Ultrasonic Analyzer is a real-time spectrum, spectrogram, oscilloscope and octave RTA analyzer for your iPhone or iPad. It can give you a visual representation of many ultrasounds using a sampling rate up to 384kHz*. You have the opportunity to record, analyze and use slow motion playback for sounds normally impossible to hear. Ultrasonic Analyzer can be used to analyze in a real-time the calls of different animals (bats, dolphins), measure the frequency response of hi-end audio equipment or ultrasonic sensors. You can also analyze any imported audio file into a spectrogram context.

*For real-time ultrasonic analysis use an external microphone with ultrasonic capabilities through a USB camera adapter or through the iPhone/iPad dock connector. You can also import files recorded on an external device.
**Only available on devices with 64 bit processors – iPhone 5S, iPad Air
