4 ★ Cool, it works well for me. Thx
5 ★ A four leaf clover for good luck
2 ★ difficult to handle
5 ★ Best of the lot
3 ★ Best on a tablet. Text is too small to read and buttons too small to tap on smartphone. Data is lost upon rotate landscape/portrait. Not enough exponential averaging between FFT bins. 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.
4 ★ If it has option to DFT the earphones audio it will be damn perfrct
4 ★ Not good app costly creates unwanted sound waves an deep hall vocials like men thyroid glands
5 ★ Maybe next sound project for audio recorder in professional style (TASCAM, ZOOM, ..) ??
4 ★ Frequency and time analysis with a decent variety of basic algorithms.
5 ★ Very Useful, best app of it's kind in the play store.
1 ★ Slow... sluggish... delayed response.... Not good.
5 ★ Lol no Fry
5 ★ Spectrum Analyser.
3 ★ Good
5 ★ 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.
