I’m using Audacity on macOS Catalina. But I’ve tested it on Windows 10 as well.
- I’m recording video and sound from one device
- Video is capturing by OBS. And sound by Audacity
- On finish, I’m fitting video and audio in video editing program.
Magic starts here: the longer video is, sound becoming more and more desynchronized. It’s like Audacity added extra seconds to audio? I don’t know how to explain it.
Between clicking to start recording in OBS, and second in Audacity, I have a small delay - about 1-3 seconds. I need to switch between programs and click recording. But it’s not a problem - sometimes it takes me 1 second.
The problem is: when recording is done, OBS shows for ex. 1h:5m:15s of recorded video. But in Audacity…it’s like 1h:15s:25s. But…how. OK, I have always a little delay at start. But how’s it’s possible, that Audacity record more time, that video is.
Even if I manually synchronize sound and video in video editing program - it’s great at the begging. But it’s desynchronized after some time. And on start I’ve had 1 second of delay, but after 1 hour of recording, Audacity record for ex. 10 seconds more time than OBS.
I really can’t explain it properly. It’s like Audacity adds extra seconds on records. I really don’t know how to explain it. If my records take 1h:15 seconds, how Audacity could record 1h:15 seconds for example. It’s like a bending in time
At first I’ve thought that macOS Catalina is the problem, because Audacity have it’s problems on Catalina. But recording on Windows 10…this same strange issue. The longer sounds in capturing, the more seconds it have, more than captured video :-/
