Recording - Kazam, can record region of the desktop, among other things
Editing - KDEnlive, shows the sound graph very well and makes it easy to punch in markers with just typing "*", and to then remove pauses and extraneous and erroneous words. You make cuts by typing "x" and then cut in a good place. Cut once more, then type "s" to get the selection tool, select the cut part, delete it. Finally right click in the empty space and choose "Remove empty" space from the context menu. That will move all clips in that channel to the right of the cut left in order to close the space.

Sound: Mono, mp3, bitrate: 96
Video: Bitrate 150kb/s. Encoder: H264. Tune: still image. Variable frame rate, 2-pass encoding.
