===Frequency Divider (AUDF0/1)=== [[Frequency|Frequencies]] are generated by taking 31399 [[Hertz|Hz]] (31113 [[Hertz|Hz]] for [[PAL]]) and dividing by the 5-bit value supplied.<ref name="flop">{{cite web |title=Sound Chips in 8-bit Computers |url=http://flop.atariportal.cz/content/62/en/ZVUKE1P1.html |website=FLOP Atari portal |access-date=14 December 2023}}</ref> The result is a cheap [[frequency divider]] capable of detuned notes and the odd tuned frequency. The TIA is not a musical chip unless the composer works within the frequency limits or modulates between two detuned frequencies to create a [[vibrato]] tuned note. The TIA is tuned to the inverted harmonic series due to each frequency being the base frequency divided by a whole number.
