Is that still the case these days? I filmed a multi cam performance a few weeks ago with an Android phone, a PC laptop, and an iPad. The software (Premiere and others) was able to automatically sync them up just by analyzing their waveforms and lining them up. (You just drag the clips into a timeline and then right-click to sync them... it takes a few seconds to process but it's all automatic)
It was good enough that the audio lined up perfectly except in cases where a performer was standing next to one microphone and far from the other one, which created a noticeable echo delay in stereo. But I think that's just the speed of sound at work, not the software's fault.
My understanding is that this is a normal feature in video apps these days, to the point that a lot of older standalone time sync apps are no longer for sale because it's all built-in now. I'm not a professional in this space though, just someone recording amateur videos for a music class.
