i imported an .m4a audio file with following command: [yh fs]=audioread('background_noise.m4a').
Looking now in my workspace my data (yh) is stored as a 46080x2 double. Now i know that 46080 are my samples (nothing special) but I am wondering why my audio data is stored in two columns with slightly different values instead of just one column? I mean it is "just" an audio file, isn't it?
Can someone please tell me why that is and what information I get out of this?
I would be super happy for a quick reply/answer!
