I'm a hobby programmer, using mostly LCC (a Windows C compiler), and also have C++Builder 5.
How can I monitor the actual line-in or line-out signal level on a PC (SoundBlaster) sound card in Windows 9x?
I don't mean get the volume control settings, but the actual signal level.
I'd like to make a simple gain limiter for use with a TV card (commercials are ridiculously loud). Adjusting volume level is simple enough, I just need a signal reference.
The TV card plugs into the soundcard externally, so either line-in or line-out monitoring would work.
