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. ## Ultrasonic Analyzer Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/4f/e7/74/4fe77470-7b12-fc5a-8bbb-492b6eb8939b/screen1.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/b5/87/d5/b587d572-a62d-5544-bb18-71ea7bc1d6ac/screen2.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/79/1d/5d/791d5de6-f14d-2126-55ad-a2f86ad71fc8/screen3.png/1320x2868.png) ## Ultrasonic Analyzer Rating Breakdown in United States - 5 stars: 22 (63%) - 4 stars: 3 (9%) - 3 stars: 2 (6%) - 2 stars: 1 (3%) - 1 stars: 7 (20%) ## Ultrasonic Analyzer Reviews in United States ### *---- "$20 for *this*?" This app is pretty amateurish, not even supporting Bluetooth headphones on iPhone. It's 2025. When was the last time you saw an app that could only output over wired headphones? I didn't realize that was even a possibility. It's like the developer stopped trying back around 2018, and never updated it further. The app's readouts also mix dB (SPL) and dBFS freely, even though there is no way to get SPL without first calibrating the system. What's up with that? The whole thing just feels very "beta version written by a student in their dorm room." This is the single most expensive single-purchase app I have ever encountered. I probably wouldn't bother to keep it even if it were free. -- AOANLA, 2025-01-02 ### ***** "Counter surveillance uses" Anybody who’s the victim of any kind of surveillance abuse or voyeuristic abuse in general, can use this app to pick up on a nearly imperceptible frequency around 14,000 kHz. The untrained ear you wouldn’t be able to hear this frequency but it is the result of using wave generated surveillance systems such as the CTX 4000 or the national security agencies tempest program that uses subtle amounts of non-ionizing radiation directed at the building that the target is in to pick up on all the electronic and more importantly biometric information similar to what you get from the xavor1000 system. Simply run the recording through a program like audacity or adobe audition and increase the decibel rate what’s you hone in on it with the apps spectrum analyzer. -- Setnom80, 2024-09-05 ### **--- "No Instructions" Trying to capture my neighbor blasting us with ultrasonic sound but there are no instructions with this app on how to utilize this. -- HOLLA.!, 2023-03-20 ### *---- "No ultrasound" Great app, one problem, Apple audio doesn’t go above 22kc. Have a solution let me know. -- devth, 2022-03-26 ### ***-- "🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨" This is the best analyzer on the App Store but please Update it -- Greg.ni, 2021-10-07 ### ***** "Works well, great UI, helped me eliminate a cause of a problem" How can the microphone on an iphone sample at such absurdly high rates? I don't know, but it seems to work, and this app has helped me eliminate ultrasound pollution as a cause of headaches that my wife's Macbook air m1 is causing us. The UI is FANTASTIC. The author clearly knows a thing or two about UI design! -- lamenick67, 2021-07-27 ### ***** "Works great!" I’m using an iPad Pro with a USB to lightning adapter to interface with a Dodotronic Ultramic 384BLE. I saved for a long time to purchase the Ultramic so I could listen to the bats that fly around my house. I love this setup! -- Scott Loflin, 2020-09-03 ### ****- "Great app" Love this app for analyzing bird calls. Can’t seem to play through Air Pods though. -- Warblerman, 2020-04-19 ### *---- "Cannot export audio files" Cannot export audio files Cannot save audio files Play button does not work No presets for quick investigating. -- srtup, 2019-12-11 ### *---- "Buggy, Unreliable, Poor Interface" We were told to install this device for work. It is a very average app for a premium price. It crashes all the time and does not recover the previous audio file. The tool itself is fine, but that doesn't matter when the risk of data loss is so high. Interface is mediocre. I’d recommend the developers go back to the drawing board on this one. -- Pecan Sandy, 2019-04-24 [View all Ultrasonic Analyzer reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Ultrasonic Analyzer Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Australia | Music | #118 | | Top Paid | United Kingdom | Music | #202 | ## Apps Similar to Ultrasonic Analyzer -
