<p>You can do this in Adobe Premiere using the multi camera sync function. It works well. </p>

<p>Final Cut Pro X has a very very easy-to-use feature that syncs up separately recorded audio tracks of the same event that. For those who are confused, recording the same event on two different recorders will yield files that don't sync up perfectly, especially if they are an hour long or more!</p>

<p>You can try Ableton live and its wrapping feature.</p>

<p>To glue them together you can also use a bit of reverb and maybe some little compression.</p>

<p>Let's say I have two recordings (or more) of the same event. Maybe one has been recorded slightly slower or faster (different "pitch") than the other one and has been started several seconds after or before the other one.</p>

<p>Let's also say, for simplicity's sake, that there are no gaps in the recordings.</p>

<p>I can synchronize the recordings manually in a software such as Audacity by importing the different recordings as tracks and shifting/stretching them, but is there any way to do that process automatically?</p>

There's no silver bullet, I think. If you have video, you may set anchor points at sharp movements, and align tracks by those points. However, if the recording suffers *jitter*, and jitter is non-deterministic (random), it makes synchronization more difficult.

By "slightly slower or faster", I was thinking of a situation where two analog tape recorders were used to record the same sound/event from two different places and the tapes were not running exactly at the same speed.

Here are two examples of recordings that I might want to align/synchronize automatically:
- several audience/soundboard recordings of the same concert (goal: make a "matrix recording" of the concert)
- several versions of the same album (let's say one original, one remastered, one remixed, etc.) (goal: put version 1 on left channel and version 2 on right channel to compare the two versions; some remixed versions of old albums have elements that are added/missing from a version to another)

# How to automatically synchronize two recordings of the same event?

(Asked by: username_0 on 2012-08-10)

Let's say I have two recordings (or more) of the same event. Maybe one has been recorded slightly slower or faster (different "pitch") than the other one and has been started several seconds after or before the other one.

Let's also say, for simplicity's sake, that there are no gaps in the recordings.

I can synchronize the recordings manually in a software such as Audacity by importing the different recordings as tracks and shifting/stretching them, but is there any way to do that process automatically?

There is a plugin called vocalign that will do this. It is designed mainly for aligning vocal overdub and replacment dialog but it should work for what you are doing. You can use it as a VST in audacity. It isn't cheap but, if my memory serves me correct, it has a fully functioning demo.

I have a theory it maybe works! It's a cheap solution ...

1st download the virtual DJ, second on the left and right you put those 2 recordings you want to synchronize, and you play it together, so the app can synchronize well these 2 songs for example for relative small differences, and if you use the button record, you can record the new mix of these 2 songs in one.

Another option I am very impressed with is [Plural Eyes](https://www.redgiant.com/products/pluraleyes/)no affiliation. It can sync multiple audio tracks with each other and export the timeline to your video editor.

I have used it for the following:

* Sync DSLR footage with sound from multiple external recorders in an interview setting.
* Sync multi-camera footage with sound from external recorder

I am not sure how it will handle soundtrack of differing pitch.

It's rather [expensive](https://www.redgiant.com/products/pluraleyes/#pricing), but there is a [free trial](https://www.redgiant.com/products/pluraleyes/free-trial-download/) to see if this fits your needs. If it does what you want, and you sync tracks often, this will save you a tremendous amount of time and frustration.
