There are many types of audio engineering. Some of these types can be basic and easy to get a degree for while others take a lot of time and education to learn how to operate the equipment. Here are some of the businesses that might use an audio engineer:

Recording Studio. They would need an audio engineer to operate the microphones, mixers, software, and basically everything in the studio. This is a very good job for an audio engineer and they can earn some serious money and recognition working at a recording studio.
Auto Store. An auto parts store that sells stereo equipment will a lot of times have an audio engineer on staff to help assist in installations.
Home Audio Store. Audio stores will keep them on hand to provide the customer with assistance with what type of speakers to buy and how to install them. Sometimes they will even install the speakers for the customer at their home.

There are many schools that offer audio engineering degrees. However, a lot of these schools are not accredited. It is very important to make sure the school is accredited by an international accreditation organization before you attend classes there.

After you decide what school to attend you need to decide on what type of job you want to do. Coursework will vary depending on the type of job you wish to seek while becoming an audio engineer. The nice thing is that some companies will hire you while you earn your degree. This is because they know you are seeking a degree and they believe you will follow through and become a valuable asset to the business.
