2: teacher, track volume is a must start in the production of small volume, or the volume (because I read some Youtube videos after the work is to ensure that they seem to choose to start a small volume?)?
2: Teacher, at the time of production, the track volume is the first volume to be low, or the volume? (Because I watched some Youtube videos, and they seemed to make sure that the work after that would start with a low volume?)
2: Teacher, is the track volume low or high at the beginning of production? (because I watched some YouTube videos, they seemed to make sure that they would choose low volume at the beginning for later work?)<br>
