Morse Decoder decodes Morse code characters through the built-in microphone of your Android device.

Morse Decoder can be used by Ham Radio (Amateur Radio) operators or anyone else interested in decoding Morse code from a Radio or any other device.
Morse Decoder includes a "waterfall" to show a frequency spectrum of about 50Hz to 2300Hz. A narrow band DSP filter can be set for the frequency of the Morse code tones by tapping the waterfall. The DSP filter is followed by an automatic gain control (AGC) to compensate for changing signal strengths.
The detected signal will be shown as a graph and several algorithms will then detect the speed of the Morse code and convert them into readable text. Speeds of less than 4 Wpm (Words per Minute) to more than 50 Wpm can be decoded.

This is the first version of Morse Decoder.
It has been tested on several Android devices and it performed very well or even better than PC based decoding software. However, since we are not able to test the performance on all 150+ Android devices there is the possibility that Morse Decoder will not work on all devices. If Morse Decoder doesn’t work on your device you can uninstall Morse Decoder within 15 Minutes for a full refund (This is the time frame given by Google and I am not able to change it). If the 15 minutes passed and you are not happy with Morse Decoder email me as soon as possible at Please include your name and the model of your phone in the email. I will then refund you the money as fast as possible. It is important that you include the model of your device. I will try to find the cause for the malfunction or include your phone model in a list of “not working” devices.

    This app almost never decodes, so I'm very disappointed.

    The best app on the android market to decode morse code. If you didn't get it working, you should email the maker and get some help. Works fine on all my android devices. The mic doesn't have to be all too close either. Now, it's hard for it to figure out a straight key (or anything that isn't from a keyer) but there's not much for computer programs that can do that either, right?

    Does work but hopping for something better! Waterfall is to small to properly setup frequency. Maybe making it bigger or perhaps be able to change horizontal axis frequency range would be better. Also even all my apps have quite high input Mic gain, this app gain is quite low. Care to debug? 73 de SV1CDN.

    After several tests the results were awful. A refund please.

    It seems to work well but you have to have the volume up really high, so probably your neigbours will think you are a spy. Would be great if it could.allow external audio input. Samsung galaxy i9000.
