The result is a bizarre distortion that can’t be repaired with audio correction tools. It may have a brick-wall limiter programmed in but it’s not working correctly – it interpolates the audio back to the zero crossing point. In tech terms: It incorrectly processes audio that exceeds zero (which shouldn’t be allowed anyhow) as it goes into the AAF wrapper. In simple terms: when Premiere exports an AAF (with embedded media) it messes up some of the audio, making it unusable. This is a known bug that was fixed in Premiere version 12.0.1 (January 2018) however it’s a problem for any sequence that was used in previous versions of Premiere. Issue 1: Distortion/Garbage audio when exporting embedded AAF from Premiere Pro The Pro Tools Import session notes will show “Pro Tools does not support import of AAF/OMF reference to multi-channel audio files” and likely other errors.Clips may be truncated or missing completely from the timeline.Files will be missing in Pro Tools and won’t relink (despite having the files).Issue 4: When an AAF links to source media, Premiere points to multi-channel audio files (not supported by Pro Tools).Issue 3: Premiere cannot export an AAF with transition effects.Issue 2: AAFs are corrupt/missing tracks if the Premiere sequence contains nested clips.Issue 1: Distortion/Garbage audio when exporting embedded AAF from Premiere Pro.I’ll refer to two types of AAFs: “Embedded” and “link to source” (in Pro Tools terms) “Embed Audio” and “Separate Audio” (in Premiere’s terms). There’s bugs, features that aren’t compatible with the AAF/OMF formats, and very little information from Adobe about any of it. Adobe Premiere Pro is known among sound editors and mixers to be problematic when receiving audio by AAF (or OMF).
