Sound Spectrum Analysis

But it irritates me that I can’t get the output signal to another output then the internal speaker. If I could get the signal to an external amplifier this app would be much more useful.

Heard an irritating high frequency noise and searched in App store for an app to be able to measure the frequency, and found this one. Extremely simple yet seems very elaborated for people with technical know-how. Result within a few minutes!

I had a similar app on android and was sad to find the iOS versions lacking until I found this one. This was an easy purchase and the free version actually does quite a lot. I mostly just bought it to show appreciation. Other apps have subscription based models which is ridiculous to me. The interface for this is really clean and it’s just what I want when I’m curious about the frequency of sounds around me.

This is a very well set up app. There is a good amount of built in help, with some online help available. Price (one time) is good. App functions well with a lot of customization/adjustments available. Well done guys!!

Annoying paywall to change any setting. And this is formatted for a small screen.

Basic screen is dark and had to read. Functions can't be tested without paying, so I deleted the app.

My only problem is that I cannot easily select the frequency range I want to look at. The pinch adjustment only works to look at higher frequencies, whereas I want the window to be able to be set not just to exclude low frequencies. Perhaps the ability to set the range manually… type in lower limit, type in upper limit. I have not yet tried with various calibration files yet, but when I get an external microphone I will do this and see how well it works. I basically need this app to measure sound sweeps and pink noise from various devices to check flatness of frequency response, and it seem to do ok at this. Price is right, and it has many options that will make most casual users happy.

I’m a novice speaker builder. I had designed some speakers, used WINISD and Vituix CAD to design the box and crossovers and had the speakers hooked up. I had tried to used Room EQ Wizard, but to no luck. I had problems with a calibrated Mic, getting the software to work right etc. So, I needed some tool to measure the speakers and found this. This tool allows the IMM-6 mic and gives me enough to measure the speakers. The support is fantastic, timely and thorough. I can get the data out, screen grab the graph etc. The price is fantastic, and for those that had problems with the tool not giving them enough for free, it’s only a couple bucks. And for what the designer provides, that’s more than fair. For anyone building their first speakers (maybe even more advanced) this is a great tool.

Most of the negative reviews seems to come from the fact that the majority of features are locked behind $3. It would be nice to have that stated in the description, but if you can look past that, it’s a really nice app. The UI can also be a bit difficult to learn, but the app is really accurate from my testing and does everything it promises to do.

I was surprised that it showed pictures that it has a lot of functions but nothing's real. what a shame
