Fast preview, streaming-aware loudness, and clean true-peak headroom so your master survives encoding.
We've taken two BTR tracks and mastered them to show you the before and after.
The AI Mastered track that is louder and dynamically controlled, with enhanced low-frequency energy, balanced midrange, and clear but smooth high frequencies. It successfully addresses the broader dynamic fluctuations and spectral unevenness apparent in the original by delivering a tighter, punchier, and more polished sound suitable for professional release.
The AI Mastered version addresses typical issues seen in the Original track by: Controlling dynamic range through compression and limiting to achieve louder, more consistent playback levels with preserved punch. Enhancing low-end frequencies to impart fullness and weight. Clarifying the midrange for better instrument and vocal presence. Taming harsh highs to reduce listener fatigue and increase perceived fidelity. Overall, the AI mastering improves loudness, balance, and clarity while maintaining enough dynamic elements to keep the track lively and engaging.
(Reference levels vary; masters can be louder — platforms will turn down loud tracks.)

Valkyrie is an advanced AI mastering engine designed for 2026. It acts as your personal audio engineer, performing the final critical step of music production. Our AI analyzes the sonic characteristics of your uploaded mix—its dynamics, frequency balance, stereo width, and loudness—and applies a custom chain of processing.
This includes precise equalization, multi-band compression, harmonic saturation, and true peak limiting. The result is a professional, polished master that is perfectly optimized in high-resolution 24-bit WAV and 320kbps MP3 formats, ready for release on all major streaming platforms.
Upgrading from the free preview unlocks our complete professional workflow, designed to manage your music after mastering. Key benefits include:
Many online music mastering services use a generic, "one-size-fits-all" model. Valkyrie is different. Our engine was built from the ground up and trained on a massive dataset of successful tracks in Rap, Hip-Hop, Trap, Reggae, R&B, and Afrobeats. This genre-specific intelligence means it understands the nuances that matter to you.
Instead of just making a track louder, Valkyrie knows how to handle the deep sub-bass of an 808, the snap of a trap snare, and the presence of a rap vocal without sacrificing clarity. For urban music producers looking for a master that respects the genre's conventions, our specialized approach delivers a more powerful and authentic result.
This is one of the biggest challenges in modern production and where Valkyrie excels. A common issue is the kick drum and 808 bass competing for the same low-frequency space, resulting in a muddy, undefined master. Our AI uses intelligent multi-band dynamics and dynamic EQ to solve this.
It can subtly carve out space for the kick's transient to punch through while keeping the 808's body full and powerful. It ensures your low-end has both clarity and weight, translating perfectly even on smaller speakers, a common problem with DIY mastering.
Absolutely. The Valkyrie engine's adaptive processing is tuned to enhance the warmth, presence, and clarity of vocal performances. It identifies the key vocal frequencies and applies subtle equalization to help them sit perfectly in the mix without sounding harsh or sibilant. For R&B, soul, and melodic rap songs, this means achieving that professional "radio-ready" vocal sound that feels both intimate and powerful.
To get the absolute best results from any mastering process, preparation is key. Follow these simple steps:
Yes. This is a primary function of our AI. In 2026, all major streaming platforms use LUFS loudness normalization to create a consistent listening experience. If you upload a track that's too loud, they turn it down, often resulting in a loss of punch. If it's too quiet, it won't feel competitive.
Valkyrie targets the industry-standard "sweet spot" (typically around -14 LUFS integrated) and uses advanced true peak limiting to avoid intersample peaks. This ensures your music is loud, clear, and impactful on every platform without ever being penalized or distorted.
This is the most important question. A seasoned human engineer with years of experience on a specific project will always have a unique creative touch. However, Valkyrie AI offers a powerful and professional alternative that excels in consistency, speed, and affordability, often surpassing the quality of budget-level or inexperienced engineers.
Our AI Music Mastering was trained on thousands of hit records, allowing it to make musically intelligent decisions instantly. It's the perfect solution for producers on a budget, artists needing a fast turnaround for demos or singles, and anyone who wants a high-quality, release-ready master without the high cost and long wait times of a traditional studio.
