Features:
- Analyze signals coming from the Mac or iOS device’s current audio input device.
- Assign engineering units to your input signals and calibrate external transducers for accurate measurements.
- Assign input channel units and sensitivities for individual USB Audio devices.
- Direct support for Digiducer digital accelerometers and 485B39 USB ICP signal conditioner from The Modal Shop.
- Direct support for miniDSP UMIK-1 measurement microphone and EARS headphone/IEM measurement system.
- Nominal acoustic sensitivities included for iPhone and iPad built-in microphones, voltage sensitivities for headset input (including the Lightning-to-headset adapter included with recent iPhone models)
- Manually switch between available audio input sources.
- Load microphone frequency response data (FRD) and apply frequency response correction (FRC) to FFT-based measurements.
- Manually adjust audio sample rates, even up to 192 kHz, depending on input hardware.
- Save acquired measurement data to CSV, tab-delimited ASCII text, or MAT files.
- Save high-resolution analyzer display images to PDF files.
- Retrieve your data files from your device via Files (iCloud Drive), iTunes File Sharing, or through a web browser on another device. Files may also be opened in other compatible apps (e.g. Mail, Notes, Numbers, Dropbox, etc).

Basic Tools:
- Oscilloscope - Basic oscilloscope and triggering functions.
