Reversing audio digits of audio object

My question is about reversing the integers of an audio object file’s data.

If I make an audio object, and I wish to convert the audio-data to integers between 0 and 10000, I then wish to access the effect of reversing the sequence of the audio integers.

Thus, if I were to take one audio sample, and the integer associated with it were 5691, the the reverse of this is 1965.

I need to apply this integer reverse function to ALL of the audio samples in my audio object, and when I tried on Mathematica, I get some error messages, and I sort of do not know what they mean exactly.

Please advise.
