Recording 2 Church services one right after the other?

[kozikowski]

Any time you press record, Audacity will try to produce a fresh new recording -- one under the other. From there you can select one of them and File > Export Selected. If you just Export, you will get a mix-down of the two recordings. The solo and mute buttons to the left will turn each track on and off at will.

It's easy to recreate the original performance by selecting the bottom of two tracks and copy/pasting it to the end of the top track.

As a fuzzy rule, saving a project will preserve the show in mid-edit. Multiple tracks, time shifts, cuts, etc. Projects do not save UNDO. You can open the project later and take up where you left off.

You can save a multi-track WAV file, but it takes special effort and not every player can deal with the resulting sound file. WAV format has always been able to handle multiple tracks, but nobody wrote the software to create them.

One other note. WAV files have a size limitation 2GB/4GB and Projects effectively don't, or it's much, much larger.
