How do i get my audio to stop overlapping? i.e, out of sync, and audio drift?

So what i’m trying to do is compare mono and stereo mixes by putting them together at the time, but what happens is, when i get the mono recording lined up with the stereo mix, it starts goes in and out of phase, There is this flanging/phasing effect. I’ve tried aligning the tracks together and putting them in time sync, but nothing is working. How do I fix this please?

You may not. Where did the two tracks come from? Your error sounds like two different passes of a phonograph. My Empire turntable weighs more than a Land Rover to get around this speed change thing. If your music came from an electronic turntable then that’s the way it is. Those try to use servo and electronic damping to match speed. The cheaper turntables don’t bother.

Phase matching is stickier than many people think. Any compression or signal management is going to mess up a phase match. MP3 anywhere is a kiss of death.

I don’t use analogue equipment. The tracks came from YouTube Vids of the same song then i converted the videos to MP3 formats. If this is not working, what should i use? FLAC, maybe?

They’re also at the same speed. They’re 2 recordings of the same song, 1 is the mono mix, the other 1 is the stereo mix, and vice versa.

They’re also at the same speed.

I can’t account for the second-by-second wandering.

Wild guess: MP3 and whatever compression YouTube is using aren’t one process. They’re dynamic. They shuffle tone, balance and musical expression around slightly so the filesize is tiny without anybody being able to tell what they did. But they did make changes.

My silly example is a violin performance with two crappy violins and one really good one. After conversion to MP3, the performance more or less sounds the same, but you may not be able to tell which is the good violin any more. That’s the kind of tricks that compression systems use.

A stereo show and a mono mix of the same show are not relatives of each other. They are two completely different compression tasks, and it’s not just MP3. YouTube plays tricks, too. You can try FLAC or WAV, but I’m guessing the damage never goes away.

but I guess you don’t know what equipment the makers of the YouTube videos used, or what processes their videos went through. One thing is certain: they don’t guarantee that the videos are sample accurate.

Thanks. Ill try FLAC,
