Why can I hear myself with the mic off

[Deuke Steveo]

The audio track is off/muted and I can still hear myself, when I turn the audio track on now I hear myself twice and it’s annoying because the audio track I’m turning on is auto tune so I’m hearing 2 different voices at the same time while recording.

Your Input Echo is on. In Sonar Backstage Pass its the little headphone botton. In CbB its the one next to the record button on the right side.

If the audio track is not active, Input Echo is not on, etc. (the post explicitly states that the track "is off/muted") - then the most likely explanation is that the "live" pass-thru audio from your sound input device is also being added to whatever output you are monitoring with. For example - can you hear your mic without any DAW tracking set up - or running at all? If that is the case, you may want to find information on the method(s) available to you in changing the sound interface pass-thru monitoring options. It can be especially important with the way that effects will mix in your monitoring. The extra delay from latency alone will likely mess up your autotune performance until you find the right mix setup.

Probably a USB mike.

If you are using your stock sound card, check its settings for 'What You Hear' or 'Stereo Mix'. Turn that off.
