AudioClip (ogg/mp3) loaded from byte array

Questions & Answers
1

For various reasons, I need to be able create an audio clip from a byte containing ogg/vorbis (desktop) or mp3 (mobile) data.

Currently the only viable options I can see are using external decoders (such as NVorbis)… Which seems insane to me.

I don’t need to stream the data, it’s a load it all scenario. Encoded playback would be preferred, but i don’t mind if i have to decode to PCM (which is what i’ll have to deal with with NVorbis).

Any easier way to do this?

Way with handmade web server.

using UnityEngine;
using System.Collections;
using System.Net;
using System;
using System.IO;

public class Main : MonoBehaviour 
{
HttpListener _listener;
string url = "http://127.0.0.1:8080/";

IEnumerator Start()
{
	_listener = new HttpListener();
	_listener.Prefixes.Add( url );
	_listener.Start();
	_listener.BeginGetContext(new AsyncCallback(ListenerCallback),_listener);

	WWW www = new WWW( url );
	yield return www;
	AudioSource AS = GetComponent<AudioSource>();
	AS.clip = www.GetAudioClip( true, true, AudioType.MPEG ); 
	AS.Play();
}

private void ListenerCallback(IAsyncResult result)
{
	HttpListener listener = (HttpListener) result.AsyncState;
	HttpListenerContext context = listener.EndGetContext(result);
	HttpListenerRequest request = context.Request;
	HttpListenerResponse response = context.Response;
	
	byte[] buffer = File.ReadAllBytes( "1.mp3" );
	
	response.ContentLength64 = buffer.Length;
	System.IO.Stream output = response.OutputStream;
	output.Write( buffer, 0, buffer.Length );
	output.Close();
		
	//_listener.BeginGetContext(new AsyncCallback(ListenerCallback),_listener);
	_listener.Close();
}

}

If you dont mind caching to disk, this should work for mp3s (I don’t know about oggs)

        byte[] rawData = byte[];
        string tempFile = Application.persistentDataPath + "/bytes.mp3";
		System.IO.File.WriteAllBytes(tempFile, rawData);
		
		WWW loader = new WWW("file://" + tempFile);
		yield return loader;
		if(!System.String.IsNullOrEmpty(loader.error))
			Debug.LogError(loader.error);
		
		AudioClip s1 = loader.GetAudioClip(false, false, AudioType.MPEG);
                    //or
		AudioClip s2 = loader.audioClip;
