Using Ubuntu 16.04.
Is it possible to record into a single audio file the incoming and outgoing signals (headphone and mic) of a wireless headset? With which program and instructions?
I have found some resources concerning ffmpeg in Windows, using the DirectShow tool, which is not recognized in my ffmpeg version 2.8.17-0ubuntu0.1. So I seem to trip at the first step.
Guidance appreciated.
ffmpeg
can use multiple sources, or you can set up e.g. a Pulseaudio "virtual sink" that either mixes those signals, or provides those on different channels. Outgoing signals are available through the associated.monitor
source.
