Stem

A stem in podcasting refers to an individual audio track in a multi-track recording. Each stem contains a separate element of the podcast, such as vocals, music, sound effects, or background ambiance. Stems are used during the editing and mixing process to adjust the levels, apply effects, and ensure that all elements blend together seamlessly.

Using stems allows for greater control and flexibility in post-production, enabling editors to fine-tune each component of the podcast independently. This results in a polished, professional final product. Stems are particularly useful for complex productions with multiple audio sources, ensuring that each element is balanced and clear.
