From wikipedia:

"A mix engineer or mixing engineer is a person responsible for combining ("mixing") the different sonic elements of a piece of recorded music (vocals, instruments, effects etc.) into a final version of a song (also known as "final mix" or "mixdown"). He or she mixes the elements of a recorded piece together to achieve a good balance of volume, while at the same time deciding other properties such as pan positioning, effects, and so on."

"A record producer is an individual working within the music industry, whose job is to oversee and manage the recording (i.e. "production") of an artist's music. A producer has many roles that may include, but are not limited to, gathering ideas for the project, selecting songs and/or musicians, coaching the artist and musicians in the studio, controlling the recording sessions, and supervising the entire process through mixing and mastering. Producers also often take on a wider entrepreneurial role, with responsibility for the budget, schedules, and negotiations.

Today, the recording industry has two kinds of producers: executive producer and music producer; they have different roles. While an executive producer oversees a project's finances, a music producer oversees the creation of the music.

A music producer can, in some cases, be compared to a film director, with noted practitioner Phil Ek himself describing his role as "the person who creatively guides or directs the process of making a record, like a director would a movie. The engineer would be more the cameraman of the movie."[1] The music producer's job is to create, shape, and mold a piece of music. The scope of responsibility may be one or two songs or an artist's entire album – in which case the producer will typically develop an overall vision for the album and how the various songs may interrelate."
