# Touchdesigner + audio multichannel output

##### For performance and stability reasons, it is not advisable to use multiple audio device output operators in 1 patch. That is why you mix your files before they are sent to the audio device output. Below are several examples.

### Example 1

There are 6 audio channels (speakers) in this audio out CHOP. With the merge you combine the sources. In this example I have 2 stereo files and 2 mono audio tones. 6 channels in total. You can also change the order in the merge if you want.

when you want to direct 4 audio files to 4 seperate outputs you should work with mono files.

### Example 2

In this example 1 stereo file is played across all speakers. However, over speaker 5 and 6 there is a separate tone that can be activated with the keyboard buttons 1 and 2.
