App Description

This is an App that decodes Morse code input from the microphone.
It is a Morse practice App that you can use to check if you are keying the correct code.
Signals with good S/N can be decoded correctly, but signals with bad S/N cannot be decoded correctly.
Also, the performance will be degraded for extremely slow or fast signals.
Usually about 5 to 10 characters are required for speed synchronization of Morse Code.
Adjust the input signal so that the peak value changes from level 6 to level 7.
Make fine adjustments to each parameter according to the reception status.

[Control parameters]
1.Language select English and Japanese(KANA)
2.Audio Input Level
4.BPF of Center Frequency
5.BPF of Band Width
6.BPF of Shape
7.CW Speed Control ON/OFF
8.CW Speed Control Low, Mid1, Mid2 or High
9.Delete All Decoded Text

Since the signal after BPF is output to the audio output, it can also be used as an AF-CW filter.
