Hi all
I'm looking to build a simple device that I can put between my headset and my PC's built-in soundcard that will inject the mic signal into the headphones. The headset is closed-back, and I find myself yelling unnecessarily when things get loud. This can be enabled in Windows via software, but the latency is problematic. I know there are plenty of interfaces out there that incorporate this feature (some are dirt cheap), but it would be fun to build it myself.
The mic capsule is an electret. As for power, 5V is easily available via USB, and this can be increased with a small boost converter if necessary.
I'm envisioning a simple single-ended mic preamp for the capsule and then a mixer to add it to the existing amplified headphone signal. Does this sound about right?
