Sonar processing limits #67
Comments
Can you provide a screenshot and a description of the experimental setup? The sonar measurement is a bit tricky (and to be honest - if it had not been there since the beginning of phyphox I would no longer include it as a standard experiment) and there are two common problems: Could it be any of these? |
It was measuring the distance to a wall so I didn't need a ruler. Yes, the other issue was inconsistent results (i should see things being still or move away). The tablet i have can play and record sounds at the same time (used camera record and played a song) and the first heard would be through device or shortest path, missing measurements ought not be possible. I can play from two apps at the same time (if both do not want exclusive use), so could probably record twice in the same (if it must). So ramping is from a missed measurement? Couldn't it have a null input or use a copy of last if it missed something? My first concern was updating all graphs rather than just the ones on screen would slow it down and harm the results (I was looking at the echo-location tab), though graphs probably aren't that much burden though… This one is a Galaxy A11, dual mic. Which does it use? Video record: bottom mic is Left,top is Right, loudspeaker on bottom. Some devices have two speakers (the performance would vary between them and together could mar the results). |
My phone appears to be having troubles with showing data (screen updates slow and dis/reappearing or incomplete graphs).
I notice the first screen has history so this means all the graphs are running. There are no options so I cannot hide and disable pages…
