AudioClip A reference to the created AudioClip.

설명

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

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.

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;
    }
}
