Data from sound spectrum experiment

[maozekun]

Hi, the experiment given by the first QR code can only give 4801 data, and the second QR code display has no output item set. It seems there are some problems...

Both work flawlessly for me, giving 720000 lines of data… hm.

Which platform and OS version are you using? Possibly it could be a performance issue on non-recent mobiles.

My mobile phone is Huawei mate10, Android system.

Let me tell you about my operation process. I used the scanning QR code of phyphox to add the experiment, timed and recorded the audio for 15 seconds, and then exported the Excel data to my wechat (our chat tool), showing only 4801 data.

By the way, in CN we are not able to use google store, so i'm not sure if there's a problem with my version.
