[DMDX] RE : RE: Strange problem with voice recording (DigitalVOX+RecordVocal) I played randomly with the settings of record vocal and digitalvox (see help on these keywords and help on audio input) to get rid of a similar yet different problem (my responses were cut in the middle: DMDX sticked together the beggining and end of the words. "constitution" would sound "condchion") what I use now is: in that order and it works on my desktop... xavier >-----Original Message----- >From: DMDX-owner@psy1.psych.arizona.edu  >[mailto:DMDX-owner@psy1.psych.arizona.edu] On Behalf Of  >Matthew Finkbeiner >Sent: Tuesday, June 08, 2004 3:19 PM >To: DMDX@psy1.psych.arizona.edu >Subject: [DMDX] RE: Strange problem with voice recording  >(DigitalVOX+RecordVocal) > > >Are you using a pre-amp?
