Online recording tools
Zencastr: https://zencastr.com/
This online tool allows you to record an audio conference and then provides separate files of you and your guests. It can automatically merge all of those files into a single file (though you may have to pay extra for that feature when using the free license), or you can mix them together manually using Audacity. This also features the audio preset trigger buttons that can be customized with your choice of sounds or music.
Descript: https://www.descript.com/podcasting
Descript saves podcast creators from the technical audio and video editing. The editing timeline is text based, not visual, making editing a podcast very similar to editing a word document. Free version is available.

This app offers a free 30 day trial, and is then $10 per month. It features an online editing tool that looks more like a standard audio editing app.
