Sound Spectrum Analysis for Android

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

What a hack. BIG mouthful of promises what this app all could do. But this is just ahoax. In reality, at least until you may consider spending $$$$, you get nothing. No frequency analysis, 90% of the functions are not present and constantly you get bugged for money. Don’t waste your time, with is Fraud.

Hi, I was quite happy with this app. But some crucial request should be asked for my application. I am using a high quality microphone sampling rate is up to 192 kHz. I was quite happy this app showed the spectrum range up to 90KHz, but the actual measurements was roughly quadrupled, maybe because it only assumed 22kHz as maximum frequency. I need an update to match with the actual spectrum. Thanks in advance
