Hello, I have read the job description that you offer. I am very interested in working on this project. I am sure that I can do it according to your request.
Technically, the process needed to improve the quality of your audio files is by editing, mixing, and mastering according to standards so that they are ready to be packaged into your music or audio. As an audio engineer, I can work on this project according to your request. You can see my portfolio.
As an audio engineer, I have a job description to do documentation and representation based on composition and arrangement in the context of overall music production. In this case, the audio engineer has a workflow that includes the stages of recording, editing, mixing and mastering for the purpose of achieving the final result of music production.
Hopefully I can help and serve what you need. Thanks.
