Modern DAWs can use real time stretching if they know the tempo of the original file.
If you have the option to embed tempo in your files I believe it’s called acidize in the plug-in, The DAW is in control all files tempo after dragging it in.

This is the preferred way of working with tempos.
After importing your files with embedded tempo you’re free to create your own tempo map and make the performance live or speed up or slow down with the ease of the tempo track in the DAW.
