Sound Engineering

Career Objectives

Design, develop and control sound.

Professional Profile

The sound engineer is responsible for the study of the sound phenomenon from its scientific, technological and artistic perspectives.

In the scientific aspect, he addresses the physical handling of sound in relation to its *acoustics and also as a pollutant.

In the technological aspect, he has competences in the *production and manipulation of sound in all its application areas.

In the artistic side, he approaches music as an artistic expression, where he has an important musical training.

Specific tasks or activities carried out in the profession 

He is in charge of the sound equipment of events and music bands. That is, to achieve a clear, pleasant sound with an appropriate volume, for that:

-He performs an acoustic conditioning of the place so that there is no echo that reduces the definition of sound.

-He creates *sound reinforcement in order to achieve a volume adequate to the size of the hall.

-He adjusts the equalizer, that is, he controls the obtaining of a good sound or *audible frequencies, giving more emphasis to certain frequencies, for instance, that the bass and drums sound more in a certain song, achieving a more pleasant sound.

He designs and creates the whole sound universe of public entertainment in terms of ambience, atmosphere and psychological and *semiotic variants of sound.

He addresses recording and sound reproduction techniques. For that:

-He agrees with the *producer or musicians about how they would like the final product to sound.

-He develops and designs the sound, contributing to the *composition and *musical arrangements.

-He has the responsibility to create a recording that meets the wishes of the producer, the artists and the band.

-The study of sound in terms of physics and the use of formulas that sustain it, allow him to adjust very precisely the parameters of the most sophisticated equipment and apply the most complex techniques.

He handles analogue and *digital *electronic technology such as: recorders, processors and players, each with a specific purpose:

Recorders store the sound in specific media.

Recording is the process that transforms the sound of the environment in voltage variations that can be stored in different ways.

The recording can be done through two alternative ways:

-Recording directly all the sounds in a single *track, where basically one or more musical instruments are needed such as a guitar or a *synthesizer, in addition to a good microphone to record the voices of a soloist or any other sound source.


Performing the multitrack recording method, which records multiple sound sources in *individual tracks so that the sounds can be processed and manipulated individually to produce the desired results.

The sounds of instruments and soloists’ voices are recorded in individual files, keeping exactly the rhythm and synchronization between them.

For instance, after recording some parts of a song, an artist can only listen to the guitar part, “silencing” all the tracks apart from that one.

If he wanted to listen to the voices isolated, he would mute the rest of the tracks.

If he doesn’t like the guitar part, or he found a mistake in it, and he wants to replace it, he just records that part again, instead of rerecording the whole song.

This is the common way to record music at present.

-Processors modify the sound.

Once the *recording of instruments and/or voices is finished, and the musicians are satisfied with the sound, the Musical production begins, which corresponds to the audio mixing of the multiple recorded tracks.

Here, audio signal processing techniques are applied to the musical production, making a *digital treatment of the signals through a microprocessor where through *software you can incorporate special sound effects such as *reverberation, choirs, echoes, etc.

The artist can apply an effect to a specific track and other effects to the rest or keep them in their original form or mix the different voices that make up a song according to his desire or add different instruments, etc. That way, the artist retains complete control over the final form of the song and also leaves open the possibilities to remixes in the future.


In the Mastering stage, the sounds are gathered and subjected to a joint optimization process to give the final form to the song. This is performed through computer techniques that brings together the voices and instruments previously recorded in the different tracks and redistribute them in the two *stereophonic channels, for its recording in the commercial industry.

Players play the sound as the voice, singing, instrumental music or sound effects.

The sound reproduction is a process that transforms the electrical signal into acoustic sound waves.

Good playback equipment (high fidelity) must meet a series of requirements to ensure that the sound reproduced and the original one are as similar as possible. The sound played must be free of noise and distortion.

He formulates engineering projects for the design of *sound devices.

He develops engineering projects that interact with other fields such as electronics and computer science.

He designs, installs, evaluates and supervises the operation of audio systems for TV programs or film shooting.

He performs *postproduction tasks both in films and television. In this, he carries out the edition of music, effects and dubbing, to then take all the sound elements and connect them to the final edit of the communicational piece.

He creates and adapts music for advertisements, radio and TV programs.

He designs, builds and develops engineering projects for the noise control and the internal acoustic conditioning of venues that require specific acoustic characteristics.

He advises musicians, architects and engineers.

He prepares venues for events or shows, identifying their acoustic problems and suggesting changes in their interior design or equipment changes.

He develops research in the Music Acoustics field.

He teaches in different areas of acoustics.

He advises on the evaluation of problems related to noise pollution and designs noise control solutions.

He performs Expertise for research.
