The scientific article analyses engineering (applied) practices of computer sound editing based on the Audacity® software package. Key element of the analysis are the processes of adjusting smooth interval transitions of spectrum-frequency amplitude of audio signal from the state of low frequency potential is increased and vice versa when computer editing of audio recordings. The main tool for adjusting the audio signal is Nyquist programming language. Subject area of the article addresses the problem of improving the quality of processing fragments of audio material subject to various types of smooth direct polar fading and crossfading (including both polar and crossfading modulation of audio signal) based on the in-program capabilities of the Audacity® audio editor, including its terminal control via NyquistPrompt. The article summarizes and reveals the enormous potential of accurate computer editing based on freely distributed software and improves the existing engineering approaches to the processes of fading and crossfading. Strategies for using the Nyquist language programming code as a special ultra precise tool organically following-up the traditional interface-oriented program options are justified. An important role of the processes dealing with control and management during the routine operations in the field of applied audio engineering that contribute to the improvement of general engineering approaches that ensure timely solution of tasks is assigned in the article too.
Keywords:computer processing of audio material, spectrum-frequency amplitude, fading, crossfading, Audacity®, Nyquist, NyquistPrompt.
