upload stems for stem mastering

 

 

To ensure the best possible result, it’s important that your stems are properly prepared before sending them for mastering. Please follow the guidelines below:

 

1. Format

  • Export your stems as WAV or AIFF files in 24-bit or 32-bit float

  • The sample rate should be 44.1 kHz, 48 kHz, or higher – do not change the original sample rate

2. Stem Export

  • Export only the essential groups (e.g. drums, bass, vocals, guitars, synths, FX)

  • Avoid exporting every single track unless requested

  • Ensure all stems start at the same timestamp, even if some are silent at the beginning

3. Stereo Files

  • All stems should be stereo, unless the sound is clearly mono

  • Ensure proper panning within each stem (e.g. keep stereo width of background vocals)

4. Headroom

  • Leave at least -6 dB of headroom on each stem

  • No limiter or maximizer on individual stems or the master bus

5. Effects

  • Include creative effects (delays, reverbs, modulation etc.) if they are part of your intended sound

  • Do not include mastering-style effects like limiters or multiband compression

6. Naming

  • Clearly name each stem file, for example:
    _Drums.wav
    _Vocals.wav

7. Reference Mix & Tracks ( optional )

  • Include your final stereo mix as a reference

  • You may also send 1–2 reference tracks that represent the sound you are aiming for

8. Communication

  • Please include a few lines about:

    • What you’re hoping to achieve with the mastering

    • Any specific concerns or areas you’d like focus on

    • How and where the master will be used (e.g. streaming, vinyl, CD)

 

If you have any questions or need help exporting your stems,

don’t hesitate to get in touch.
