What is this?
In 2009, Two YouTube Videos and a Motherfucking Crossfader turned any browser into a DJ booth:
two YouTube videos side by side and one crossfader between them. It went viral, and it quietly stopped working
when YouTube's Flash player and Google's old video search were switched off. This is the remake: same idea,
same look, working again, on phones too.
How does it work?
Paste a YouTube link into each deck, press play in both videos and slide the crossfader. Under
sound effects you'll find the airhorn, the siren, lasers and gunshots. Under more knobs: speed,
tap tempo, tempo matching, crossfader curves and themes. Under each deck: more videos from the same channel;
click one and it loads on the other deck. REC records your moves and turns them into a link anyone can play back.
Why no EQ or real beat sync?
A web page can't touch the sound of a YouTube video, only its volume and speed, and speed only moves in 5% steps.
So tempo matching gets you close and you nudge the rest by ear. Very 2009.
