As a way of improving the results of the FFT based analysis and synthesis of digital sound, some researchers applied high resolution analysis combined with a model which attempts to represent the attributes of a sound taking in account its deterministic and stochastic parts(see Serra and Smith, 1990, and Pampin, 1999). This paper deals both with the ATS (analysis, transformation and synthesis) technique and with a graphic application developed to handle it, the ATSH program.
