Stem mastering online – for streaming, CD & vinyl

 A Stereo Master It's perfect when you're 100% satisfied with your mix and the balance (e.g., between vocals and beat) is already perfect.

A stem mastering We recommend group mastering if you're unsure or want to get the absolute best results. Since you provide us with 4-5 group tracks (e.g., drums, bass, vocals, and instruments separately), we can address complex issues that would be impossible with stereo mastering – for example, if the vocals get lost in the chorus or the bass clashes with the kick drum. If you're still unsure, feel free to use our [service/tool/etc.] beforehand. Mix analysis in which we'll tell you what you can improve in the mix and which form of mastering you should choose.

The direct comparison:

Stem mastering offers you the opportunity to specifically influence individual components of your mix – without having to go back to mixing This allows, for example, better separation of kick and bass, or adjustment of vocals in relation to the music. The sound becomes more precise, transparent, and competitive.

Because we have access to 4-5 group tracks, we can fix problems that would be unsolvable in normal mastering. We use techniques like EQ, compression, and saturation specifically for:

• Perfect balance: Are the vocals in the chorus too quiet or the snare too loud? We'll correct the volume levels without affecting the rest of the song.

• Clarity & Separation: When instruments and voice clash in terms of frequency (masking), we create space and transparency.

• Analog Heat & Pressure: For example, we can give the drums more analog punch while keeping the vocals airy and open.

• Stereo width: We make the mix wider and more spacious without the kick drum losing its punch in the middle.

How do I deliver the stems? (Checklist) In order for us to perfectly process your stem mastering, we need your files in the following format:

• Format: WAV or AIFF (at least 24 bits, ideally at the sample rate of your project).

• Synchronicity: Important! Export all stems from the exact same starting point (0:00), even if no sound is audible at that point. This ensures all tracks remain synchronized.

• Master bus: Please turn off all effects on your master channel (sum) (no limiter, no compressor).

• Single tracks: You can leave creative effects (reverb, delay) on the groups enabled, provided they are part of the sound.

• Designation: Label the files clearly (e.g., "Drums", "Bass", "Vocals", "Instruments").

Artists typically submit 4–8 stems. Common subdivisions are:

• Drums (including overheads)

• bass

• Kick separately (optional)

• Gitarren

• Synths or strings

• EFX (effects, Atmos)

• Vocals (lead, backings, harmonies)

• Samples or special instruments

This distribution can vary depending on the genre or arrangement. It's important to remember that similar sound sources should be grouped together (e.g., all backing tracks or all strings in one stem).

• Too many or too few stems: The goal is balance. 4–8 is usually ideal.

• No level adjustment: Unbalanced stems make mastering more difficult.

• Unsynchronized starting points: All stems must start at 0:00.

• Clipping or limiting on the stem: Please leave unedited.

• Mixing inappropriate elements in a stem: e.g. bass + vocal is problematic.

The processing time is expected within 3-7 working days after receipt of payment – ​​depending on the scope, number of stems and desired revision depth.
For fixed deadlines we offer a prioritized express processing
