Re: [LAU] Linux Synchronization of multiple audio channels e.g. for exact processing of ( timing ) differences between channels

Hello to users of the various Linux sound systems! I have a rather technical question regarding the implementation of multichannel recording and playback : Is the relative alignment of different channels exactly constant? I mean, can I reliably assess ultra short differences between multiple channels, e.g. if one channel's signal is a delayed signal of another channel by about 700 ns and I want to calculate the exact delay of the signals relative to each other? I'd also need to pass exactly timed signals to the outputs. Internally for the inputs and outputs I would probably choose a platform with I2S, but other embedded protocols would be alright too, if I can match them to the ADCs chips outputs and DACs chips inputs. So what I need to know is not about the delay from input to output, but rather how well and exact the synchronization of multiple channels works. I would be happy about hints and answers.
