I may add 8SVX support - possible AIFF too, so people can use Audio Evolution. To be honest, though - it's not a high priority. Back in the days of Amiga 500s, we had to use 8SVX because that's what Paula supported.... but these days practically anyone with an Amiga capable of sampling has an Amiga capable of WAVs.
I might add it later, though - it's not hard....
Why not just use Datatypes then your app can read any audio format the user has a DT installed for?
