Mastering, a form of audio post-production, is the process of preparing and transferring recorded audio from a source containing the final mix to a data storage device (the master); the source from which all copies will be produced (via methods such as pressing, duplication or replication). Recently digital masters have become usual although analog masters, such as audio tapes, are still being used by the manufacturing industry, notably by a few engineers who have chosen to specialize in analog mastering. Mastering requires critical listening, however, software tools exist to facilitate the process. Results still depend upon the accuracy of speaker monitors and the listening environment. Mastering engineers may also need to apply corrective equalization and dynamic enhancement in order to optimise sound translation on all playback systems. It is standard practice to make a copy of a master recording, known as a safety copy, in case the master is lost, damaged or stolen.Audio Mastering. n.d. In Wikipedia.

Stem-mixing is a method of mixing audio material based on creating groups of audio tracks and processing them separately prior to combining them into a final master mix. Stems are also sometimes referred to as submixes, subgroups, or busses. Some people consider stems the same as separation mastering although others consider stems to be sub-mixes to be used with separation mastering. There is some lack of clarity with regards to what is a stem versus what is a separation. Semantically it seems to depend on how many separate channels of input are available for mixing and/or at which stage they are at towards reducing them down a final stereo mix, with different people drawing the separation line at different places. This technique originated in the 1960s with the introduction of mixing boards that were equipped with abilities to assign individual inputs to sub-group faders and then manipulate each sub-group (stem mix) independently from the others. This technique is widely used in recording studios to control, process and manipulate entire groups of instruments such as drums, strings, or backup vocals, in order to streamline and simplify the mixing process. Additionally, as each stem-bus usually has its own inserts, sends and returns, the stem-mix (sub-mix) can be processed independently through its own signal processing chain to achieve a different effect for each group of instruments. This technique is also practiced with DAW in a similar way where groups of audio tracks may be processed and manipulated digitally through a separate chain of plugins.Stem mixing and mastering. n.d.

Stem-mastering is a technique derived from stem mixing. Just like in stem-mixing, the individual audio tracks are grouped together to allow for independent control and signal processing of each stem and can be manipulated independently from each other. Even though this method is not commonly practiced by mastering studios it does have its proponents..Stem mixing and mastering. n.d. In Wikipedia.
