Monitoring line-out signal level

[moose57]

Hello everyone,

I'm a hobby programmer, mostly using LCC (a Windows C compiler), but I also have C++Builder 5.

My question:

How can I monitor the actual 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 outgoing signal level.

My project:

I'd like to make a simple gain limiter for use with a TV card (commercials are ridiculously loud). I can adjust the volume, just need a signal reference.

Thanks.

Actually... line-out OR line-in monitoring would work (the TV card plugs into the soundcard externally).

Thanks.
