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. Features - Sampling rates: 44.1kHz, 48kHz, 96kHz, 192kHz, 200kHz, 250kHz, 384kHz** - Real-time transposed ultrasound listening during recording* - Spectrogram analyzer: Color and black & white modes - 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 - dBFS Meter - Fast real-time response - Adjustable spectrogram frequency resolution - Configurable time interval between FFT computations, with values as low as 1ms or even lower - Fast Fourier Transform (FFT) - FFT window sizes: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536 - Recording trigger: Automatically triggers based on specified frequency bands - Zoom and pan capabilities for all charts - Measurement tools available in all charts - Playback analysis - Transposition during playback - Slow-down playback: Transpose octaves down for easier analysis - Picture-in-Picture (PIP) mode: Allows simultaneous spectrogram analysis with a secondary chart (Octave RTA, Spectrum, or Oscilloscope) - Audio input support: Built-in microphone, external microphone (via USB camera adapter or iPhone/iPad dock connector – Core Audio compliant devices) - Sharing options: Share charts and audio recordings via email, social networks, or clipboard - Exporting capabilities: Save audio recordings (WAV) and image charts (PNG) to iOS Document Browser - Audio file import: Load short audio files from other apps or the iOS Document Browser - Supported audio formats: WAV, CAF, AAC, MP3 - Automatic sample rate conversion for imported files - Frequency scale options: Linear and logarithmic - Amplitude scale options: Linear and logarithmic (dBFS) - dBFS Meter weighting: dBZ (linear) - Adjustable spectrogram length (dependent on resolution settings) Tested with (via USB adapter): - Dodotronic Ultramic200K, Ultramic250K, Ultramic384K - Pettersson M500-384 - Avisoft UltraSoundGate 116Un Make sure you are using the latest iOS update. *Requires an external microphone with ultrasonic capabilities connected via a USB adapter. **Real-time analysis at a 96kHz sample rate or higher is only possible with an external USB microphone. Alternatively, you can import files recorded on an external device for non-real-time analysis.
