Ultrasonic Analyzer is a real-time spectrum, spectrogram, oscilloscope, and octave RTA analyzer for your iPhone or iPad. It provides a visual representation of ultrasounds using a sampling rate of up to 384kHz**. You can listen to transposed ultrasounds* and analyze them in real time. For sounds that are normally inaudible, a slowed-down playback option is also available. Ultrasonic Analyzer can be used to analyze the calls of various animals (e.g., bats, dolphins), measure the frequency response of high-end audio equipment, or evaluate ultrasonic sensors. Additionally, it allows you to analyze short imported audio files within a spectrogram context.
