<p>There’s an incredible amount of radio signals. It’s impossible to know them all, let alone recognize them. So why not get help from <i>SignalID?</i></p><p>At the moment, it recognizes about twenty signals (complete list in the application). With only 5 seconds of recording time, it tries to recognize the signal. To use it:</p><ul><li>Set the frequency and bandwidth properly.</li><li>Selecting the frequency range. (0-30 MHz / Other)</li><li>Place the microphone of the telephone near the loudspeaker. (The quieter the environment is around, the fewer errors will occur)</li><li>Press the big button that dances.</li><li>Wait 5 seconds. (Time required for record)</li></ul><p><b>Tips:</b></p><ul><li>The algorithm is based on frequency, a wrong tuning of your radio/SDR will result in an erroneous detection.</li><li>The recording is limited to 5 seconds, for practical reasons. Recognition of a signal may require several attempts.</li></ul><p><b>Note:</b> author no longer provides APKs, and development sopped in 2020, so there won't be any updates here.</p>
