Morse_decoding with a Goertzel filter for android.
Orginal code from
CW Decoder made by Hjalmar Skovholm Hansen OZ1JHM http://skovholm.com/cwdecoder
His code is for an atmel 328 - Arduino
This is a test if the same aproach can be used for an Android device.
See all the comments from Hjalmar on his code how this decoding is done.
The Arduino C code is converted into B4A code. For Android the Nano timer is used and it seems to work.
