官网论坛上对于.bt1的说明，提供你参考。
The .bt0 or .bt1 files contain information about the characteristics of the wave file. Band-in-a-Box will make the file automatically the first time it uses the wave file. This saves a bit of time for next time the wave file is used. You don't need to do anything manually to make the file.
(Note: older Band-in-a-Box versions create .bt0 files, newer version create .bt1 files. Both file types serve the same purpose, and Band-in-a-Box 2012 is backwards compatible with the .bt0 filetype) 本帖最后由 jackjack999 于 20-3-16 13:53 编辑
