Is the AudioBuffer occupies too huge bytes?

Development environment:

• Windows 11

• Node.js v18.12.0

• web-audio-api package version 0.2.2

Sample code

import waa from "web-audio-api"
import axios from "axios"

const url = "https://music.163.com/song/media/outer/url?id=1991012773.mp3" // audio url
const context = new waa.AudioContext()
axios.get(url, {
    responseType: "arraybuffer"
})
    .then((res) => res.data)
    .then((buffer) => {
        context.decodeAudioData(buffer,
            (audioBuffer) => {
                // do something ... 
            },
            (err) => {
                // do something ...
            },
        )
});

setTimeout(() => {}, 10000)

Then in the TaskManager, this Node.js process will occupy over 250 MB of memory.

I guess that there is a problem with the decodeAudioData function in the lib/utils.js, or is there any problem with my sample code?

By the package heapdump, I found that the AudioBuffer generated by the AudioContext.decodeAudioData function usually occupies over 50 MB of memory when the source audio file is less than 10 MB. Is that normal?
