Basically, what a sound engineer needs to have if he desires to work in a recording studio or in an open or close door entertainment venues are:
1) Firstly, a sound engineer should definitely have a very good sense of hearing. This means that he or she knows how to distinguish between sounds – knows which one is flat or which one is out of tune and of course knows timing and rhythm as well.
2) Secondly, one should have a good sense of imagination and has the ability to interpret what a particular musical set-up a certain scene calls for – on top of the musical artist skills of interpretation in the case of an outdoor concert. The sound engineer should easily adapt to the needs of every situation he is confronted with, as his ultimate goal is to satisfy the needs of his audience.
3) Lastly, the sound engineer should be well trained or has experience in using, both in hands-on and in theory, in using all the equipment he or she has in his or her disposal in order to make a movie, musical video or a musical show very entertaining. It makes a great difference if the sound engineer is not only well-equipped but also knows well how to use his or her equipment, much more if all equipment are highly sophisticated one.
