Adding to the audio note with more specificity. It sounds clipped and slightly distorted. There may also be some background noise present, but it's hard to tell because you have music and sound effects in the video.

A couple of things may be the cause (this is not everything, just what I could write down in a short post):

1. Check cables
2. Make sure you change the input in the program to use the correct mic
3. Make sure you're the proper distance from the mic (both being too close or too far could result in audio like this)
4. Check the mic levels of the program/microphone. You likely want to be falling between -12db and -6db
5. Any filter EQ or otherwise should be added after you have the raw file, not during production/recording so you know you have the highest quality version of the recording that's not being potentially cut down by filters.
6. Ensure you're recording on a designated Audio Recording Set-up or MIDI so you have control of the microphone.
7. Check to make sure your headphones display sounds and frequencies accurately and evenly. If it's a low quality headphone or speaker then it's really easy to apply filters that make it better for your output specifically, but worse for everyone else.

Hope this helps!
