- 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 and output 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).

Very powerful. Very diffiicult to learm

The instructions are written for somone who already knows how to use the program. This is typical for programmers. Can't scale the vertical units as I would like and had to learn how to translate their units into volts. For them, m means volts, micro (greek symbol) means millivolts, and n means microvolts. This will drive you crazy. Can't set the peak of the fundamental to 0 dB. For instance, 1 volt p-p reads as -60 dB. Won't give TDH totals. Maybe there are ways to do these things but can't find out how in the instructions.

The program is buggy and tends to lockup. Needs to be restarted. It needs more work. Also typical. The older verson was much easier to use. This is just too hard to use. Finally geting the hang of it but doubt I can reach its full potential because of the lack of good instructions.
