Skype has a new function: it is now possible to record video calls.
This makes it possible to record a video call including the audio track. You can reach this function in desktop app as well as in the mobile version under + > Recording. The recordings are then saved in the cloud and can be downloaded later. A recording of only the audio track is not possible, the video image is always saved.
Legally you have to be very careful with the function. Although the other party will be informed that a recording has been started and is taking place now, you must have obtained permission to record it beforehand. You should also be aware that the recordings will end up on some server.
If you need to record conversations such as interviews for professional reasons, the Call Recorder Software from ecamm may be an alternative .
