To be honest this has happened to me before but I can't remember how i rectified it.
When I click on the convolution tab there is no difference in the playback. I have tried different convolutions.
Also adding a digital crossover convolution from audiolense is giving me a double beat and a distorted playback. Now I am not sure if this is from the correction filter itself but as the above problem exists it made me think that this could be JRiver issue and not Audiolense.
Any ideas?
