About this app

- Wide range of analysis parameter settings
- Real-time display of peak frequencies and amplitudes (up to 10)
- Frequency (horizontal axis) can be switched between logarithmic and linear scales.
- Note name display mode (displays pitch in A to G♯ note names and error (in cents))
- Peak hold function
- Display range can be changed (zoom, scroll) by touch operation

Analysis Parameters
- Highest frequency: Select from 2kHz to 96kHz (The frequency that can be set may vary depending on the device model)
- Minimum frequency: 0.25 Hz, 0.5 Hz, 1.0 Hz, 2.5 Hz, 5 Hz, 10 Hz, 25 Hz, 50 Hz
- Update rate: 45fps, 30fps, 15fps, 5fps, 1fps

This app allows you to increase the maximum frequency up to 96kHz, but please note that the settings above 24kHz are mainly for high-performance microphones, not for built-in microphones of common devices.
(In general devices available on the market today, data in the high frequency range above about 22 kHz is pseudo-created by interpolation processing on the hardware. Normally, the spectrum in this range contains only a faint noise of less than -60 dB, but depending on the model, Larger noises may appear at certain frequencies such as 48 kHz or 96 kHz due to the interpolation process described above.

Just bought this app. Needed to buy as we were using the free version for to long. Really helped in a noise issue we are having with a local factory over the last year. Got the council to do a survey, the output from this app ... perfect match to thier mega expensive calibrated kit. Great app. Suggestion. Peak hold would be nice and log file output. Thanks for a great product. SB United Kingdom

Tried a few of these apps and liked this one best. The display is clear and the label text size is useful. An option to save apex analysis to file would be nice with a user specified recording rate, e.g. 1-10 samples per second.

Excellent App. Screen grab with file ref stamped on it would be nice :)
