Dear friends, Here is a technical question on a problem that is driving us crazy. We want to play sounds from Matlab through an RME Fireface 400 sound card. The problem is that when we play a "silence" interval (array of zeros) we can hear (and even record) a clear transient at the onset of the _silence_ signal. We would very much like to get rid of that onset transient. Any cues as to how to get rid of it? Thank you so much in advance. - Enrique Enrique A.
