Among them, the sending end encryption scheme:

Base64 encoding is performed on the encrypted information (UTF-8 string) to obtain a base64 string (0-9, a-z, A-Z, +, -), build a correspondence table between characters and frequencies, obtain the frequency array through mapping, and calculate through the energy formula The sine wave audio signal can be obtained and converted into audio for playback. Among them, the energy formula can be found on the Internet, and the character frequency mapping table needs to be constructed by itself, where the characters need to contain base64 encoded characters, that is: (0-9, a-z, A-Z, +, -), audio needs to be based on your own business It needs to be added, for example: I need to play the sound of birds, etc., which can be dynamically configured and available for users to choose.

Receiver decryption scheme:

The main steps of the decryption scheme are the reverse of the encryption:

1. From the sine wave audio signal to the corresponding frequency array;

2. Anti-map to base64 string according to the frequency array;

3. Through base64 decoding, convert it into string information that we can recognize.

The main and most complicated step is the first step, which will be divided into the following six points for processing:

1. Acquisition of audio signals;

Audio collection, no need to go into details;

2. Start syllable;

We call a single-frequency sine wave carrying a character information a syllable; the beginning syllable is to tell the decoder that after the end of this syllable, the following audio signal is a sound wave carrying effective information;

3. Fast Fourier transform;

It is recommended to use the kiss_fft of the classic library Mark Borgerding.

4. Selection of analysis window size;

In general, the parsing window size is larger than the syllable window;

5. Align syllables;

When the analysis window crosses the target syllable from left to right, the amplitude of the target syllable of the Fast Fourier Transform first increases and then decreases, and the middle position of several positions that keep the maximum amplitude unchanged is the closest to the fully aligned syllable s position.

6. Sequential analysis;

After the aligned syllables are found, they are parsed sequentially.

7. End syllable;

When the sequence is parsed to the set end syllable, it means that this information transmission is over, and the parsing can be ended.
