How many channels?

Postby audio_jungle » Sun Aug 19, 2018 3:18 am

On my Mac, I have the "audio sources" for Loopback set to "Firefox" and "Logitech USB Headset".

If I want to record streaming radio and myself talking, how many channels should I set up?

It seems to me that the streaming broadcast should have a Left and Right channel, since the music is supposed to be in stereo.

And I have read that a human voice is considered mono.

So would putting my USB Headset on a 3rd channel suffice?

Or should I have a 3rd and 4th channel for my USB Headset?

Thanks,

Yes, as you've already figured, you want a stereo (2-channel) feed from Firefox, and a single mono channel from your mic headset.

All your reasoning is entirely correct. :thumbup:

Two: a stereo track for the radio, a mono track for the voice.

Would I gain/lose anything by recording my voice in a 3rd and 4th channel/track?

I was fiddling around and expanded to 4 channels. Why is it when I do that and then listen to my recording, my voice sounds louder?

Are the two tracks amplifying my voice, or is there another reason for this?

You're just wasting disk space.

Mixing audio is essentially adding it together. If you have two "3"s, and you add them together, you get "6". In the same way if you play two identical mono tracks, you just get the same thing a few dBs louder (the same as just turning up the volume on a single channel by the same amount.)

Okay.

Okay.

Before I get too deep into all of that, I suppose I better finish learning about setting up my gear!
