I wanted to create a scrollbar(pyqt5) into tab, base on example in link below I did some changes to fit my need but the scrollbar didn't show on tab and my charts become smaller.

example PyQt4 - how to add scrollbar into tabbed windows of fixed size?

I don't quite understand how reference counting is done with memoryviews in large/longer nogil sections. Let's assume basically all my code is nogil, except for the creation of a numpy-array-to-memoryview deep down. The memoryview is returned and used upwards.

A fairly simple example would be

I have a large quantity of .wav files that I need to analyze using the acoustic indices from the "soundecology" package in R. However, the recordings do not have uniform start times and I need to analyze specific periods of time within the files. I want to create a function and loop for automating the process. I have created a spread sheet for each folder of recordings (each folder is a different location) that lays out the recording and the times within each recording that I need to analyze. Basically, a row contains: the sound file name, the time when the sample should start (eg. 09:00:00, the number of seconds from the start of the file that that time occurs, and the munber of seconds from the start time of the file that the end of the sample should occur. That data looks like this: Spread sheet of data

I am using the package "tuneR" and "warbleR" to select the specific portion of a sound file that I want to analyze. Here is the the code and the output that I would like to loop across all the sound files:

wavrow1 <-read_wave(mvb$sound.files[1], from = mvb$start[1], to = mvb$end[1]) wavrow1.aci <- acoustic_complexity(wavrow1, j=10)
