MorseDecoder for Android

11 things about MorseDecoder

1. Manually adjustable parameters include the frequency of the audio filter, the WPM dot/dash speed used for detecting characters, the threshold level of background noise, and whether Farnsworth timing is to be used for detecting spaces between individual characters.

2. The Morse Code Decoder includes both an automatic decoding mode, plus manual controls to allow the decoding of weaker signals in noise and QRM.

3. The Morse Code Decoder includes a built-in spectrogram to help determine the audio frequency of the Morse Code tones.

4. Decoding will not work if the audio filter or WPM are set incorrectly, or there is a lot of background noise or room echoes above the threshold setting.

5. Please aim your iPhone microphone at the Morse Code sound source so that the iPhone's noise cancelling microphone doesn't cancel it out.

6. The Morse code WPM (words per minute) detection speed is automatically adaptive from about 8 to 40 WPM, and can be locked to the current estimated WPM dot speed.

7. The HotPaw Morse Code Decoder translates Morse Code sound into text.

8. Use the optional narrow-band DSP audio filter to help filter out background noise.

9. You can also manually set the WPM code speed if the automatic speed detection guesses incorrectly.

10. Just use the microphone or headset input on your iPhone or iPad for the audio signal input, and watch decoded text appear.

11. A QRQ High Speed WPM mode setting allows decoding much higher WPM speeds in the range of 30 to 80 WPM.
