melodea Posted January 12, 2021 Share Posted January 12, 2021 I'm trying changing the sample rate from an existing session from 44.1 to 48 kHz. I tried both ways: A) first change the sample rate from the session and then copy/convert the session audio files from 44.1. to 48 and B) copy/convert the audio files and THEN change the sample rate of the session. I haven't found the bomb proof procedure yet. Both ways make some files run out of sync in the session after changing the sampling rate.

melodea Posted January 12, 2021 Author Share Posted January 12, 2021 I have sessions with guitar tracks recorded in 44.1. I want to record new tracks with axe FX II which is running only in 48 k. I have connected the axefx with spdif so I have to change the SR of LPX. Quote Link to comment Share on other sites More sharing options...
Solution David Nahmani Posted January 12, 2021 Solution Share Posted January 12, 2021 What happens if you: 1. Change the project sample rate to 48k. 2. Control-click the audio regions and choose Convert to New Audio Files and set the sample rate to 48k? Make sure you have a full backup on a remote storage device or cloud first!

melodea Posted January 12, 2021 Author Share Posted January 12, 2021 That's it! I will not change the SR of the regions anymore in the file window. Quote Link to comment Share on other sites More sharing options...

MikeRobinson Posted January 12, 2021 Share Posted January 12, 2021 Here's a question for David ... I know that in digital-image and video work a rule of thumb is: "always sample down." So, would it make an audible difference if the new material were sampled down to 44.1K, completing the project consistently at 44.1K, instead of sampling the old material up to 48K?

The audible difference would be rather subtle but in any case this user's issue is that the device they're using works only at 48k so upsampling the project to 48k does make sense in this case.
