In other languages (e.g. Python and R), packages for reading EDF files typically include the capacity to extract the sampling rate of a signal. This doesn’t seem to be possible in the [EDF.jl package](https://docs.juliahub.com/EDF/a8X2Z/0.7.4/). My two questions are: a. am I missing something in the package’s documentation? If not, b. what other ways are there to infer the sampling rate of a signal?
_Note_. Reading the EDF does not produce a _Time_ vector (from such vector one could infer the sampling rate).

You have to calculate the sample rate on your own, I guess - you have `seconds_per_record` in the `FileHeader` and `samples_per_record` in the header of each signal, so dividing the latter by the former will give you samples per second.
