Audio DAC vs. general purpose DAC (or ADC for that matter)

[chrome]

So as the title says, what is the difference between the two? Seeing as there are huge price gaps between the 2 kinds.

DC accuracy comes to mind. This looks like a good article on the topic: http://electronicdesign.com/article/analog-and-mixed-signal/should-you-use-audio-adcs-for-precision-applications-

sample rates, audio is quite slow compared to most data busses, even an 192kHz Codec will often have anti aliasing filters set at 22kHz, limiting the bandwidth you can capture. An as said above, most have DC blocking caps, look for "DC coupled" if you do not want a codec with an integrated capacitor.

Really it comes down to what type of signal you want to acquire.

I think that the low-pass scales with the sampling frequency. At least on PCM1792A datasheet:
