How do I record system audio? I have a Sound Forge Audio Studio 16 and Soundblaster AE-7 installed. I can find no way in the manual to record internal sound.
@Timothy-Clark Internal audio can only be recorded if your soundcard supports some kind of loopback. Check the manual for your soundcard (you can probably download it from the manufacturers website). Usually you can enable loopback inn the driver settings of the soundcard.
If your computer's mainboard has a Realtek Audio chipset you can enable "Stereo Mix" or "What U Hear" in the Windows Sound settings. This might also work with your Soundblaster.

You then need to change the Sound Forge audio settings via the preferences and enable Stereo Mix or What U Hear as an input.
As @SP. stated, some 'PCs allow "recording-what-you-hear" and some do not,. For instance, all my Dell desktop and laptop PCs (going back to Win 95) allowed it. OTOH, I had two Toshiba Satellites that could not...
As I recall, "Record-what-U-hear" was originally a term used on the old Sound Blaster cards. On most RealTek cards, it is refereed to as "Stereo mix" so if that is what you have, select 'Stereo mix" instead of the mic (or whatever) as the default record source in the PC's sound settings... Assuming you have an internal sound card... go to "Options> Preferences> Audio> Record" SF's 'Audio Device type' settings and select Windows Classic Wave driver (or Sound Mapper) and "Stereo mix" in". In either case, the speaker/headphone volume will control the record level.
The other option is installing 'VB-CABLE', which is a virtual audio cable. All audio coming from the 'CABLE' output is throughput to the input. Confirm that "Monitor' is disabled in the SF "View> Record Options" menu, or a runaway feedback loop can occur.
