将 AudioData 对象转换为一个新的 AudioData 对象，具有不同的采样率或格式，或两者兼有。

🌐 Converts an AudioData object to a new AudioData object with a different sample rate or format, or both.

Converting an audio data
import {convertAudioData} from '@remotion/webcodecs';

const audioData = new AudioData({
  data: new Int32Array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]),
  format: 's32',
  numberOfChannels: 1,
  numberOfFrames: 10,
  sampleRate: 44100,
  timestamp: 0,
});

const newAudioData = convertAudioData({audioData, newSampleRate: 22050});

/*
{
  data: [0, 2, 4, 6, 8],
  format: 's32',
  numberOfChannels: 1,
  numberOfFrames: 5,
  sampleRate: 22050,
  timestamp: 0,
}
*/

行为​

🌐 Behavior

  • 可能会进行四舍五入。
  • 新的采样率必须在3000到768000之间。
  • 如果不需要转换（采样率和格式相同），则会克隆原始的 AudioData。
  • 对输入或输出 AudioData 都不会进行任何清理（请自行对它们调用 close()）。

应用编程接口​

🌐 API

接受具有以下属性的对象：

🌐 Takes an object with the following properties:

audioData​

要转换的AudioData对象。

🌐 The AudioData object to convert.

newSampleRate?​

新的采样率。必须在3000到768000之间（实际上只有Chrome会强制执行，但Remotion总是会抛出错误）。

🌐 The new sample rate. Must be between 3000 and 768000 (only Chrome enforces this technically, but Remotion will throw an error always).

newFormat?​

新格式。

🌐 The new format.
