Another viewpoint is 8hz = 32 cents. So say your synth is playing in A440 tuning, detuning each oscillator 32 cents would give you a synthesizer tuned to A432hz.
not true: that number will change for each pair of semitones, as the difference in frequency between each pair of semitones is divided into 100 equal parts (even the concept of 8Hz = 32 cents is not supported at the specific example of A=440Hz: 32 cents above A=440 is 8.3712Hz + 440Hz = 448.3712Hz, 32 cents below A-400 is 440Hz - 7.904Hz = 432.096Hz)
for example
A =440Hz
A#/Bb = 466.16Hz
therefore 100 cents between A and A#/Bb = 26.16Hz, and 1 cent becomes 0.2616Hz
G#/Ab = 415.30Hz
A = 440hz
therefore 100 cents between A and G#/Ab = 24.70Hz, and 1 cent becomes 0.2470Hz
now consider the same note pairs one octave lower
A =220Hz
A#/Bb = 233.08Hz
therefore 100 cents between A and A#/Bb = 13.08Hz, and 1 cent becomes 0.1308Hz
G#/Ab = 207.65Hz
A = 220hz
therefore 100 cents between A and G#/Ab = 12.35Hz, and 1 cent becomes 0.1235Hz
now consider the same note pairs one octave higher
A =880Hz
A#/Bb = 932.33Hz
therefore 100 cents between A and A#/Bb = 52.33Hz, and 1 cent becomes 0.5233Hz
G#/Ab = 830.61Hz
A = 880hz
therefore 100 cents between A and G#/Ab = 49.39Hz, and 1 cent becomes 0.4939Hz
This is why it is dangerous to use ideas like 1200 cents in the octave as the cent ends up being miscalculated - in the octave 220Hz to 440Hz this would set the cent to something like 0.1833Hz which is significantly larger than the cent between A=220Hz andf A#/Bb=233.08Hz, 0.1308Hz difference is 0.0521Hz
