Stem Mastering for Absolute Sonic Control

Traditional stereo mastering is an art of subtlety, but sometimes a track requires more than just global EQ and compression. Stem mastering—also known as hybrid mastering—offers a middle ground between a full remix and a final master. By separating your mix into a few key groups (such as drums, bass, vocals, and instruments), we can address specific frequency clashes and dynamic issues that are impossible to fix once the track is bounced to a single file.

At Banaedgezen, our stem mastering process is designed for artists and producers who have a mix they love but feel it lacks that final "commercial" punch or spatial depth. Whether you are preparing a track for a club system, a cinematic release, or a streaming platform, we use our ATC and Genelec monitoring environment in Melbourne to ensure your stems are balanced with mathematical precision and musical intuition. This approach provides the flexibility to enhance the low-end without affecting the vocals or to add air to the high-end without introducing harshness to the percussion.

Stem mastering is an ideal solution for a variety of production scenarios where a standard stereo master falls short. First, it is essential for producers who find that their vocal is "buried" in the mix or that the kick drum is fighting with the bass synth. Since we have access to these elements separately, we can carve out space for each, resulting in a transparent and powerful sound.

It is also the preferred choice for electronic music producers and DJ-focused artists. In club environments, the relationship between the sub-bass and the kick is critical. Stem mastering allows us to apply multi-band processing specifically to the low-end stem, ensuring the track translates powerfully on massive sound systems without distorting. Additionally, independent labels often use this service to bring a cohesive sound to an EP where different tracks were mixed in different environments.

The process begins with a technical audit of your files. We don't just apply presets; we listen to the intent of the song. We examine how the drum stem interacts with the melodic elements. If the percussion is too dominant, we can attenuate it without affecting the harmony. This surgical approach allows us to enhance the "depth" of the mix, pushing some elements further back in the virtual space while bringing the lead elements forward.

Once the balance is established, we move into the enhancement phase. This involves using high-end outboard gear and precision plugins to add harmonic excitement. We focus on the "glue"—the process of making separate stems feel like a single, unified piece of music. Every decision is cross-referenced against our studio monitors to ensure that the master sounds consistent across different listening environments, from high-end headphones to car speakers.

To achieve professional results, your stems must be prepared correctly. We require files that are exported from your DAW without any master bus processing (no limiting or heavy compression on the output). This gives us the necessary headroom to work. According to our business rules, all stems should be at least 44.1kHz and 24-bit. We strongly recommend leaving a peak headroom of -6dB to avoid clipping during the upload process.

Common stem groupings include: 1. Drums/Percussion, 2. Bass/Sub, 3. Main Instruments/Synths, 4. Lead Vocals, 5. Background Vocals/FX. Ensure all stems start at the exact same time (zero-point) so they align perfectly when imported into our session. If you are unsure how to organise your files, we recommend reading our guide on online vs in-studio mixing to understand the technical requirements of remote collaboration.

Upon completion, you will receive a professional delivery package designed for immediate distribution. The primary deliverable is a high-resolution WAV file (24-bit) and a high-quality MP3 version for quick review. We provide a detailed loudness report including Integrated LUFS and True Peak values, ensuring you know exactly how your track sits compared to industry standards.

Depending on your needs, we can provide alternative versions such as an instrumental master or a "clean" version. Every project is backed by our commitment to quality; you receive a master that is technically flawless and musically enhanced. All files are stored securely for 6 months after delivery, giving you peace of mind should you need to request a minor adjustment for a different platform later.

Our average turnaround time is 5 business days. This period allows for the initial analysis, the actual engineering work, and a mandatory "ear-rest" period where we listen to the master with fresh ears the following morning. We believe that rushing the final 1% of a track is where most mistakes happen, so we adhere to a disciplined schedule.

For projects with urgent deadlines, we offer a rush fee of 30% over the standard price, which prioritises your project in our queue. Please note that the turnaround time starts from the moment we receive the correct files and the required deposit. We operate Monday to Friday from 10:00 AM to 7:00 PM (AEDT), with limited hours on Saturdays.

It is important to distinguish stem mastering from a full mix. We do not perform "mixing" tasks such as changing the volume of a single snare hit, replacing a synth sound, or re-recording a vocal part. If your mix has fundamental structural issues—such as a vocal that is completely out of tune or a drum loop that is off-beat—these must be corrected in the mixing stage before the stems are sent to us.

Additionally, our standard fee does not include unlimited revisions. We provide 3 rounds of revisions to ensure the master meets your expectations. Any further changes beyond these three rounds will be billed as additional hours of work. For a full breakdown of our legal obligations and the scope of work, please refer to our Terms and Conditions.

Our pricing is transparent and based on the complexity of the stem group. For stem mastering, we charge per track. The price listed includes the Australian Goods and Services Tax (GST) at 10%. For B2B clients, the price excluding GST is provided for accounting purposes. Payment is structured with a 50% deposit required to start the project, with the remainder due upon approval of the final master.
