If it has option to DFT the earphones audio it will be damn perfrct
Frequency and time analysis with a decent variety of basic algorithms.
Great features, but text is too small to read and buttons too small to tap on smartphone. Would be better on tablet. No way to calibrate app with cal file, but you can export data as CSV file and then do your own calibration vs known calibration mic in a spreadsheet.
The best one I've seen After reviewing half a dozen of the top rated free spec analyzers, this is the best by far. To the morons who gave this one star, you neither understand nor have a use for this type of app so keep your opinions to yourself.
UNBELIEVABLE AMAZING APP! This is an amazing, instructive, flexible, technically advanced and thoroughly well designed app. I could spent hours without end just using it. The only regret I may have is that perhaps my Samsung Duos display is a little bit small for doing justice to all the settings and capabilities of this app. A five Star indeed, one of the best ever!
Awesome app! Can't believe it's free & ad-free Only additions I'd like to see are a calibration utility for stock mics, and an external mic option with same calibration ability. I'd pay for those in a heartbeat. Bad reviews for crashing: sorta OK, device may not be powerful enough to run full steam. Bad reviews for "not what I expected(what the hell did think when you dl'd an FFT app!?!)" "Too complicated(again, see above)" you just dl'd lab grade SW for FREE!! Wish it had external input/cal options for vibes like in/s², in/s, in, for accelerometers.
