The article discusses general applied issues of computer audio synthesis based on Audacity® audio processing software. The suitability of application of major standard modules aimed at playback and generation of synthesized audio fragments in order to improve quality of the applied procedures when reproducing new audio forms obtained as a result of additive and subtractive types of audio synthesis is emphasized. Step-by-step actions of the application of audio synthesis modules corresponding to specific problem situations are developed. The circuits of regular modules of audio synthesis reproduction used in interface-oriented type of sound processing are schematically demonstrated. The issues of program – oriented approach to sound synthesis by using built-in Nyquist program language are mainstreaming. Some Nyquist scenarios touching LISP syntax are interpreted. The areas of Nyquist language application both at table-wave synthesis of sound and spectrum, frequency and amplitude modulations of audio signal are formulated. Program map of scenario actions emulation required when procedural editing of audio signal characterized as synthesized audio form is unveiled. General suggestions for improvement the processes of applied software based audio synthesis and software usage of macros, functions and some managing logical operators used in conditions of simulation design-modeling of sound as well are presented. Some listing and scenario expressions in Nyquist language used in designated specific individual cases of sound processing and helping to overcome many problem situations are thematically investigated.
