Conventional music coders, based on a modified discrete cosine transform (MDCT) suffer greatly when lowering their bit-rate and delay. In particular, tonal music signals are penalized by short analysis windows and the variable length coding of the quantized MDCT coefficients demands a significant amount of bits for coding the harmonic structure. For solving such an issue, the paper proposes a frequency-domain...
Signals in animal communication are commonly judged as aesthetically appealing by human standards. This is particularly common for birdsong, often equated to musical compositions. No formal test, however, has analysed the harmonic properties of bird vocalizations. Musical intervals are based on the same physical characteristics of sound that underlie animal vocal signals. Thus, animals may use these...
