I have computed 12d-MFCC features on 3 consecutive audio frames, say:
For 1st frame: a1 a2 a3 ... a12 For 2nd frame: b1 b2 b3 ... b12 For 3rd frame: c1 c2 c3 ... c12
How to organize these MFCC features, in
a1 a2 ... a12 b1 b2 ... b12 c1 c2 ... c12 or
a1 b1 c1 ... a12 b12 c12? Is there any difference between these two organization styles (for audio processing)?
