I know the square wave programmable timer is clocked by one APU cycle(equals two CPU cycles), the triangle wave programmable timer is clocked by one CPU cycle.
How about the noise wave programmable timer?
Thank you.
Only the triangle wave runs at CPU frequencies. Everything else sound related runs at CPU÷2.

Yeah this wasn't immediately obvious to me either. The div-by-two is hidden in the LUTs for the noise and DPCM length counters.
Thank you. I get it.
Today is Mon Apr 14, 2014. I successfully get the info, via wiki, about the term timer which describes the APU channels' frequency.
