# Live Player

In the Live Player, you can route whatever you want, like an external source (iPod, radio, instrument, another computer) or an internal source (iTunes, Spotify, SoundCloud).

## Internal Source

In order to route audio from other programs running inside your computer, you need an internal router. We use `BlackHole` in OSX and `VB-CABLE` in Windows. Both are free and work really well.

### OSX Internal Routing with BlackHole

First, install BlackHole.

1. [Download BlackHole](https://cdn.trainyourears.com/assets/BlackHole.v0.2.6.pkg) to your computer.
2. Open the `dmg` file.
3. Launch `BlackHole.v0.2.6.pkg` to install it.
4. Agree to the License terms and install it.
5. Restart your computer.

Now, open **TrainYourEars** and route the signal.

1. Choose `BlackHole (16ch)` as input in **TrainYourEars**.

1. Choose `BlackHole (16ch)` as output in your system.
2. Now any signal played in your computer should be routed to **TrainYourEars**.

Once you have finished your training, remember to select your normal output again.

If you hear noises try switching to `ad_portaudio Core Audio` driver instead. In certain computers, it works better than `Core Audio`.

### Windows Internal Routing with VB CABLE

First, install VB-CABLE.

1. [Download VB-Cable](http://www.vb-audio.com/Cable/index.htm) to your computer. Scroll down until you see the orange DOWNLOAD button:
