If you don't start with timecode, or even a 2-pop or clapper, I can't see any other way than lining it up by eye; finding a common beginning… then hoping they stay approximately in sync.
I've never tried this in Audacity, but in any regular DAW or video suite you can just drag one track against the other roughly by eye, then keep increasing zoom & ...

Do expect drift between non-timecode-locked equipment. This is common. One way to get around it is to feed the sound from your recorder back into the camera, monitor via the camera's audio/headphones out, then use the sound from camera in your edit. Lots of cables, but fewer posts on forums later if you don't run across other complications.
Sync drift can ...

Unless the recording devices are locked to each other or a common masterclock like a blackburst generator the devices will drift over time. The best thing to do is probably slice and readjust as needed, whether thats by song or a really tiny adjustment part way through each song. You could try a slight time stretch but that will probably introduce more ...

Depends on the interface. Normally something like this would be handled by a sync cable and a clock generator that establishes a common clock across devices. This is only available on higher end interfaces though. Using an external clock and sync cables is the only way I know of for reliable shared timecode on multiple distinct devices. Your other option ...

I would go with the clapper method, I have been using it for some time and never had an issue with it. As mentioned it will drift over time but this depends on clip length. Movies and the such typically contain short clips so the drift wont be a huge issue. If you are shooting something like an interview that may just be one long running shot you may notice ...

It depends on how the "length" is measured. Exactly where does a song "end" that is faded out at the tail (as most popular music seems to be)? Or classical music where the venue ambience is included at the end? Also it depends on whether they are measuring from the start to the start of the next song (i.e. including the inter-song gap). It doesn't seem ...

Solution: Send a MIDI SysEx "reset all" message.
What worked for me:
Download MIDI-OX for Windows or KMidimon for Linux. I use Windows so these steps will continue with MIDI-OX.
Start MIDI-OX. Go to Options->MIDI Devices. Select your MIDI input ("E-MU Xmidi1X1 Tab" for me). I actually selected Microsoft GS Wavetable Synth for my MIDI output, but I don't ...

I finally found the solution, hope it will help someone if I share it, here is what I have done:
update the 03 firmware driver (Roland.com website)
then some new Input/Output Midi Ports "TB-03" have been created in
Live 9/Options/Preferences/Midi Sync (until now I only had the one
related to my external sound card).
in Output TB-03/Midi Clock Type, choose "...

There are tools to do this kind of syncing in video editors. I am currently learning to use a free editor (not free source code though), Davinci Resolve. If you search for Multicam sync you will find alternative solutions (the tools allows you to select to sync on audio).

The most likely culprit is that you are using a non-integer frame-rate with your camera, but when you are bringing the footage into the computer it is finding it's way into the timeline at a different frame-rate. Check the frame-rate of the camera. Sometimes the frame-rate is not what it seems.

If you decide on the DSP bunny warren, then you'll be looking at autocorrelation and fft.
the problem with trying to an autocorrelation alignment is that any changes to one of the streams will then render any further measurements moot as you will then have to consider the changes made by the autocorrelation routine on top of the codec artifacts you want to ...

The only way to do this is to build a 'tempo track' in your 'DAW' of choice so that bar-lines appear in exactly the correct spot in relation to the audio. Once you have done this (and it takes time) you will then be able to build midi events that work in relation to the tempo track and they will be in sync with the audio track.

Yes. I can tell you exactly what is wrong.
Your synch is off because the frame rate you 'think' you are recording, isn't the frame rate you are editing at. Consequently when you lay in the audio, it loses synch.
Specs of this camera say that it will record at '30fps' but it is highly likely you are actually shooting at a non-integer frame rate of 29.97fps,...

This is more a workaround than an answer as I did not manage to link the libavformat library to Audacity. So here are some clues using FFmpeg version 4.1 with libavformat.58.20.100.dylib on macOS.
There is a potential issue depending on the container used and the FFmpeg version. Some containers (m4a and mp4 for instance) include a metadata describing how ...

Just another hint. It is not necessary to install the USB drivers for the tb-03 but just the "pattern" setting on the (OUT) midi clock is necessary.
I am using just the MIDI cable to sync the TB-03 (USB just for power, not data).
I have a MOTU Midi express and I set the "pattern" MIDI sync mode on the specific OUT port where the 303 is connected.
By the ...

Sometimes labels re-record the same song for licencing purposes... it can mean, for example, they don't have to pay the backing musicians royalties - or they re-do something because it turns out a sample wasn't cleared. The main vocal might be patched back in from the original, or even re-recorded. It can arise when a track was initially released with low ...

Try using a different Audio input, like Audacity. It's a great microphone recorder and when broadcasting, you can ask the viewers how you sound and change the audio levels and such. If you were to do a local recording, you would have to sync the audio up, but it's usually not a big hassle.

Re: @coaxmw 's answer
Both VocAlign & Re-Voice are good tools, but I'd be careful of 'over-aligning' a choir - I once did it [with VocAlign] & ended up with 80 tracks that sounded like 6 people & had to start over to preserve the 'size' of the end result.
A choir really doesn't align that precisely, even when they're 'good'.
Melodyne might be ...

The two devices drift slightly out of sync like the other person said, I frequently record concerts where I have cameras and separate recorders and have up to 8 tracks all out of sync.
If you don't have access to a program like plural eyes which can sync it for you, the best thing to do is line all of them up at one spot where there's an easily identifiable ...

here are a few clues :
as your protools rig and the camera do not share a common clock reference,
their respective speeds will slowly drift and you will notice that on
long takes, even if you sync their starting point, they will end
slightly out of sync on the editing software timeline.
the easiest workflow in your case, because it doesn't require any

I have experienced the same issue, including just yesterday preparing for a live performance, and thought the unit was broken. Apparently based on your post, it is a bug in the 1x1 itself.
To resolve the problem, unplugging the 1x1 and re-inserting it usually rectifies the issue. Very annoying... This effectively resets the unit.

Had the same problem with E-Mu MIDI 1x1, windows 7 64 bit. Disconnectng and reconnecting the MIDI USB solved the mystery delay.
Thanks.

This exact thing is happening to me. I tried updating the drivers, but that didn't help.
The only consistent feature that seems to take the lag away is to unplug the USB device, wait at least 10 seconds, then plug it back in. Once plugged in again, it works like a charm. Having the device plugged in during boot-up slows it down for some reason. I'm ...
