The simpler the signal, the better the results. If you have other effects on the track you’re loading Audio Sender into, make sure to put the Audio Sender plug-in first, so the signal is as close to the source audio as possible and unaffected by the other plugins. Another thing that will affect the results is if the signal is distorted or it is clipping. Make sure that the audio is clear and easy to hear but not too loud.
