Both the engineers and sound recorders had to utilise their listening skills to distinguish the pure tones and random noises and to estimate the frequencies of sound. There were various complex and simple sounds which the judgement had to be made. There was requirement of technical capabilities so that the respective changes could be made and the quality of sound would be improved. There had to be professionalism in carrying out their tasks so that the recordings are synchronised with the performance (Brackett, 2000). Since there had been a lot of technical advancements, these artistic directions to be given by the producers were improved. The sound engineers are responsible for making suitable choices of sounds by listening to the request of the musicians. Thus, the key skills required for any ideal producer would be communication and interpersonal skills. The outcome of all the efforts is dependent on capability of the sound producer to know, rate and change a range of parameters of music performances, the compositions and schedules along with the quality of the sound. It is important that record producers systematically look for diverse technical and artistic prospects by critically listening and experimenting. It is similar to the performers in the way they practice regularly with their instruments. By doing so, they can create flexibility which is required for proposing different choices which are most apt for every situation. There had to be critical listening skills in order that the adaptation is there towards diverse musical genres. Not only there is the need for adjustments, but also there is a need to learn the way of using new tools. Every time these engineers worked in a different location or a different situation. With the changes in the technology, they had to adjust accordingly, thus they are required to process the flexibility skills.
