I’ve been using Sound Spectrum Pro for a couple months now. It’s basically an app that lets you analyze audio signals in real-time – things like FFT, RTA, sound pressure levels, and more. Pretty solid if you’re into that kind of stuff.
Here’s what you can do: there’s a super fast FFT that gives you crazy frequency resolution, like 0.05Hz. You can also measure stuff like THD+N, RT60, and noise criteria. It’s got a ton of features packed in, but the interface is still pretty friendly and easy to navigate.
Look, if you’re an audio engineer, musician, or just a sound nerd, you’ll probably get a lot of use out of this. It’s not perfect – the calibration can be a bit finicky and the ads can get annoying. But overall it’s a really powerful tool that does the job well. Worth checking out if you need an advanced audio analysis app.
