Is there a fix I can do using audacity (using newest version 2.3.0) or some other freeware program? I have ffmpeg command prompt, and handbrake, if there's a command that can manually trim the audio or assign the right alignment. But when I puts it out of sync once more, and I'd also rather avoid the loss generated by exporting an aac as an aac. I corrected it manually in audacity with my eyes. When I follow the instructions and export it creates a sync delay by about half a second or so.enough to give a noticable echo when they are played in tandem. mp4 container (is this the highest quality codec I can convert to and fit in a mp4? I want the highest audio quality I can get). I then wanted to export this track to an aac with highest bitrate (320 seems to be highest audacity allows) in order to place it in an. wav s16's and I mixed those down into a single. m4a in ffmpeg using the basic ffmpeg -i input.wav output.m4a, and I used the newest release of ffmpeg for that. ALso the problem occurs when converting the wav to. Edit: it's 0.0330s delay, not half a second sorry.
