the features are now locked behind a paywall"
This used to be the best spectrum analyzer but now any of the features you need to make this functional are all behind a pricey paywall. They nerfed its functionality to charge for the features that were already there.
-- arzacalan, 2024-09-25

### ****- "Preferred RTA"
As a media technician, I prefer this RTA over an inbuilt mixer’s.
-- BigENCC1701, 2024-09-17

### *---- "Not free"
Requires in-app trial and purchase or subscription. This was a recent change. Was a great app before that.
-- romans5, 2023-05-09

### **--- "Does not work on macbook pro"
It is an ipad app, but I missed that detail before trying... so FYI it will not work on a macbook as you cannot change any settings. The 2 star rating is because there is not an easy way to cancel the trial (bills you about $20) that is required to get it working.
-- whyisthissodifficult23895, 2023-03-19

### *---- "Same App. Not paying again!!"
Is everyone who had paid for the previous version of this app (that stopped working) getting “Purchase Restore”?  Thanks!
-- iused2haterunning, 2023-03-02

### *---- "Trash"
Just trash. Dont spend your money on apps like this. Its not worth your hard earned money.
-- James nickname was taken, 2023-02-25

### ***-- "Functional but flawed"
I’m a little bitter that the previous iteration of Spectrum stopped working with iOS 16 and iPhone 14 models. I paid for both iPhone and iPad versions to use while mixing live performances. This time around, it’s free (for now) and includes the option to change sound measurement metrics from dB reading from negative numbers) to dBA (readings start from 0 and increase in the positive numbers). This also will tell you the nearest key/note that you’re pinpointing with your finger on the screen. It could have been rated higher but there are a couple of flaws. In Spectrograph mode, trying to pinpoint a frequency is near impossible on my 14 Pro. The graph numbers are obscured by the dynamic island. Also, on the other graph types, low frequencies are on the left and high are on the right. Since the spectrograph scrolls from left to right, low frequencies are now on the bottom. When touching the screen to pinpoint a frequency (since I can’t see any numbers under the dynamic island) the frequency does not align with the flowing graph. It would have been nice if the data would align, the graph was visible, and if the graph also included an axis that showed the elapsed time.
