Sound Engineering

How sound is captured, shaped and delivered: microphones, the mixing desk, the room, the stage and the screen, from the physics of a vibrating string to a mix that sounds right on every speaker.

For: anyone who records music in a bedroom and wants to know why it doesn't sound like the records, anyone thinking of studying audio or music technology, musicians who want to talk to engineers, and every listener who has wondered what a mixing engineer actually does.

Shaped by audio and music-technology degrees such as the University of Surrey's Tonmeister (Music and Sound Recording), Berklee's Music Production and Engineering, the University of Miami's Music Engineering Technology and the AES (Audio Engineering Society) education guidelines; told worldwide, from Abbey Road and Motown to Kingston dub studios, Lagos, Bollywood and Latin American live sound.

Study it in depth, for free

These pieces give you the intuition. To learn the major properly, these are the courses and texts universities use, free to read or audit, and the standard textbooks if you want to own one. Links checked November 2026.

The whole major, free: No university publishes a full free audio-engineering degree, so the best free route is MIT OCW 21M.380 Music and Technology: Recording Techniques and Audio Production as the spine (microphones, mixing, mastering, DAWs), with the acoustics, signals-and-systems and sound-design courses below filling Years 1, 2 and 4 around it.
