Splitting one channel into two using 2 into 1 stereo cable giving me ZERO lags ? help !
조회 수: 1 (최근 30일)
Now that I'm using two condenser microphone inputs to a single channel , I'm getting zero lags ! ? This shouldn't happen since I'm placing the two mics at quite a distance for audio localization . But still getting the same result and 89 degrees or 90 degrees angle each time ! Can some one share a better code of sound localization using generalized cross correlation on two condenser mics connected to your laptop? Please help! Since it is the only hurdle in my project. Even a correct algorithm or way to calculate angle from GCC information will help! Thanks!

A number of things could be happeninig here - low-end or built-in laptop sound cards most often have mono mic or line inputs (despite the drivers possibly suggesting otherwise). Are your acquired signals exactly identical or simply well-correlated in time? On the other hand, your cable may be a single stereo to 2x stereo instead of a stereo splitter. I suggest you check all those possible issues in isolation.
