Our AI mastering engine analyzes your mix and applies a mastering chain to deliver a streaming-ready master. It’s built, designed and tunned for rock, metal, punk, grunge, metalcore, deathcore, indie — and more.
Drop in WAV, MP3, AAC, or FLAC. For best results, use a clean export with headroom (no clipping).
The AI measures loudness, dynamics, tonal balance, and stereo image to decide what your track needs.
A/B your original vs AI master right in the browser and hear the difference before you commit.
Export your master and share it. HD exports (like 24-bit WAV) can be unlocked on upgrade.
Tip: If you want the best AI mastering result, export a clean mix (no limiter on the master bus) and leave headroom.
We’ve prepared a before-and-after master for you to test. To mark the launch of the new platform, we’re making it free for now.
The AI-Mastered version demonstrates an effective enhancement in loudness through dynamic range compression, a more balanced frequency response with emphasized lows and refined mids, and controlled highs to reduce harshness. These changes collectively improve the track's clarity, punch, and listening consistency, addressing dynamic and spectral irregularities apparent in the original unprocessed version.
The AI Mastered version addresses the original's uneven dynamics and frequency imbalances effectively. It enhances low-end presence, clarifies mid-range content, and controls high frequencies to reduce harshness. Dynamic range compression is applied judiciously, preserving punch and transient details while increasing perceived loudness. These changes suggest a technically sound mastering approach that results in a more commercially competitive and sonically pleasing track.
(Reference levels vary; masters can be louder — platforms will turn down loud tracks.)
Human Mosh mastering is built and tuned with advanced AI for how guitar-driven music actually translates — from intimate indie mixes to full-tilt metal. You get punch for drums, weight for low-end, clarity for vocals and guitars, and controlled loudness for streaming. Pick your lane — the engine adapts the chain to match the sound you’re chasing.
This isn’t “one preset for every song.” The system evaluates your track’s transients, density, spectral balance, and stereo width so the master fits the music — whether it’s a tight, modern metal mix, a roomy live take, a noisy punk recording, or a clean indie record with lots of space. Different scenes need different translation, and the chain adjusts for that.
Pro tip: For the cleanest master, upload a mix with a bit of headroom and no hard clipping on the master bus. Bedroom mixes, rehearsal takes, and studio mixes all work — the goal is a clean signal to build from. If you want to explain it in more depth, link a guide here later (optional).
Controls harshness, tightens low-end, and keeps kick + bass readable under dense guitars, fast cymbals, and stacked layers — without turning everything into a flat brick.
Keeps vocals forward, adds bite without fizzy harshness, and locks the master so it stays punchy on small speakers, car systems, and earbuds.
Preserves vibe and texture while improving translation: clear mids, controlled mud, and width that feels immersive without drifting out of focus.
Adds impact without crushing dynamics: tight low-mids, controlled edge, and a master that stays loud without turning fatiguing over a full listen.
Manages space and width: keeps ambience wide and deep while maintaining center focus, steady low-end, and detail that survives streaming playback.
This section is designed to match high-intent searches like “AI mastering for metal,” “AI mastering for punk,” “AI mastering for grunge,” and “AI mastering for indie rock,” while staying readable for every scene.
Human Mosh delivers professional AI mastering online for guitar-driven artists and bands — from clean indie records and grunge textures to hardcore speed and metal density. The focus is simple: power, clarity, and reliable translation across real-world playback systems — without generic, one-size-fits-all results.
Masters are optimized for modern streaming platforms using controlled loudness targets and musical dynamic preservation. Your track stays punchy and clear across indie, rock, punk, and metal without harsh clipping, weird pumping, or listener fatigue.
The engine reads what your mix is doing — dense guitars, layered distortion, breakdown-heavy arrangements, live-room drums, or atmospheric walls. Each master adapts to the music’s priorities instead of forcing generic EQ curves.
Loudness is achieved without crushing transients or flattening energy. Impact, punch, and movement are retained so your music still hits on speakers, headphones, cars, and stage playback.
Download professional-grade masters in high-resolution WAV for distribution, archiving, and pressing — with MP3 exports also available for previews, private sharing, and quick checks.
Advanced true-peak management helps prevent hidden clipping and inter-sample distortion, so your master translates cleanly on consumer systems, club rigs, rehearsal PAs, and streaming platforms — even when the mix is dense.
Upload new mixes, compare revisions, and A/B results as often as you need — whether it’s a DIY demo, a live take, or a polished studio mix. You only commit when the master feels right.
Human Mosh AI Mastering is an advanced AI mastering engine built for heavy and alternative music. It’s the final stage after mixing — the step that makes a track translate everywhere while keeping the energy that matters in metal, punk, grunge, indie rock, and metalcore.
The engine analyzes your mix — dynamics, tonal balance, stereo field, and loudness — then applies a genre-aware mastering chain: corrective EQ, multi-band dynamics, harmonic saturation, and true peak limiting. You get a release-ready master delivered in high-resolution 24-bit WAV and 320kbps MP3, optimized for modern streaming and real-world playback.
Most online mastering tools lean “one-size-fits-all.” That can fall apart on heavy music because dense guitars, aggressive cymbals, and fast transients can trigger harshness, pumping, or flattened dynamics.
Human Mosh is tuned for Indie Rock, Alternative, Punk, Grunge, Metal, Hardcore, and Metalcore. That means it prioritizes tight low-end without boom, controls cymbal edge without dulling the mix, and preserves the impact of kicks/snares and breakdown hits while still achieving competitive streaming loudness.
This is one of the hardest problems in rock and metal mastering: distorted guitars and bass fight for space while cymbals can get spiky fast. Human Mosh uses intelligent multi-band dynamics plus dynamic EQ to keep the low end defined and the top end controlled.
The result: bass stays solid without swallowing the kick, guitars keep weight without harsh “ice-pick” fizz, and cymbals stay present without taking your head off — so the master hits hard and still translates on earbuds, cars, and loud rehearsal systems.
Human Mosh is tuned to keep vocals forward without turning them brittle. It identifies key vocal presence ranges and applies subtle EQ and control to reduce harshness and sibilance while preserving the texture.
For punk, grunge, post-hardcore, and metalcore, that means screams feel intense and clear, cleans feel stable and “glued,” and the vocal sits in the wall of guitars instead of disappearing or getting painfully sharp.
For the strongest masters, send the cleanest mix possible. Use this checklist:
Yes. Streaming platforms use LUFS loudness normalization. If your master is too loud, it gets turned down — often making it feel smaller and less punchy. If it’s too quiet, it won’t compete.
Human Mosh targets a streaming-friendly loudness range (often around -14 LUFS integrated, depending on your mix) and applies true peak limiting to avoid intersample clipping. You get a loud, controlled master that keeps impact without distortion or “pumping.”
A top mastering engineer can absolutely add a creative edge—especially on major releases where the budget allows deep revisions and artistic direction.
Human Mosh AI is built for the real world: fast turnaround, consistent results, and masters that translate across streaming, cars, headphones, and live playback—without paying studio rates every time.
It’s ideal for DIY bands, frequent drops, singles, demos that need to sound release-ready, and heavy/alternative mixes where you want punch, clarity, and width without crushing the dynamics.
