No, it's not a virtual audio interface, it's an app that can record the output of various applications. It can't route audio between different applications like a virtual AI can.
Okay. But then I believe Rogoue Amoeba's "Loopback" would classify as a "virtual audio interface", right?
(I know when you add a "device" to Loopback the is a "Channel Mapping" setting, and if you choose "Manual", I believe you can assign the device to different channels. But that is a future chapter in my learning!!)

If one channel, then should it be on the Left or Right channel?
A human voice is a mono source, it will always be a mono signal, that you can choose where to position it in an overall stereo (two channel) soundfield.

If I can find the time!
desmond wrote:I'd recommend some slight separation in stereo files, ie with each listener panned a little way to each side, to help with separation, but don't go too far, and don't put one voice in the left channel and one voice in the right channel - that's borderline unlistenable in headphones.
Is there a book (or website reference) that could give me a crash course in this?
Sounds like a fascinating, yet complex topic!
desmond wrote:Remember your output file, a stereo file will be bigger than the equivalent mono one, which may have bandwidth implications. You may be fine serving a mono file, in the end, perhaps. Only you know what your requirements are.
In 2018, I don't think that is an issue for most listeners. (In 1995 with 56k dial-up modems, probably yes...)

That's what "mixing" is. You position and balance your various audio sources within your stereo mix as required.
Again, are there any books that could give me a crash course in this? (I am fascinated by all of this, but don't have months or years to learn. So something that helps me learn enough to be dangerous in a weekend would be ideal for now!)
audio_jungle wrote:Does the final mix for my voice on one channel and the guest on another?
No. See above. Have you ever listened to a podcast that does this?
First, technically I have never listened to a podcast. A true podcast requires you "subscribing" and I am not sure how all of that works yet. (Again, 10,000 things to learn and so precious little time to learn them in!!)
When I say "podcast" what I am talking more so is just a "radio show", and I have been listening to those for over a decade.
To your above questions - being a layperson - I guess I have never really noticed where sound comes from?!
Even with music and stereo - being a layperson - I don't think my brain really appreciate what all sound engineers do to add to my experience. That is by definition why I am a layperson!!!
When I think of classic music (e.g. Pink Floyd's "Dark Side of the Moon"), then I guess my brain can better appreciate how stereo and separate tracks can add to the concept of "space and time", but when I listen to NPR-esque shows, I guess I haven't ever really noticed how they separate people talking and other elements.
This is why I want to learn from experts like all of you and start seriously studying all of this.After this weekend, I am hooked on sound engineering!!!
audio_jungle wrote:Does everything get merged together into one channel or two?
Yes, in general, you want to mix your sources (your various audio channels) into a two-channel stereo mix.
audio_jungle wrote:By the way, what is the difference between a "channel" and a "track"?
Imagine you have four mics (four people talking). You have four channels of audio. You could choose to record each channel to it's own audio track. Or your could create a mix of those four and record them in stereo to two tracks. Generally speaking, when referring to "channels", they are mixer channels, and "tracks" are tape/recorder tracks that you are recording to.
So "channels" are really synonymous with "audio input sources", right?
It seems like "tracks" are basically synonymous with "output sources", right?
And to take that farther, you imply that "tracks" really boil down to your ears and either "left", "right" or "both", correct?
Of course, if that is the case, then what about when I hear musicians talk about how they recorded their classic albums using an "8-track recorder" or a "16-track recorder"?
If your final audio producion had 8 or 16 tracks, how would that add value (or take away from value) to the lisetner's experience when they only have two ears??
desmond wrote:A mixer will allow you to route whatever incoming audio channels, to whatever recording tracks as required. Ultimately, you will end up with a stereo mix, with two tracks (left and right) coming up on two mixer/playback channels (left and right).
I am thinking that Loopback will do that, but I have so much to learn, and to be honest, while Rogue Amoeba seems to have awesome software for Macs, their documents and support sucks...

Yes, I am making progress thanks to everyone here at SOS!!
