How to generate a QR code for the recording, and you can listen to it by scanning it with WeChat? Let me share a small program, which can be generated directly on the mobile phone without downloading the app, and the operation is very simple. Recorded voice audio, nice music mp3 can generate QR code.
Step 1: Pull down the WeChat chat interface and search for the applet "Audio QR Code Generator" . Don't make a mistake, because there are many counterfeit ones. The name of the applet is "Audio QR Code Generator", click to enter after finding it.
Step 2. After entering, you can see that the interface is very refreshing without any advertisements. Just click to start making.
Then there are two options, one is to record the voice in real time, that is, to record the speech on the spot. Of course, you can turn on the background music softly when recording. The other is to upload ready-made audio, as long as there is audio in the chat history, for example, a friend has sent you an audio, or you have sent an audio to a friend, you can choose this.
After this step is completed, click "Next step to generate a QR code", and then wait for the automatic review to complete. In about ten or twenty seconds, the QR code can be generated.
Save the QR code, then scan it with WeChat, or recognize it to see the audio. It's that simple, and there are no advertisements in the whole process. Note that instead of long-pressing and identifying in the mini program, it is to use WeChat QQ to identify or scan.
In addition, the applet also provides many advanced functions. For example, a password can be set, and it cannot be opened without a password, which can effectively protect privacy. This is really suitable for me, after all, the current network security situation is worrying.
Then you can also choose to scan the code template, there are 2 different styles to choose from. I feel that the designs are all good, they are all in a simple style, and they won't look gimmicky.
The technical principle of recording voice audio to QR code
The so-called audio generation QR code, in fact, is to create a web page containing audio content. After the URL of the web page is converted into a QR code, you can scan the code to access the web page to hear the audio. The general structure is as shown in the figure below.
