Sound Source You can either have the decoder listen to the microphone, analyse a file you upload or analyse a pre-saved sample along with some sensible parameters.
#Morse decoder source code how to
Please see the help file on the HotPaw website for hints as to how to solve decoding issues. If you cannot produce your own Morse code sounds then try using my Morse code translator to play or download some. 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. or background noise threshold level properly. Please use the manual settings if automatic decoding does not adjust to the frequency, WPM. You can see if sound is getting to the iPhone by seeing a peak in the spectrum display. Please aim your iPhone microphone at the Morse Code sound source so that the iPhone's noise cancelling microphone doesn't cancel it out. A QRQ High Speed WPM mode setting allows decoding much higher WPM speeds in the range of 30 to 80 WPM. You can also manually set the WPM code speed if the automatic speed detection guesses incorrectly. 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. Please do not try to decode tones outside this range. The audio filter works for tone frequencies from 300 to 2400 Hz. Use the optional narrow-band DSP audio filter to help filter out background noise.

The Morse Code Decoder includes a built-in spectrogram to help determine the audio frequency of the Morse Code tones. What can you do with Morse Code Generator This tool allows loading the English text URL, which loads content and Converts to Morse Code. 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. The Morse Code Decoder includes both an automatic decoding mode, plus manual controls to allow the decoding of weaker signals in noise and QRM. Just use the microphone or headset input on your iPhone or iPad for the audio signal input, and watch decoded text appear. The HotPaw Morse Code Decoder translates Morse Code sound into text.
