About this app

This app performs simple frequency analysis (FFT) in real time during sound recording and playback.
The sample frequency can be precisely set from 8000 Hz to 192000 Hz.
The sample bit length can be set to 8, 16, or 32 bits.
The display refresh interval can also be set from 0.1 to 1.0 seconds in 0.1 second increments.

Parameters such as recording/playback and FFT display interval may not be handled correctly depending on the capabilities of the device.
