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 the calls of different animals (bats, dolphins), measure the frequency response of hi-end audio equipment, ultrasonic sensors or to analyze any imported audio file into a spectrogram context. Generally speaking, the power of Ultrasonic Analyzer is really big.

Ultrasonic sounds – record, visualize and play back in slow motion!!!

- Playback back analysis (just tap on the spectrogram and play)
- Slow motion playback – transpose required octaves down
- PIP (picture-in-picture), allows the simultaneous analysis on the spectrogram chart and Second chart: Octave RTA, Spectrum or Oscilloscope
- Audio input can be supplied via the built-in microphone and an external microphone (via the USB camera adapter or through the iPhone/iPad dock connector – Core Audio compliant devices)
- Sharing charts and audio recordings (through mail, social networks, clipboard)
- Exporting to the iTunes app document folder: audio recordings (wav) and image charts (png)
- Importing from another application or the iTunes app document folder audio files
- Many formats supported for audio file import: wav, caf, aac, mp3
- Automatic conversion from other sampling rates for imported files
- Frequency scale: linear and logarithmic
- Amplitude scale: linear and logarithmic SPL/RMS (dBFS)
- SPL meter weighting: dBZ - linear
- Variable spectrograms length** (depends on set resolution)
- Minimum requirements – iPhone 4s


*For real-time ultrasonic analysis use an external microphone with ultrasonic capabilities through a USB camera adapter, the iPhone/iPad dock connector or import files recorded on an external device.
