The output audio file encoded as Linear16 (uncompressed. Morse Code Audio To Text API - The necessary steps are written below, basically for Morse Code Audio To Text API you send an authorized POST request in JSON format to the API endpoint and you get as JSON response a a link to the saved audio file if you chose so or decoded text. Encode Normal Text To Morse Text (maximum 700 chars per request) and get also the audio wav file with the format requirements from the first point.Īllthough this Morse Code Audio To Text API is intended for software development and therefore developers, we have also here an online application that may be used to get audio files from the input text either plain text or morse code text with characters here.Decode Morse Text To Normal Text (maximum 700 chars per request) and get also the audio wav file with the format requirements from the first point.one dit is one unit, one dash is three units, space between parts of the same letter is one unit, space between letters is three units, space between words is seven units according to International Morse Code), Linear16 (uncompressed wav file), PCM, 44100 HZ, 32 BitsPerSample, IeeeFloat Encoding, BlockAlign 8, Stereo 2 Channels Decode Morse Audio wav file to text with requirements for the wav file format as follows: clear sound (without noises), 150 miliseconds per each morse unit (i.e.It uses cloud infrastructure and artificial intelligence to solve the requests. If you've read this far, you may be interested in the older version of this tool which does not attempt to adapt to the sound and also includes more diagnostic information.Morse Code Audio To Text API - MorseSonat (or Morse Code Sound To Text API) is a cross browsers REST API supporting now also Text To Morse Audio API (as normal text) or Morse Text To Morse Audio API and it may be used by any device that can connect to Internet and send the POST requests to our API as instructed in this website: smartphones, tablets, laptops, PC Desktops, other smart devices. The volume threshold is the value (0-255) which the measured volume in the analysed frequency must exceed to be counted as a dit or dah. The volume filter (which uses dB) discards very quiet (very negative) or very loud (close to zero) sounds and scales the size of the remaining data. There are three parameters which are not automatic: the minimum and maximum volume filter settings and the volume threshold setting. The frequency can only be certain values and the closest allowed value will be chosen. If you want to fix the frequency or speed then click on the "Manual" checkboxes and type in your chosen values. In fully automatic mode, the decoder selects the loudest frequency and adjusts the Morse code speed to fit the data. From these timings it determines if something is a dit, dah, or a sort of space and then converts it into a letter shown in the message box. If the volume in the chosen frequency is louder than the "Volume threshold" then it is treated as being part of a dit or dah, and otherwise it records a gap (this is shown in the lower graph that looks like a barcode). The spectrogram of the sound is shown in the main graph along with a pink region showing the frequency being analysed. The decoder will analyse sound coming from the microphone or from an audio file.
