Hi! I am studying the Audio interface. In fact, I have had some issue. I can't understand what the meaning for those vocabularies, Low Frequcy Enhancement Channel, Latency and PCM. Does anybody know where I can find those meaning or explainatio? TKS.
 

Audio description is a term used to describe the descriptive narration of key visual elements in a video or multimedia product.

sorry I read the title and answered. pls next time try to find a better title.
 

pcm phase code modulation
and channel means that it will improve the data tranmission at low frequencies
 

PCM = pulse code modulation, it is a way of converting analog signals to digital ones

Latency is the length of time it takes to process an analog signal to digital and then back to analog
