I own a Lenovo Thinkpad Edge 14, included on it in the accessories section was a program called "Sound Recorder" I used it to record lectures. I would like to go in and get out some of the more important/ favorite segments and edit out the rest. However when saved Sound Recorder files go into the documents section, and when I try and put them into Windows Movie Maker it will not recognize the Sound Recorder files. Does anyone have any suggestions or any programs I could download that would allow me to edit these files?
