Feature Request - Add advanced match options.

[wingedonezero]

So one of my previous tickets i was having issues with a sync and had to use a longer time which cause high ram usage. Would it be possible to have a button which could show all points that matched and how many times that specific match was found along with what that delay was?

For an example of what i mean there was another app i used before https://github.com/JorenSix/SyncSink.wasm . Once you add the audios and it calculates there is a button to download a list of all the match points and there delays to each other as a json. I had other issues with that other app but that specific feature was very helpful to figure out better or closer delays at time. I also think the way yours does it is much more accurate for audios with videos. But there have been a few times where i cant figure why something wont sync exactly correct or if there is another issue that i cant tell just from listening. And that would help in those cases to visualize what is going on. Or if say there is a difference in the audios im not seeing.

In the case above the list shows every point and there calculated delay along with time codes of both files points in each line. And that would be perfectly fine as well. Im assuming you could just add a log to what you already do that just logs all the points it sees that match and there time codes for both files.

So for example like match file A time code - File B Time code Delay. If that makes sense.

Well I am cross correlating two pieces of audio to check how similar they are and how many samples shifted. Depending on the similarity of the audio tracks this can correlate well or not. If you are unsure, it is better to not make the sample longer, but sample at a different points in time, where the audio is maybe more similar or equally recorded/mixed/whatever.

Also just as an information, I cannot fix drift in audio, e.g. due to different timings in recording hardware. Nor adjust the audio track itself like time stretching or something like that. The whole track is simply offset.

If you compare audio tracks that were previously maybe already cut differently, there is also not much I can currently do, since I am not editing the audio itself.
Just as an example, if there is a second missing in the middle of a clip and you set the start time of the check to somewhere in the first half, than second part gets out of sync in the second half and vice versa.

If theoretically there would be a batch function of "compare 20 seconds of audio every minute", that would take quite a bit of time I guess (depending on your computer and the the length of your media) and also you would still have to check what is correct or not afterwards, right?

Currently I do not see this kind of feature in this app. But if I have an idea on how to improve on the current work flow I will try to build it :)

Maybe i worded that weird or have a misunderstanding. I do understand not correcting audio that has a second or two with extra in the middle or something and that isn't what i was referring to.

Maybe i should ask a question is the value shown say i pick 20 seconds. In that 20 seconds it finds the most matched points that are similar and that is the value shown. Thats how i understand how it comes up with the value and the match percentage. If that is the case what i was referring to is to just log those points i know it does a accurate job most the time. But as a advanced usage i wanted to see the other points it matched even if they arent the most common if that makes sense. I dont want it to correct drift or anything. Just log what it already finds. Because the match score i believe goes up depending how similar and how many points within that period of time that match. If that makes sense.
