Yes, WaveEmph runs under Windows 10 in compatibility mode (Windows 95).
If you get an error message saying Msvbvm50.DLL is missing, just download and install VB:
Several wave editors have an EQ preset for 50/15 µs de-emphasis, (e.g. Waves Q10 plugin)
This issue also applies to DATs with pre-emphasis and Sony PCM-601.
