Includes REAL TIME scanning of audio signal from internal or external microphone. *** OUTPUT *** Visualization is done on real like device that shows: - Audio level - Noise Level - Frequency range - Current frequency - Frequency oscilloscope - Spectrum analyzer *** ACCURACY *** Application is calibrated with real tone generator. Working range is around 15 - 22500 Hz, and accuracy around +/- 0.5 %. *** NOISE LIMIT *** You can easily set a limit that removes noise treshold with included trackbar. *** RANGE SELECTION *** Choose minimum and maximum frequency you want to scan. *** EXPORT *** You can export output chart to comma-separated file that you can later analyze with MS Excel or other table processor. Application shares document folder in iTunes. *** SUPPORT*** Please don't hesitate to write us for details or questions: lubomir.havran@gmail.com
