Can I add audio with no transcoding or filtering on export?

[S.Lundin]

I am using music from an a studio and want to be sure it is not being altered in any way. I don't see any option to just copy the video when I export and look in the Audio section of the output.  I can do all the basics like getting the audio into the video and synchronizing it.

Is there a way to have the audio used without any post processing; a plain copy from an mp3?

I use Premiere Pro 23.2.0 bld 69.

Happy Trails

Using a lossy codec (mp3) in any NLE project will lead to a re-encode regardless of whatever output you choose. NLE means you're making changes to existing media and then export it out to a new format.

If you wish to preserve the best quality, it is better to request the source material instead of using an already compressed Mp3 as your source (e.g. a master wav file in 44.1 kHz or 48 kHz). That way, the export of your video will contain an audio track that it is encoded from the original file quality, instead of being re-encoded with additional quality loss, however imperceptible to the ear of the beholder.

Hope this helps.

thank you, and a good suggestion.
