Read in an audio file, calculate the entropy using default parameters, and then plot the results. [audioIn,fs] = audioread( 'Counting-16-44p1-mono-15secs.wav' ); entropy = spectralEntropy(audioIn,fs); t = linspace(0,size(audioIn,1)/fs,size(entropy,1)); plot(t,entropy) xlabel( 'Time (s)' ) ylabel( 'Entropy' )

It is worthwhile to consider the theoretical limits for the minimum number of bits required to represent an audio sample. Shannon, in his mathematical theory of communication [Shan48], proved that the minimum number of bits required to encode a message, X, is given by the entropy, He ( X ). The entropy of an input signal can be defined as follows. Let X = [ x1, x2, … , xN] be the …

transmitted data bits, which gives us more compression of the stored audio file. There are several types of entropy coding. Some of the commonly used ones are Huffman coding, Arithmetic coding and Rice coding. For our coder, we have used Huffman entropy coding.

I then use the non permuted compressed file size and divide twice by two to get a conservative entropy rate. This method seems to be as good as any, and more robust that most. I estimate about 1.6 bits / byte from a 24V Zener diode at 10kSa/s. That's 16kbps of cryptographic strength entropy.

that stores the values of the entropy signal as an AFP ( gures 2a and 2b). The entropy signals are almost identical when comparing the original song and its louder version disregarding the vertical shift ( gure 2c). Equalization does deform the entropy signal ( gure 2d), however, the position of local maxima and minima seems to be the
