Android Web Audio latency is over 200-300ms on many devices and is deliberately introduced to kill WebGL browser games that could otherwise bypass the Play Store and its 30% tax. Google has plenty of engineers smart of enough to fix such a glaring latency issue that so many of us have been complaining about for so long but Play Store game profits are in the billions and Google isn't going to let a frictionless browser game experience kill that.
The Superpowered Latency Database[1] has many measurements showing just how bad Android latency is. (A select few devices do OK.) Note that Apple latency measurements look pretty good, because Apple uses different strategies to kill WebGL browser games: (1) Make WebGL slow and lacking features; (2) Prevent browser apps from going fullscreen; (3) Don't even let browser games ask if they can use gyro/tilt control, just block this outright because "Privacy". After all, if Epic Games could just put Fortnite inside mobile Safari their case against Apple wouldn't be so desperate. There's a demo version of Minecraft for the browser that I've never seen work on mobile browsers[2].
