[sdiy] DACs on-board 12 vs external 16 vs 24 bit

[Justin Owen]

Hello,

For a digital, micro-based oscillator (being used in a modular environment if that makes a difference) outputting the standard one waveform at a time sine, triangle, saw, pulse waveforms between e.g. 0.1 Hz and 20KHz (probably closer to a max of 10KHz) with the regular features of hard sync, FM, PWM, Unison etc.

...how much difference is the average human going to hear between 12, 16 and 24 bit DACs?

For extra reference - I'm looking specifically at the 12-bit DACs on the STM32F407xx vs. the option of an external DAC of some sort.

Thanks.
