Declaration

public static AudioClip Create(string name, int lengthSamples, int channels, int frequency, bool stream);

Declaration

public static AudioClip Create(string name, int lengthSamples, int channels, int frequency, bool stream, AudioClip.PCMReaderCallback pcmreadercallback);

Declaration

public static AudioClip Create(string name, int lengthSamples, int channels, int frequency, bool stream, AudioClip.PCMReaderCallback pcmreadercallback, AudioClip.PCMSetPositionCallback pcmsetpositioncallback);
Obsolete The _3D argument of AudioClip is deprecated. Use the spatialBlend property of AudioSource instead to morph between 2D and 3D playback.

Obsolete The _3D argument of AudioClip is deprecated. Use the spatialBlend property of AudioSource instead to morph between 2D and 3D playback.

Declaration

public static AudioClip Create(string name, int lengthSamples, int channels, int frequency, bool _3D, bool stream, AudioClip.PCMReaderCallback pcmreadercallback, AudioClip.PCMSetPositionCallback pcmsetpositioncallback);

Parameters

name Name of clip.
lengthSamples Number of sample frames.
channels Number of channels per frame.
frequency Sample frequency of clip.
_3D Audio clip is played back in 3D.
stream True if clip is streamed, that is if the pcmreadercallback generates data on the fly.
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.
pcmsetpositioncallback This callback is invoked whenever the clip loops or changes playback position.

Returns

AudioClip A reference to the created AudioClip.

Description

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.Sin(2 * Mathf.PI * frequency * position / samplerate); position++; count++; } }

void OnAudioSetPosition(int newPosition) { position = newPosition; } }
