I’ve recently started digitalising old audio tapes, using a cable from my mic out on my stereo to my audio in on my notebook.
Works fine, but I felt like the audio was just a tiny bit too fast and I compared it with some old recordings of the same tapes I still had on CD and there’s about a difference of 2 seconds on every 6 minutes (which is obvious rom the waveforms). So nothing major but it does feel like I’m not getting the audio that’s on the actual tapes this way?
Mind: these are recordings I did with friends as a kid so ‘just getting the CD’ isn’t an option
Today I also played one of my audacity recordings and the original tape at the same time and noticed even then the audacity one eventually started to get out of sync because it was just the slightest bit faster. I noticed my mic in was set to 48000hz instead of the 44100 the project mentioned but even after changing that there’s still an ever so slight difference and I’m not sure how to fix it? Is it an audacity bug, a soundcard thing, anything else?
Suggestions how to fix already recorded audio without losing much quality would be useful as well, cause I’m not looking forward to recording hours of audio again if it’s not necessary
I’m on Windows 10 and Audacity 2.4.2.
