Multitrack Mastering

Multitrack (Stem) Mastering Service – Professional Online Audio Mastering

Professional Multitrack (Stem) Mastering by LLOKKO Recordings provides advanced control over your final sound by mastering grouped stems instead of a single stereo file. This approach allows precise adjustments to balance, clarity, punch, and stereo image while preserving the original mix and artistic intent.

Stem mastering sits between mixing and stereo mastering. It is ideal when a track sounds close but needs targeted corrections that cannot be solved on the stereo bus alone. Your music will be optimized for streaming platforms, digital stores, club playback, and professional DJ use, following current industry standards.

What This Service Includes

• Independent processing of grouped stems (e.g. drums, bass, music, vocals, FX)

• Improved clarity, separation, and low-end control

• Enhanced punch and dynamics without over-processing

• Stereo image refinement and depth control

• Final loudness optimization and quality control

Multitrack (Stem) Mastering – Submission Instructions

To ensure the best results, please follow these guidelines:

• Upload grouped stems (not individual tracks unless agreed).

• All stems must:

  • Start at the same time (0:00 / bar 1)

  • Have the same length

• File format: WAV or AIFF.

• Sample rate: original project rate (44.1 / 48 / 96 kHz).

• Bit depth: 24-bit or 32-bit float.

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

• No clipping on any stem.

• Remove limiters, maximizers, and loudness processors.

• Keep creative effects essential to the sound (reverbs, delays, sound design).

• Use clear stem naming (e.g. Drums.wav, Bass.wav, Vocals.wav).

• Include a rough mix or reference track (recommended).

• Specify the genre, target platform, and any sonic preferences.

Incorrect stem preparation may reduce mastering quality or require revisions before processing.
