> There are precisely zero 32 bit ADCs in existence. > There are ADCs that will provide 32 bits per sample but that's entirely different. Now that requires elaboration. There is e.g. AD's LTC2500 (https://www.analog.com/en/products/ltc2500-32.html https://www.analog.com/en/products/ltc2500-32.html). Not meant for audio (too slow at 32b) and not noise free, but it's a bona-fide 32b ADC. Now there might be no ADC which provides 32b wide noise-free samples at sample rates needed for audio and given the absurdly low level of a LSB signal that might be as infeasible as it would be pointless, but that's a bit of a different statement.
