How did cubase set the sub-track file with a sampling rate of 48,000 to 44 100?

1.? What if all your track-splitting documents are? 48000? , the sampling rate of new multi-channel audio projects will also be uniformly set to? 48000? In this way, the imported file will not be generated? "Variable speed/modulation"? problem Shift (in English input method)? +? s? After that, as shown:

2.? Of course, there will always be cases where files with different sampling rates need to be imported. So, as mentioned above? " 1."? After unified setting, import files with different sampling rates are processed. "Resampling" (making it consistent with the sampling rate set by the project). For example, what is the sampling rate of multi-track engineering? 48000? , and the sampling rate of the import file itself is? 44 100? Import first, double-click to open? [sample? Edit]? Dialog box, Ctrl+? Answer? Select all the audio and see the sidebar steps below:

Resampling dialog box:

After this process, the sampling rate is unified.
