Whenever I try to record with sound it records everything OUTSIDE my computer (ex. keyboard, mouse, background noise, ect..) If I enable stereo mix then I'm able to record sound just fine, but everyone says my mic echoes alot. If I DISABLE stereo mix, my mic is fine but it wont record sound. I just want a way to record sound but not capture my mic while my mic being fine at the same time.

When you turn on your speakers, the speaker sound will be entered in your microphone.
=> You can record echoes, noise, and so no.

To avoid this problem, you should use "Headset"

I can't find it anywheres. I've searched through bandicam and my audio settings.

Ehm... this is an headset:

Headphones with mic.

I use headphones and a single mic plugged into the back of the computer.

Hello,

I think you are using 2 microphones at the same time.
I have 2 solutions for you.

* Solution 1
1) Bandicam setting: Disable the "Secondary Sound Device" of Bandicam



* Solution 2
1) Bandicam setting: Use Primary and Secondary sound device" of Bandicam
2) Windows settings: Go to Volume Control menu of Windows, and click "Options -> Properties -> Playback -> Microphone, and then mute "Microphone" sound

I've tried what you said and bandicam is still recording outside sounds.
I've also tried enabling, disabling, and selected all options of secondary sound device.

Can you choose between Microphone and Stereo Mix etc in Bandicam sound options? Or do you only have one option called something like Realtek HD Input?

If you do have the list of them, I think what you want to do is tell your program that people hear you through to use the mic, and then tell Bandicam to use Stereo Mix + Mic, with Two Sound Mixing checked.

Unfortunately..

The options are the exact same for Secondary device.

Open Realtek audio manager, go to the microphone tab, and enable "Acoustic Echo Cancellation"

This will cancel out all audio that the computer hears as redundant (A.k.A White Noise, or Noise from your game, or other sources that may cause Echo)

Hope that helps
