Radio streaming

Questions & Answers
1

Hello to all.

I’m New to unity and I am trying to learn developing applications for mobile devices with 3d graphics. So, in my first application I am creating a driving simulation and I want the player to listen to live radio stations. But, from my research till now, I could not make it happen. Unity’s www library with streaming=true audio clips don’t seem to work. Can anyone help me or give me a tip?

Any help appreciated.

Ps: I prefer not to use plugins since I want to learn do it on my own. Thank you in advance.

I guess this might help

  1. Download bass and bass.net from http://bass.radio42.com

  2. Place the 64-bit bass.dll into your unity root project folder

  3. Place the Bass.Net.dll into the unity plugins directory

  4. Create a c# file

    using UnityEngine;
    using System.Collections;
    using System.Runtime.InteropServices;
    using System;
    using Un4seen.Bass;

    public class AudioStream : MonoBehaviour
    {
    public string url = “http://111.11.11.11:1111/Live”;

    private int stream;

// Use this for initialization
void Start ()
{
    Bass.BASS_SetConfig(BASSConfig.BASS_CONFIG_NET_PLAYLIST, 0);

    Bass.BASS_Init(-1, 44100, BASSInit.BASS_DEVICE_DEFAULT, IntPtr.Zero);

    stream = Bass.BASS_StreamCreateURL(url, 0, BASSFlag.BASS_DEFAULT,  null, IntPtr.Zero);

    PlayStream(url);
}

public void PlayStream(string url)
{
    if(stream != 0)
    {
        Bass.BASS_ChannelPlay(stream, false);
    }
    else
    {
        Debug.Log ("BASS Error Code = " + Bass.BASS_ErrorGetCode());
    }
}

public void StopStream()
{
    Bass.BASS_ChannelStop(stream);
}

// Get the Channel Information
public string  GetChannelInfo()
{
    BASS_CHANNELINFO info = new BASS_CHANNELINFO();
    Bass.BASS_ChannelGetInfo(stream, info);
    return info.ToString ();
}

public void SetVolume(float value)
{
    Bass.BASS_SetVolume(value);
}

void OnApplicationQuit()
{
        // free the stream
        Bass.BASS_StreamFree(stream);
        // free BASS
        Bass.BASS_Free();
}

    }

  5. Registering BassdotNet

.

 void Awake()
 {
 BassNet.Registration("sample@gmail.com", "XXXXXXXXXXX");
 }

Hope this might help you achieve what you are trying to do.

@PaulKevin Thank you for your answer Paul. I am really looking for a no-plugin way so I can code it on my own and learn unity this way. Thank you anyways again for your answer.

Ok. So I managed to make a url stream BUT there are glitches of ~0.5 seconds between clip plays and ofcour the result is not acceptable. Can anyone help me?

The interval is 3 and I call this method on update if play boolean is true. Any ideas?

    IEnumerator streeeam()
        {
            Debug.Log(timer + " INT : " + interval);
    
            timer = timer + 100 * Time.deltaTime; 
    
            if (timer >= interval)
            {             //if(timer%interval == 0){
                if (www != null)
                {
                    www.Dispose();
                    www = null;
                    played = false;
                    timer = 0;
                }
            }
    
            if (www == null)
            {
                PLOG("www is empty. Going to initialize www.");
                //www = new WWW(url);
                www = new WWW("http://dromos898.live24.gr/dromos898");
                PLOG("Downloading...");
                //wait for the download to build up a buffer
                while (www.progress < 0.001f)
                    yield return null;
                PLOG("We got www. Lets proceed.");
            }
            clip = www.GetAudioClip(false, true, AudioType.MPEG);
            yield return clip;
    
            if (clip != null)
            {
                PLOG("Clip is not null. Trying to play clip");
                if (clip.loadState == AudioDataLoadState.Loaded && !played)
                {
                    PLOG("Clip loaded. Going to play?");
                    if (!audioSource.isPlaying)
                    {
                        PLOG("We are not playing. So lets move on...");
                        audioSource.clip = clip;
                        audioSource.Play();
                        played = true;
                        clip = new AudioClip();
                        
                    }
                }
                play = true;
            }
        }

@Ginxx009 That helped me, thank you.

Any way I can use this in conjunction with Audio Source, for spatial sound?
