Transferring WAV file

I’m new and this is 1st post. How do I move wav file from computer to my digital 8 track recorder?
The wav is 16bit and I believe the recorder wants it to be 16 bit. Do I need an interface? Thanks.

Does it not tell you in the digital 8 track recorder manual?
If you’ve not got the manual they are often available on-line from the manufacturers web site.
