There are a few different paths you can take to become a recording engineer, though some are more likely to work for you than others. In general, you should strongly consider receiving a structured, official education in sound engineering and design from a technical school, college, or similar program. You can also potentially become a recording engineer by buying the equipment you need and teaching yourself to record and mix music and audio, though this can be quite difficult and will require a fairly large investment on your part. It can also be helpful to work as an intern for a recording studio as you are getting started.
To become a recording engineer, you should be sure you have a serious passion for music and audio recording. A recording engineer works with recording artists and studios to record, mix, and balance music and other audio. You typically need to have a strong combination of technical and musical skills and abilities to effectively hear the music being made and help refine it. This is also a technologically complex profession, and you need to be able to use computers and other hardware and software to become a recording engineer.
One of the most straightforward ways to become a recording engineer is to attend a school that offers a program in sound design or studio recording. This type of program may be offered by a technical school, though many colleges and universities also offer programs in sound design. You might also be able to find a non-traditional program in sound design, such as an online course or a program that uses a mentor-apprentice method. Whichever method you choose, you should ensure you attend a school that will provide you with the skills and knowledge you need to become a recording engineer.
You can also purchase the hardware and software you need to become a recording engineer and teach yourself what you need to know. This can be a difficult route to take, however, and you would need to make a sizable financial investment for the equipment. You are also unlikely to make the contacts that can be found while attending a school, which may make it more difficult to break into the industry.
Once you complete your education, then you should look for record studios in need of a recording engineer. You may need to work as an intern before being hired on by a studio, and if you are quite fortunate, you can find a master engineer willing to train you personally. It can be difficult to become a recording engineer, but proper preparation can make the process easier.
