TechRec is designed for small radios that have a continous recording in place. In fact, continous recording is a legal requirement in many countries. TechRec let's you use this legal burden for the useful reason of extracting audio easily.
Without techrec, it works this way: you do a radio show, then you have some folder full of audio files sorted by date. They are typically divided by date, like this
recordings/ 2019/ 2019-05/ 2019-05-01/ 2019-05-01-00.ogg 2019-05-01-01.ogg 2019-05-01-02.ogg 2019-05-01-03.ogg 2019-05-01-04.ogg 2019-05-01-05.ogg ...So if you have done your show from 10:30 to 11:30, you must get 2019-05-01-10.ogg and 2019-05-01-11.ogg, merge them and cut them.
With techrec, speakers can just press start/stop when they are live, and the audio will be cut automatically.
This is the first page. Just a big button to start a new recording
If you click on the big button, a recording start. You can give a name to the recording if you want. Note that the top-right button will let you add new recording simultaneously (no screenshot about that, sorry).
Let's call it "interview".
If you press stop, you get a download button
