How can i choose what channel to play my audio by myself?

I have some audio sources in my game, and I set them as 3D Sounds.
Then I set my AudioSpeakerMode to Quad.
Can I choose which channel to play my audio sources by myself?
For example, if i want to play my audio in my front left channel only, how can i do that?
Can someone give me a hand, please?

Since it is a 3D sound, a channel will depend on a location of your AudioSource and your AudioListener in the 3D space. The AudioListener is by default attached to your Camera object. So if you want to play a sound only in your front left channel you have to move your AudioSource to be on the left side in front of your camera. Or just make another gameobject with the AudioListener component attached (there can be only one in a scene).
