Ultrasonic Analyzer

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 listen to transposed ultrasounds* and analyze them in real-time. For sounds normally impossible to hear you can also use slowed-down playback.
Ultrasonic Analyzer can be used to analyze 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.

Features

Sampling rates: 44.1kHz, 48kHz, 96kHz, 192kHz, 200kHz, 250kHz, 384kHz

Recording trigger (triggered by frequencies in the specified frequency band)

Zoom and pan all charts

Measure values in all charts

Playback back analysis (just tap on the spectrogram and play)

Transposition during playback

Slow down 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 iOS Document Browser (supports iCloud): audio recordings (wav) and image charts (png)

Importing audio files from another application or from the iOS Document Browser (supports iCloud)

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)

Tested with (via the USB camera adapter):

Dodotronic Ultramic200K, Ultramic250K, Ultramic384K

Make sure you use the latest iOS update.

Use an external microphone with ultrasonic capabilities through a USB camera adapter or through the iPhone/iPad dock connector.

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.
