low latency? #22

Hello, thank you for your fantastic projects, I learned a lot from it! I am a guitar player, and I want to build a wireless effect device. There are a lot of wireless guitar tranceiver products on the market in the low price range, ( less than 50 euro). They use he 2.4 ghz band, that's all I know, and the latency is quite good ( about12msec) with very good sound quality ( frequency S/N ratio and dynamics). What is the trick here ?? I can imagine its something like ESP32 Now under the hoods, , in conjunction with a fast compression codec. So, if you could go this route someday ( its probably the opposite to the other feature request, asking for long range with the CODEC 2), that would be great. Thanks!

I would guess under the hood is something more akin to an nrf24 chip not a wifi chip like the esp32
