Matlab incorrectly reading in number of samples?

I have a program that processes a large number of audio files, all exactly 48k sample rate and 48k total samples. All files get read in with no problem apart from one. I have checked that it is exactly 48k samples in both REAPER and ProTools and they both show that. However, in MATLAB it gets read in at a different value and causes the code not to work.

Is there any way too solve this as I cannot think of a reason why that one specific file which is identical to all the others is not being read in at the correct total sample value.

You will probably not get any useful help with this unless you attach the "bad" file and one of the "good" files.

My apologies, 6000 P3 is a file that reads in with the correct number of samples and 6000 P4 reads in incorrectly.

audioreader() gives 48000 x 2 for both files for me. Which function are you using to do the reading or querying?

unzip('Files for analysis.zip')
X = audioread('Files for analysis/6000 P3.wav')

X = 48000×2
