So far, the standard workflow for the extraction of samples from an imd-file is:
1) imdu.com file.imd file.bin /B
2) cmios9 -r -q1 file.bin
-> use "vc2wav *" to convert all VC files into WAV
In my opinion, it might be useful to write open source multiplatform tools “imd2bin” and “bin2imd” which could replace the old DOS programs. (Perhaps, somebody already wrote such tools, I have not searched for them yet.)
