Spectral View Audio

1) horizontal vs vertical (time)
The user can switch between horizontal and vertical orientation of the time axis.
Maybe some students are used to the time axis being on the "x-axis".

Unfortunately, this is one of the things that cannot be added that easily. It can be changed using our experiment editor (https://phyphox.org/editor), but quickly adding a button that switches axes is a bit more complicated.

2) frequency scale linear vs logarithmic.
The user can swith between linear and logarithmic scale of the frequency axis.
This could be useful for lower frequencies.

For the color plot or for the "normal" spectrum? For the normal spectrum, you can switch after tapping the graph by unchecking the logarithmic scale in the "tools" menu. For the color plot, unfortunately, this again is a bit more complicated. The problem is, that we use our own file format to define the experiment layouts and we use this format to assemble the spectrum data in a format suitable for the color plot. This way, we can simply add color plots to almost any type of data, but this makes it also rather complicated to quickly change the way the data is arranged. At least for now the best solution to have a look at the lower frequencies is to tap the graph and zoom in. Unfortunately, the way we arrange the data also limits the resolution here.


So, both suggestions are great, but we will probably not change this right away as they require some work which we will first put into different features
