Description
How it works:
For example, you have chosen the “gold package” which already includes 10 stems or multitracks if you need 40 stems or multitracks in total just add an additional 30x stems or tracks for the gold package, and you are set.
What are multitracks?
Multitracks are the recorded separate, individual elements of an audio production. 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, dynamics processors such as compressors and time-based effects such as delay and reverb are excluded to allow flexibility for the mixing engineer. The image below shows a folder of multitrack.
What are stems?
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 equalization, compression, and time-based effects is included to ensure that the sound achieved by the mixing engineer is committed. The image below shows a folder of stems generated from a mix of the multitrack files displayed in the previous image.
