What is production? Part 1: A&R

If you spend a lot of time reading and viewing videos about professional audio on the Internet, then you could easily get the idea that production is all about having the right equipment and software, particularly plug-ins.

A brief introduction to mastering in the home recording studio

A brief introduction to mixing in the home recording studio

The function of mixing has changed since the beginning of the modern era of recording techniques in the late 1960s.

But as multitrack recorders developed, eventually it was possible to place each instrument and vocal on its own track, and leave the mixing until later.

It is also used to improve the mix, and to make tracks on an album flow seamlessly from one to another without sudden changes of frequency balance.
