< H2 > 1. How JavaScript saves data and converts it to the corresponding format < / H2 >

currently working on an iFLYTEK voice (text-to-voice demo)
when I get the data from iFLYTEK
the data are as follows:

Pythondemo

A writeFile completes the writing of the file, even the format of the file (I don"t know Python, and I don"t know whether the writing here is correct).

so what should be used to write in JavaScript

< H2 > 2. Goals and ideas < / H2 >

goal: to convert text to speech

ideas:

1. get the audio data and save it as a wav format file, and then play the file through audio
2. get the audio data and play it directly (how to implement it)

1. adopt blob

Source of ideas ( papersnake )

// 
if (response.headers["content-type"] === "audio/mpeg") {
    const blob = new Blob([response.data], {type: "audio/wav"})
    const blobUrl = URL.createObjectURL(blob)
    const audio = new Audio(blobUrl)
    audio.play()
}

result:
whether to solve: yes
there is a problem: the returned content is base64-encoded content that needs to be converted
