.. / Hz.Builtins / Hz.StreamIn

Overview

Have you dreamed of streaming live internet audio directly into your soundscapes? This is Hz.StreamIn reason for being.

There are a few types of internet radio streams:

1. a url suffices to connect to html5 stream (.mp3, .aac)
2. a url may be redirected and utilize context to validate/track the stream.
3. a uri which produces a playlist.

Hz currently supports #1, mp3 and AAC public audio streams that can be connected to via single public URL.

Usage

let ascene = await Ascene.BeginFiber(this);
console.log("Audio scene is ready to go.");
let dac = ascene.GetDAC();
let anode = ascene.NewAnode("Hz.StreamIn"); // magically receives audio packets.
ascene.Chain(anode, dac);
await ascene.Sync();

let [host, stream] = ["https://live.radioradicale.it", "/live.mp3"];
let ret = await StreamMgr.AudioStreamOpen(host, stream, anode.GetId())
console.log(`open returned ${JSON.stringify(ret)}`);
if(ret.tid != null)
{
    // Listen for 20 seconds. Streaming may take a while to
    // get going.
    setTimeout(async () =>
    {
        console.log(`closing ${ret.tid}`);
        StreamMgr.AudioStreamClose(ret.tid);        
        await Aengine.Close();
    }, 20000);
}
