https://github.com/BH4HPA/taro-app-demo-decode-audio-data.git
小程序基础库: 3.7.2
使用框架: React

复现步骤

1. 点击 「Test API」按钮后看控制台输出
2. 删除 @ts-expect-error 看 TypeScript 编译器报错

期望结果

1. 函数签名应为 微信开发者文档 中规定的

interface WebAudioContext {
    decodeAudioData(
      audioData: ArrayBuffer,
      successCallback: (buffer: AudioBuffer) => void,
      errorCallback: (error: any) => void
    ): AudioBuffer
}

2. 方法应该直接返回 AudioBuffer 而不是一个 Promise 对象

实际结果

1. 实际的函数签名

interface WebAudioContext {
    decodeAudioData(): AudioBuffer
}

2. 实际返回了一个 Promise<AudioBuffer> 对象

测试代码

    const audioCtx = Taro.createWebAudioContext();
    console.log('Start decoding audio data...');
    // @ts-expect-error
    const result = audioCtx.decodeAudioData(new ArrayBuffer(0), (buffer) => {
      console.log('Decoded audio data:', buffer);
    });
    console.log('direct result:', result);
    // @ts-expect-error
    console.log('promise result:', await (result as Promise<AudioBuffer>));

测试结果
