Reply to comment by IMKGI in ANC app for generic ‘phones use? by minnesotajersey

Then how does the bloody signal get picked up by my neckbuds’ mic, processed through the ADC, processed by the DSP, processed through the DAC, sent through the amp, and into the drivers without said latency issues?

As you probably know, ANC headphones aren't the best sounding devices out there, they are very likely trading processing time for speed to achieve desired results, the DAC and amp in a pair of ANC headphones are nothing like the one in a regular phone or headphone, but if you are interested in a DIY project I found this PDF: https://www.google.com /url?q=https://courses.physics.illinois.edu/phys406/sp2017/Student_Projects/Spring12/Danylo_Hirnyj_P406_Project_Report_Sp12.pdf&sa=U&ved=2ahUKEwj2jvSVrLv7AhWoXvEDHU24AGQQFnoECAQQAg&usg=AOvVaw05PJIiwqh6tUowxQ6KcHvZ Of a guy attempting to build a pair himself (Remove the space in the URL, it's before the / after www.google.com, Reddit blocked the original link)

The same way audio interfaces can offer "zero-latency" monitoring that would typically suffer from lag if the input needed to be routed to the phone/tablet/pc and back out.
