I gather that you didn't have this problem when you did your 1-minute test.tamzy wrote:After I record, I listen to the recording and do my editing. Then I export it to an mp3 file. So far every single time I export it to an mp3 file, the first 30 seconds or so is cut off of my recording. I can't figure this out. I didn't even edit that part and when I listened to it, it was fine. Its not until after I export to mp3 that it gets cut off. I thought maybe it was the mp3, but when I go back to Audacity its cut there too... just gone! Does anyone know why this is happening?
The only thing that I could find to repeat what you describe was to take a piece of recorded material, select a portion of it, and then export it using Export Selected Audio instead of Export Audio.
I doubt this would be your problem, especially since you had the problem several times. But is it at all possible that the portion that you edited was highlighted and that you exported selected audio instead of just Export Audio? Then if you loaded the mp3 back into Audacity, the first part would be cut off just as in the mp3.
That's the only way I could come up with that problem. Otherwise, it's a complete mystery to me. I wish you luck in figuring it out!
