I rustled up this simple electronic circuit tonight, “of necessity”. It takes audio straight off the Internet, and puts it on a digital recorder. There are various advantages to this, not least that you can pull the audio off any computer without having to have this or that software in place. Note that this is a digital-to-analog-to-digital conversion, so the sound will only be as good as your computer's/recorder's analog circuits. OBSERVATION: After wiring up the circuit, set your digital recorder's sensitivity to Lo or Dictation mode. Turn potentiometers VR1 and VR2 back about three-quarters, to avoid overload of the recorder (you might prefer a dual potentiometer here). Turn your computer volume up to about three-quarters, both to minimise hiss and avoid amplifier distortion. Stereo Jack Plug A goes into your computer's headphone output, and stereo Jack Plug B goes into your digital recorder's microphone input. You will probably require 3 mm jack plugs at both ends. Further adjust VR1/VR2 as required for optimal recording. You may click on the circuit diagram to enlarge. To follow the electronics trail on this blog, click on the "Electronics" category top left.

Hi Thomas,
Can you not do that in software by setting your recording input to the stereo mixer, and then record it in Audacity or the like? Then copy the WAV/ MP3/ ogg to your device of choice, after editing?

Thanks for this. I've tried this, but for some reason have never been able to get it entirely right. I also have the problem that my system is so erratic when it comes to CPU-intensive stuff that high quality music is often ruined. Rather plug into another computer and do a quick transfer as per this circuit. If I had you here to make it all work ...
