How Do I Sync (Audio) Waveforms

[jw17307866]

Hi Guys, sorry to bother you again.

Very quickly, I need help syncing two audio clips from within my timeline.

As you can see (from the photo below) I have two of the exact same audios, one a shortened version (ended the recording early) and a long version (continue to record the audio, but waited for the song to finish), how do I sync these two audio's so they match perfectly in time?

Ps: Problem is, I've used the second half of the song/clip for the first part of my video, and I want to continue the song from the same point later on in my/the timeline.

How is this possible?

To be perfectly honest, depending how exact you want this to be, you're best off doing this in Audition. The reason being is because you are limited to the nearest video frame based on whatever your sequence is set to (probably 24, 30, or 60 fps if you are in the US). Unless the record start time was synchronized, you can't get the waveforms to match exactly. I assume that you recorded the audio on two separate devices with different start/stop times. In Audition you can line up your audio clips much closer because by nature of Audition your session (or "timeline" in Premiere terminology) allows you to get in closer than whole video frames. I would import your video and audio that is already in sync into Audition. And then add the audio file that you want to sync with the rest. Then you can import that newly synchronized file into Premiere.

Hi Brandon, great help. Any chance you could help me get this sorted?

(Never used audition before / First time on Premiere)

It would be hugely appreciated.

You CAN move audio inside premiere in sub-frame increments.

Click on the 3-bar options button next to your sequence name on the timeline panel > choose Show Audio Time units. You can now move audio at the sample level.

I agree with mikedzk. I just tried what he suggested, and that is much easier. I actually wasn't aware of the Show Audio Time Units option in Premiere and learned something new today. Thanks for pointing that out, mikedzk! That will save me a lot of work in the future, too.

It doesn't appear anyone gave the following solution to the original question. So I might as well:

You can sync audio tracks by selecting both of them and right clicking, then selecting "SYNCHRONIZE"

A pop-up window will launch, in that window go down and select the option "AUDIO" if it's not already selected by default (it should be).

From the Track Channel drop down, select "Mix Down", click OK.

This SHOULD sync your audio tracks based off of the waveform information.
