You don't have to string-take, the standard pattern is (git-file-name 
name version), as in (guix)Version Numbers.

Why are tests disabled?  There is a bench-test target, maybe you need 
#:test-target "bench-test"? I hope that means "test bench" and not 
"benchmark" though.

On the license: some parts are GPL3+ (see: 
https://github.com/ZipCPU/dblclockfft/blob/master/sw/legal.h), that 
sounds important to add to the license field to me (license 
(license:lgpl3+ license:gpl3+)).
