Spectrum Analyzer RTA

Spectrum Analyzer RTA is a measurement app for audio work, not a general music toy, and by our assessment that focus is its main virtue. It shows frequency content in real time, so people checking room sound, speakers, microphones, or a mix can see what their ears only half catch. The useful part is the visual feedback: a fast read on peaks, dips, and rough balance. The trade-off is that this kind of app is only as good as the setup around it, because bad input or a noisy room still gives bad numbers. In practice it asks for attention and some knowledge of what the graph means. It belongs with other audio analysis tools, not with casual listening apps, and the name says the job directly.
