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 - Listening to transposed ultrasounds during recording feature* - Spectrogram analyzer (color, black and white) - Spectrum analyzer - Oscilloscope (full FFT window size) - Octave RTA analyzer: bands - full, 1/3, 1/6, 1/12 (RMS values) - Max/min Octave RTA values - SPL Meter (dBFS) - Fast real-time response - Variable frequency resolution of the spectrogram - Variable between FFT computations time interval (available smaller than 1ms!) - Fast Fourier Transform (FFT) - Window sizes: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536 - 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 - Pettersson M500-384 - Avisoft-UltraSoundGate 116Un 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.
