[unity] 音频的二进制流转化为audioclip的两种方式

1、将返回的byte[]数组，转换成float[]数组，然后将通过
audioSource.clip.SetData()方法，将音频数据赋给audiosource，实现语音播放；但这种只有wav很有可以直接用mp3需要第三方库，我没有试过

 int SampleRate = 24000;
 AudioClip _audioClip = AudioClip.Create("audioClip", SampleRate * 600, 1, SampleRate, false); 
  byte[] originalData = response;
 float[] _clipData = new float[originalData.Length / 2];
 for (int i = 0; i < originalData.Length; i += 2)
 {
    
    
 _clipData[i / 2] = (short)((originalData[i + 1] << 8) | originalData[i]) / 32768.0f;
 }
              
_audioClip.SetData(_clipData, 0);

mp3的请参考：https://blog.csdn.net/L877790502/article/details/119042479

2、将返回的btye[]数组，使用filestream，先保存为mp3文件，然后，再用www类，读取本地文件，获取www,audioclip，在赋给audiosource，进行音频播放。

private void ConvertSound(byte[] respone)
{
    
    
	File.WriteAllBytes(Application.streamingAssetsPath+"/temp.mp3",originalData);
 	StartCoroutine(Application.streamingAssetsPath+"/temp.mp3");
}

IEnumerator GetAudioClip(string fullPath)
{
    
    
  fullPath = "file://" + fullPath;
    using (var uwr = UnityWebRequestMultimedia.GetAudioClip(fullPath, AudioType.MPEG))
    {
    
    
        ((DownloadHandlerAudioClip)uwr.downloadHandler).streamAudio = true;

        yield return uwr.SendWebRequest();

        if (uwr.isNetworkError || uwr.isHttpError)
        {
    
    
            debugSongPath2.text = uwr.error;
            yield break;
        }

        DownloadHandlerAudioClip dlHandler = (DownloadHandlerAudioClip)uwr.downloadHandler;

        if (dlHandler.isDone)
        {
    
    
            audio.clip = dlHandler.audioClip;

            if (audio.clip != null)
            {
    
    
                audio.clip = DownloadHandlerAudioClip.GetContent(uwr);

                Debug.Log("Playing song using Audio Source!");
            }
            else
            {
    
    
                Debug.Log("Couldn't find a valid AudioClip.");
            }
        }
        else
        {
    
    
            Debug.Log("The download process is not completely finished.");
        }
    }
}
