we are trying to add effects through the code:
Dim ssOptions As String () = {"--spatializer-roomsize = 1,100000"}
VlcControl1.VlcMediaplayerOptions = ssOptions
it's not working ... and now you tried to put "--scaletempo_pitch = 4" and it didn't work either.
I wanted to transpose the same tone as VLC does when we go to the option settings and effects, audio effects, advanced, I wanted to change the same tone there
