无法在 'BaseAudioContext' 上执行 'createBuffer'

Question

Failed to execute 'createBuffer' on 'BaseAudioContext': The number of frames provided (0) is less than or equal to the minimum bound (0)."

我的项目尝试为 Float32Array 流块创建音频缓冲区。

音频上下文初始化

  constructor(loading: LoadingService) {
  ... 
    this.audiocontext = new audiocontext()
  ...
  }

创建音频缓冲区

private onmusicdownloaded = (response: streamresponse) => {  
    if(response.totalchunks !== 0 &&
      isnullorundefined(this.buffers)) {
      this.buffers = new Array<AudioBuffer>(response.totalchunks) //lets me make correct playback decisions
    }     
    console.log('stream chunk received')   
    this.currentbufferdownloaded++
    let rawbuffer = new Float32Array(response.chunk)
    let newbuffer = this.audiocontext.createBuffer(1, rawbuffer.length, 44100)

    newbuffer.getChannelData(0)
      .set(rawbuffer)
    this.buffers[this.currentbufferdownloaded] = newbuffer
    this.currentbufferdownloaded++

    if(this.musicisreadytoplay() === false) {
      return
    }
    this.playrandomdeserttrack()
  }

它在定义 newbuffer 变量的源代码行失败。我不明白如何在不先创建缓冲区的情况下 "provide frames"。

@Kaiido 这很尴尬，但这是正确的答案！我需要记住始终检查我的假设。
