Morse Decoder for Android Smartphones and Tablets

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

Morse Decoder can be used by Ham 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
