I am trying to fix an audio drift issue with Final Cut Pro 7 (I know, I know, why am I still editing with 7??). First of all, I'm trying to remove background noise from my video, so I've exported the audio from my timeline as an AIFF, then I brought it into Audacity or Adobe Audition, removed the background noise, and then when I import it back into FCP, the audio drifts by quite a bit by the end of the video.
The sample rate of my timeline is 48 kHz, the audio is exported from FCP at 48 kHz, and exported out of Audacity or Audition at 48 kHz, so I'm perplexed as to why the audio is drifting. I'm not finding much help with this online anywhere. Does anyone know what the issue might be?? Thanks so much in advance for your help!
