Stem mixing is an advanced approach that provides additional control and flexibility in the final stages of music production. It involves working with separate groups of audio tracks known as stems, which consist of grouped elements such as drums, bass, vocals, synths, and more. Stem mixing allows for more precise adjustments and enhancements to each individual element of your song. In stem mixing, the audio tracks are grouped into stems, enabling the engineer to apply specific processing and mixing techniques to each stem independently. This approach grants greater control over the balance, EQ, dynamics, and effects of individual elements within the mix, resulting in a more refined and polished sound.
