With [timer] I get 1.45125, which is 64/44100*1000 as expected. With [realtime], I would expect a slightly varying value around 1.45125 approximately, but I get values below 0.1!!!!!!
Whooooooops! :$:$:$:$:$:$ That's not true!!
With realtime I get a lot of small values around 0.1 and then, every once in a while, a huge value around 10, and the avarage seems indeed to be around 1.45 so nothing weird at all.
Sorry m.
