I want to slow down the audio so it is as slow as the video, maybe there is a velocity type envelope dor the audio like there is for the video. I am using vegas 4.0
Don't think you can use an envelope but you can ctl-drag ends. You then nned to decide if you want to hold pitch and whivh method to use. I think more than 10% and it gets dicey. Right click event and under properties select pitch shift method.
