废弃注意，该音频剪辑的_3D参数被弃用，使用AudioSource的spatialBlend属性。

Parameters 参数

name	Name of clip. 剪辑的名称。
lengthSamples	Number of sample frames. 采样的帧数。
channels	Number of channels per frame. 每帧的声道数。
frequency	Sample frequency of clip. 剪辑的采样频率。
_3D	Audio clip is played back in 3D. 音频剪辑3D模式播放。
stream	True if clip is streamed, that is if the pcmreadercallback generates data on the fly. 如果为true，剪辑是流媒体。
pcmreadercallback	This callback is invoked to generate a block of sample data. Non-streamed clips call this only once at creation time while streamed clips call this continuously. 这个回调被调用来生成采样数据块。非流剪辑调用调用是一次性创建，而流剪辑调用是连续的。
pcmsetpositioncallback	This callback is invoked whenever the clip loops or changes playback position. 每当剪辑循环或改变播放位置，这个回调被调用。

Returns 返回

AudioClip A reference to the created AudioClip.

返回引用创建的剪辑。

Description 描述

Creates a user AudioClip with a name and with the given length in samples, channels and frequency.

创建一个给定名称、采样长度、声道和频率的用户音频剪辑。

Set your own audio data with SetData. Use the PCMReaderCallback and PCMSetPositionCallback delegates to get a callback whenever the clip reads data and changes the position. If stream is true, Unity will on demand read in small chunks of data. If it's false, all the samples will be read during the creation.

用SetData设置你自己的音频数据，每当剪辑读取数据和改变位置，使用PCMReaderCallback和PCMSetPositionCallback委托来获取一个回调。如果stream为true，Unity将根据需要读取小块数据；如果为false，所有采样将在创建过程中读取。

JavaScript:

#pragma strict
public var position: int = 0;
public var samplerate: int = 44100;
public var frequency: float = 440;
function Start() {
	var myClip: AudioClip = AudioClip.Create("MySinusoid", samplerate * 2, 1, samplerate, true, OnAudioRead, OnAudioSetPosition);
	var aud: AudioSource = GetComponent.<AudioSource>();
	aud.clip = myClip;
	aud.Play();
}
function OnAudioRead(data: float[]) {
	var count: int = 0;
	while ( count < data.Length ) {
		data[count] = Mathf.Sign(Mathf.Sin(2 * Mathf.PI * frequency * position / samplerate));
		position++;
		count++;
	}
}
function OnAudioSetPosition(newPosition: int) {
	position = newPosition;
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public int position = 0;
    public int samplerate = 44100;
    public float frequency = 440;
    void Start() {
        AudioClip myClip = AudioClip.Create("MySinusoid", samplerate * 2, 1, samplerate, true, OnAudioRead, OnAudioSetPosition);
        AudioSource aud = GetComponent<AudioSource>();
        aud.clip = myClip;
        aud.Play();
    }
    void OnAudioRead(float[] data) {
        int count = 0;
        while (count < data.Length) {
            data[count] = Mathf.Sign(Mathf.Sin(2 * Mathf.PI * frequency * position / samplerate));
            position++;
            count++;
        }
    }
    void OnAudioSetPosition(int newPosition) {
        position = newPosition;
    }
}
