Does NI or iZotope have a product that syncs audio files?

Looking to sync a number of audio files. Easy to do with video editing programs when there is video associated with the audio track, more steps if only audio in those systems. I'm looking for SW that is designed just for audio.

Thanks!

    What are you trying to do exactly, and what's the content and context?

    Are these files separate tracks from a multitrack (music) recording?

    Are they dialogue? Are they unrelated?

    Are you trying to mix stereo tracks together like a DJ? Are you creating a mashup?

    Hi PK,

    Thanks for the response. In this case, I am looking for SW that will sync multiple channels of audio, recorded with different recorders. They could be different lavs during an interview or different recorders during a concert. Could be two or more tracks, could be a mix of mono and stereo tracks. I can do this in Davinci Resolve, but looking to see if there is an audio only SW. I currently use RX11 for my regular restoration work, but I don't see a component for syncing audio (not really its purpose…). Any thoughts?

    Thanks!

    OK so they're just different recordings of the same event - in which case they shouldn't need syncing. It would be more accurate to say they need aligning. They shouldn't drift once the start points are the same.

    Really any audio editing software capable of handling multiple tracks should be suitable.

    For free, maybe Audacity. Personally I'd probably use Adobe Audition.

    Thanks PK. Not in the Adobe world. Was hoping there was something in iZotope or NI.

    Would Waves Sync VX help at all? They advertise it as "The New Standard in Vocal Alignment" - https://www.waves.com/introducing-sync-vx

    Thanks Mykejb. Quick check and I don't think I have the right system for it.

    I just saw Sound Radix's Auto-Align Post 2, Anybody have any experience with it?

    Note: I tried to include the link but got a message that I need to be around longer…

    Source : What is phase in audio? 5 ways to address phase issues

    Azimuth module in RX 11
    the Azimuth module in RX 11 provides an easy and accurate way to align stereo pairs of mics. If your overheads—or other stereo pair—are already a stereo file, you’re ready to get started.

    Neutron 5 Phase
    You can also do this in Neutron 5’s Phase Module within your DAW of choice. This is especially helpful for two mono overhead tracks that make up a stereo pair: simply route the sidechain of one overhead track into the other, hit the Learn button, and Neutron will adjust the phase rotation and time-alignment of the signal to match the sidechain input

    Thanks PoorFellow. Cool, I haven't used the Azimuth module yet. I haven't see stereo tracks out of alignment, though I could imagine distance from mics be a problem. I'll have to look into that…

    The problem I would love to be able to fix in an automated way is when I have multiple tracks, typically a mix of stereo and mono, where there seems to be a minor difference in speed between two or more of the tracks. I thought it could be due to batteries dying or even out of cal recorders, regardless, it is a major pain to keep chopping and shifting. I saw this on a multi hour interview. Maybe Auto-Align Post fixes this. Anybody ever use it?

    What are you doing with the tracks after? Are you not using a DAW at all?

    I recommend clapping at the start and end to aid with aligning them.

    Actually, if you're using davinci resolve, I think you should still be able to sync your audio tracks without video

    Thanks RedNick. When I am doing the production side as well as post, I do make a sync noise, but for my restoration projects, I am doing post only. I am currently using Davinci Resolve Studio to align my tracks. It works good enough but not in all situations. I am not using a DAW, though Resolve does have Fairlight built in and I do use that to round trip tracks to RX11 for processing. My challenge is when I am doing strictly audio work and have multiple audio tracks. Sometimes I get an interviewee that starts in one file, cuts out for awhile, and finishes in another file. Sometimes I get a track that slows down over time. I haven't invested in a DAW since mostly I do video work, but for those big audio only projects, it would be nice to have what I described above. Since Auto-Align has some integration with Resolve, I may end up trying that out. Not sure it does everything I want, but I'll let you know what I find out.

    There is also a new plug-in from Waves Audio called Sync Vx.

    Thanks victorp.sg. Mykejb mentioned that above. Not a good fit for my application.

    Thanks for all the comments, I think I'm good for now.

    Try the trial of Auto-Align Post 2 :

    Quote Reddit : auto align post 2 by sound radix, which does dynamic time and phase correlation for different mics. the only issue with auto align post 2 is that it's tremendously expensive (hundreds of dollars; even on sale i think it's like $200). although you may be able to get away with using the trial version for now

    Else , just found this : Shotcut is for video with audio and at a glance it is completely impossible for me to evaluate if it can work on audio only and also how well the audio align works is just as impossible for me to judge. But the great thing is that Shotcut is free . 😀

    Check this out yourself : Shotcut documentation : Timeline > Align To Reference Track .

    Also , this appear as can do align but not auto align so maybe of no use for you but I will place for reference :

    For Audacity :

    Align Tracks

    Aligning Multiple Tracks

    Nyquist Plugin Installer

    Thanks again PoorFellow! I appreciate your responses. I downloaded the Auto-Align Post trial, and will give that a shot when I get a chance.
