Music and Acoustics 
From Instrument to Computer

How can a piano tuner obtain such high precision with no other
measuring device than their own ears? How can a sequence of notes
seem to rise continuously despite coming back periodically to the
same notes? What are the possibilities and the limits of digital
sound? These are a few examples of questions that are discussed in
this book, which presents an overview on the nature of musical
sounds, from their production by acoustic music instruments to
synthesized sounds obtained with computers.

The topics that are treated include sound propagation, Fourier and
time-frequency analysis, psychoacoustics, analog and digital signal
processing theory, computer science and MP3 sound compression, and
of course… music!
