Can "audioread" read mp3 file correctly?

I use the code

[y,Fs]=audioread('**.mp3','double');

to read a mp3 file. and size(y) is [12762480 2] (two channels).

But foobar tells me that the sample is 12 759 666. They are different, which one is correct?

The variation could be due to the limitation highlighted here. There are instances when the software and hardware specifications also play a role in how many samples would be output when ‘audioread’ is called. This can be mainly attributed to MP3 compression not having a fixed bits per sample ratio. However, this does not mean that the samples are incorrect. The sound function can be used to verify if the original audio is still intact.

Hope this helps!
