Answer of FAQ

How do I record the sound that is being produced by the programs that run?

Recording the sound that is produced by a program is difficult because most sound cards do not support to use their sound output as a sound-input for recording.

However, there is a hardware workaround:

What may work is to connect the "Line-Out"-Jack with the "Line-In"-Jack of your sound card with a 1:1 connected Stereo cable, possibly with a galvanic separation device in between.
Please do not connect "Line-Out" with the "Microphone"-Jack because the microphone outputs a power-supply for the microphone and if you connect that power-supply with the Line-Out, you may damage your sound-card. (The "Mic"-jack uses a Stereo-connector but only supports Mono-microphones. The other channel is used for the power-supply. )

Hope this helps,


P.S.: Future versions of DemoRecorder may also support direct capturing of sound-output at a software level before it reaches the sound card. As of now I do not know whether this is possible but I must admit that I didn't do extensive research into that direction. What I can tell is that there is no obvious solution for software-based capturing of sound output.

A possible alternative solution would be direct interfacing between your application and DemoRecorder. We provide a custom development service, so you can order some customizations of DemoRecorder which are needed for that purpose.
