== Voice Generator ==
6.4ms per repeat (noise and pause), or
9.1ms per repeat (tone with pitch=91)
Note: Some speech interfaces have the chip overclocked to 4MHz, resulting in higher pitch & sample rate, and shorter timings as with the normal 3.12MHz.
== Amplitude/Pitch/Repeat ==
Above shows only positive values for index 0..127. Values for index -1..-128 should be 0..-511, or maybe -9..-512.
