It's another external program made before Sony build there own. It doesn't prevent converting digital-in recording like Sony, but you still have to transfer USB via SonicStage. But i doubt you can get a bit perfect result using HiMD with digital-in (same record in HiSP converted with SonicStage and HiMDRenderer, and the wavs don't match in EAC. I haven't done the test with PCM yet).
