Ran in:
This is interesting!
The online Run feature computer uses Linux, and gives this result:
ZF = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/880055/VEHCar_Acceleration%20aston%20martin%20(ID%200600)_BSB.mp3.zip';
UZ = unzip(ZF);
ai = audioinfo(UZ{1})
ai = struct with fields:
Filename: '/users/mss.system.cVYhtd/VEHCar_Acceleration aston martin (ID 0600)_BSB.mp3' CompressionMethod: 'MP3' NumChannels: 1 SampleRate: 48000 TotalSamples: 315600 Duration: 6.5750 Title: [] Comment: [] Artist: [] BitRate: 320
[s,Fs] = audioread(UZ{1});
s_len = numel(s)
s_len = 314496
Windows 11 (run offlilne with the same code with R2021b) gives the following:
ai =
struct with fields:
Filename: 'C:\Users\vitha\Documents\MATLAB\FEF_Files\R & D\Answers & CSSM Problems\Temporary Projects\VEHCar_Acceleration aston martin (ID 0600)_BSB.mp3'
CompressionMethod: 'MP3'
NumChannels: 1
SampleRate: 48000
TotalSamples: 314496
Duration: 6.552
Title: []
Comment: []
Artist: []
BitRate: 320
s_len =
313968
I don’t have access to a Mac, so I have no idea what result it would give.

Yes, for me using MATLAB is much easier so that I can analyse multiple signals within MATLAB environment.
Thank you once again @Star Strider for the help!
