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.
– 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.
