When I am in audio recording mode I keep hearing my input in a slight delay. So it is so freaking annoying how do I turn off the option of hearing myself.
Although you've not specified exactly what hardware you are using to hear yourself, headphones or speakers etc., I think you need to consider eliminating the delay, known as latency, rather than turning off the option of hearing myself.
Latency, caused by unavoidable processing delays in your computer hardware, is a "fact of life" for digital audio.
The solution is to use an ASIO driver for your soundcard, whether built-in or discrete. You've not said which version of MM you have but recent ones have all included an ASIO driver, though some early Magix ones proved more than a little problematic for some users. If you find that using any built-in Magix ASIO driver you have creates more problems than it resolves, do a search online for ASIO4All and install and try using that as your audio driver.
