1. Separation into Logical Groups:

- Identify the main elements of your mix to be separated into stems. Typically, these can include: drums, bass, vocals, guitars, synthesizers, effects, etc.;
- Avoid creating too many stems (4-8 is sufficient).
2. Checking:

- Ensure there are no unwanted noises, clicks, or other artifacts in each stem;
- Disable any processing on the master bus (limiters, compressors, equalizers, etc.);
- Ensure there is no clipping (overloads) on the channels, groups, and master section.

3. Naming Stems:

- Clearly and understandably name each stem so the mastering engineer can easily identify its content (e.g., "Drums," "Bass," "Lead Vocal").

4. Exporting Stems:

- Export each stem in WAV format with a sample rate of 44.1 kHz or higher and a bit rate of 24 or 32 bit;
- Export stems with the same start and end points to ensure synchronization;
- Make sure all "normalize" functions are turned off in your DAW during export.

5. Preparation for Sending:

- Create a text file with project information, including stem names, BPM, key, and any special requests or notes;
- Be sure to include your version of the mastering or your demo;
- Include 2-3 reference tracks;
- Place all prepared files in a ZIP archive.
