Recording at a studio consists of aspects such as recording audio, equalization, mixing and mastering audio. In this field, there are 3 types of working methods. They are Digital, Analog and Hybrid systems. In digital systems, normally a computer with a digital audio workstation (DAW) is used. A digital audio workstation is a software that allows dealing with audio signals. Examples for most popular DAWs are Cubase, Ableton Live, FL Studio and Protools. By using DAWs, audio engineers can affect audio in many paths such as applying effects to audio signals, compressing audio signals, mixing, mastering, creating new audio signals and recording. In these audio productions, engineers use plugins called VST plugins. These VST plugins are created in most popular studios in the world which have a good environment to record sounds. And the instruments are played by popular and talented musicians. These VST plugins are user-friendly and we don’t need instruments to record its sound. The quality of these digitally produced sound is relatively inferior compared to the sound produced by using analog systems. Reasons for that difference is due to the machines that add different harmonics to the sounds. But it is costly to produce audio by using analog systems. The other type is hybrid production. It is a combination of both digital and analog systems. Quality sounds than digital production can be obtained by hybrid production. Above factors are the main uses of audio engineering in the music field. In the music production field other than the song production, there are factors such as film music production, music production for advertisements, etc. In the past, it was very difficult to produce a song as all the instrument players had to play together to take the recording. If one player made a mistake, all players had to play and record the whole song again. As a result of the development of audio engineering today, it has become much easier. Today instruments record individually and then they are mixed to get the whole song. If a player made a mistake, instead of recording the whole thing again, the mistake can be edited and corrected properly by the technology Generally, in the current context, many music lovers go forward to experiment and learn about this emerging field of audio engineering. Lots of new equipment and technology is getting invented as well. Therefore, the field of audio engineering is developing rapidly along with the quality of sound Vishwa Abeywardana, First year undergraduate, Faculty of engineering, University of Peradeniya.
