pretty good
But u need to adjust sound. Even if ur using a cheap mic, u can do this:
Turn up the mic recording volume up high and adjust it so that when u speak at ur loudest, it almost hits the red. Whenever u record and the meter goes into the red, u are losing sound quality, because the recorder is clipping it off at that point.
Now that u have ur sound adjusted, record as close, loud, and as clear into the mic as possible. Then when ur ready to mix it, u can lower the volume and reduce that buzzing, background noise. (look up sound-to-noise ratio)
U should also record some audio with u talking n apply that as a room tone. This will help u have a consistent audio track, without the jarring silence when u cut the sound clip.
I hope this helps n i look forward to seeing ur future work.
