Estudo do impacto na qualidade de gravação por meio da utilização de diferentes cabos

Abstract

This paper presents a study of the difference of voice, acoustic guitar and White Noite audio recordings characteristics, due to modification of the cables (Volcano and Hayonik) of the microphones (dynamic and condenser) used for recording the same audios after being played by hifi equipment, recaptured and stored via a specific software. It provides basic theories about the physical phenomens in the present work, digital recording, the recording techniques, and technical specifications of the materials used for the work. It brings the spectrum analysis waveform of each recording, differences in levels presented by modification of cables and also some differences in the waveforms. It also raises up technical data of cables cited - resistance and inductance in series and capacitance and conductance in paralel. It presents professional opinion of the subject, so that we can complete the work with data based on everyday experiences used for professional audio applications.
