what are Multi track-outs
"Track-outs" of "Multi-tracks" are the recorded separate, individual elements of an audio production. For Example, Kick, Snare, Main Vocals etc etc. Some may be mono, while others are stereo. They may have been recorded from microphones or direct inputs, programmed in a sequencer, or arranged in a sampler. In many cases, time-based effects such as delay and reverb are excluded to allow flexibility for the mixing engineer.
what are STEMS
Stems or "Group Stems"are stereo recordings sourced from mixes of multiple individual tracks. For example, a drum stem will typically be a stereo audio file that sounds like all of the drum tracks mixed together. In most cases, additional processing such as equalisation, compression, and time-based effects is included to ensure that the sound achieved by the mixing engineer is committed.
