Echo on Macbook Pro when using Logitech C920

[tao siping]

Hi Experts,

Do you notice the similar problem when using the microphone of Logitech C920 on Macbook Pro?

I checked the recorded audio files, and found that Near is ahead of Far (non-causal). Then I checked the system delay in the capture thread, found that _captureLatencyUs was very big, over 500ms.

Do you know why _captureLatencyUs is so big for C920 on Mac?

Thanks,

Siping

Interesting. I've seen this too, but assumed it was an environmental issue.

Can you create a bug and attach your audio files?

Hi Justin,

I can reproduce this issue 100%, I think you can reproduce it too with Macbook Pro and C920.
