Spectrum-based analysis and synthesis of percussion sounds
James W. Beauchamp · The Journal of the Acoustical Society of America · 2004
From the standpoint of the listener, convenient ways to catagorize percussion sounds are in terms of mode frequency positions, mode frequency spacing, and decay rates. Some sounds, like those of bells, chimes, and other struck bars, have modes which are widely spaced. Other sounds, such as those of timpani, tam-tam, and cymbals, have many more closely spaced modes. Measurements of average modal spacing, time-varying spectral shift, spectral incoherence, attack time, and decay rate are presented for a variety of percussion instrument sounds. Examples of percussion synthesis using this information will be presented.
