How to Clean a Separated Vocal Stem (Demucs, htdemucs, Spleeter)

A stem pulled out of a mix carries two different problems — residue smeared through the signal you kept, and bleed from the instruments around it. How to tell which one you have, and why the order you treat them in matters.

Snare Ring: How to Kill the Ring and Keep the Crack

Gates cut the tail and the body with it; EQ notches dull the stick. The ring is harmonic and the stick is percussive — separate them and you can attenuate one without touching the other.

How to Remove Room Resonance From Vocals (Without Notching the Life Out of Them)

A room resonance only blooms on certain notes, but a static notch cuts that frequency for the whole take. Why a dynamic EQ band gets closer, and what per-bin suppression does differently.

Suno Artifacts: Why Tracks Sound Metallic (and How to Remove Them)

What the metallic shimmer and watery sustains in Suno tracks actually are, why the free plan's MP3 export makes them worse, and which preset to reach for depending on your export format.

The Genre Wall

Closing the genre gap and the false-positive rate we promised to fix — a ground-up retrain on 27,476 tracks, a borderline-call review model, and the deployment bug we caught mid-rollout.

Beyond SOTA

Negative results, evaluation leakage, and what we measured wrong — three failed experiments, a data-leakage discovery, and the real weakness hiding behind an illusory one.

Toward Real-Time

Distillation and runtime — why light doesn't mean fast. Two parameter-count inversions, a causal real-time UNet, and a 50x speedup from a single ONNX surgery.

How to Detect AI-Generated Music — Methods and Tools

Listening cues, spectrogram analysis, and automated forensic tools for identifying AI-generated music from Suno, Udio, Stable Audio, and more. Includes benchmark comparison.

How to Fix AI Music Artifacts (Suno, Udio, Stable Audio)

Step-by-step guide to removing the metallic, watery, swirly artifacts from AI-generated music. Covers RVQ ghosting, codec residue, and HF aliasing — what they are and how to fix them.

The Benchmark Saturation Trap

Chasing SONICS scores while real-world performance collapses — how a benchmark-saturated model went from SOTA to a 4.3% detection rate on the newest generator, and the fair-comparison harness we built in response.
