WHAT IS THE EFFECT OF AUDIO QUALITY ON THE ROBUSTNESS OF MFCCs AND CHROMA FEATURES?
"... Music Information Retrieval is largely based on descriptors computed from audio signals, and in many practical appli-cations they are to be computed on music corpora contain-ing audio files encoded in a variety of lossy formats. Such encodings distort the original signal and therefore may af-fect th ..."

-fect the computation of descriptors. This raises the ques-tion of the robustness of these descriptors across various audio encodings. We examine this assumption for the case of MFCCs and chroma features. In particular, we analyze their robustness to sampling rate, codec, bitrate, frame size and music genre. Using two
