This term refers to changes of a sound waveform which occur in electroacoustic systems. Problems in an electroacoustical system which produce distortion are the following: the inability to maintain linearity, resulting in the addition of unwanted harmonics; the inability to pass the complete audio spectrum equally; the inability to handle transients; the inability to pass all signals in the same amount of time.

In electroacoustic music and some kinds of modern popular music, distortion is exploited for musical purposes. The composer may alter the waveform of the original sound by various modulation techniques. Rock groups often create distorted effects by means of feedback or by overloading the amplifiers and speakers. (reduced from Barry Truax - Handbook for Acoustic Ecology CD-ROM Edition.

Ce terme désigne les modifications de la forme d'onde d'un son telles qu'elles sont produites dans les systèmes électroacoustiques. Un système électroacoustique peut produire des distorsions dans les cas suivants : impossibilité de maintenir la linéarité du signal ce qui ajoute des harmoniques non désirées, impossibilité de transmettre l'intégralité du spectre, impossibilité de gérer les ruptures, impossibilité de transmettre l'ensemble du signal dans un même laps de temps.

Dans la musique électroacoustique, de même que dans plusieurs types de musiques populaires modernes, la distorsion est exploitée musicalement. Ainsi, le compositeur peut modifier la forme d'onde du son original par diverses techniques de modulation. De même, les groupes de rock utilisent souvent les effets de distorsion comme le feedback ou la surcharge les amplificateurs et des haut-parleurs.

Con tale termine si fa riferimento alle modifiche della forma d'onda di un suono prodotte dai sistemi elettroacustici. Un sistema elettroacustico può produrre distorsione nei casi seguenti: quando è impossibile mantenere la linearità del segnale, nel qual caso si producono armoniche indesiderate; quando è impossibile trasmettere l'integralità di uno spettro; quando è impossibile gestire i transienti; quando è impossibile trasmettere l'insieme dei segnali nello stesso lasco di tempo.

Nella musica elettroacustica, ma anche in molti tipo di popular music, la distorsione è sfruttata musicalmente. In questo modo, il compositore può modificare la forma d'onda del suono originale attraverso varie tecniche di modulazione. Nel rock si usa spesso l'effetto di distorsione, come il feedback o il sovraccarico degli amplificatori e degli altoparlanti (Fonte – ridotto da Barry Truax - Handbook for Acoustic Ecology CD-ROM Edition.

Este término se refiere a los cambios de la forma de onda de un sonido que ocurran en un sistema electroacústico. Los problemas en un sistema electroacústico que pueden producir distorsión son los siguientes: la incapacidad de mantener la linealidad, resultando en la suma de armónicos indeseados; la incapacidad de dejar pasar el espectro de audio completo sin alteración; la incapacidad de manejar los transientes; la incapacidad de dejar pasar todas las señales en el mismo lapso.

En la música electroacústica y algunos tipos de música popular moderna, la distorsión es explotada con propósitos musicales. El compositor puede alterar la forma de onda del sonido original mediante diversas técnicas de modulación. Los grupos de rock frecuentemente crean efectos de distorsión por medio de la realimentación o sobrecargando los amplificadores y altavoces.
