- Selectable FFT size.
- Selectable window function (used in amplitude spectrum calculation)
- Displays the peak level and its frequency of the amplitude spectrum.
- Generates the audio signal (4 types of waveform)
- Generates the noise signal (white noise, pink noise)
[Setting items]

Added a function to select the Bluetooth connection policy.
Select from the following items. (Initial state: None)
- None: No Bluetooth connection is made.
- HFP (Hands-Free): Supports input/output for calls to Bluetooth-connected devices.
Since input data via Bluetooth is processed, the update speed of the waveform display will be slow.
- A2DP (Advanced Audio Distribution): Supports output of advanced audio distribution to Bluetooth-connected devices.
The audio signal/noise signal generated by this app will be played to the output destination connected via Bluetooth.
