Vocal-led pop, electronic, hip-hop, R&B, and singer-songwriter sit in the sweet spot. The reference bank covers those genres densely. Drum-and-bass and synthwave land too. For orchestral, brass-heavy big-band, or anything with extreme dynamic range, our mastering team takes the file by hand — write to mastering@sonichaos.io and we route it.
matchering 2.0 spectral-matches against a per-genre reference set. We tag every mix with CLAP and pick the top-three nearest references by cosine similarity, then average their frequency response. The match weight is exposed in the user log so you can see which references won.
Yes. The dialog at delivery offers the mastered WAV, the unmastered loudness-normalised reference, and a CSV with peak / LUFS-integrated / LUFS-short-term / true-peak readings against the target.
DeepFilterNet 3 handles hum, hiss, and HVAC noise. Hard clipping inside the source is detected and surfaced — the model won't try to invent transients that aren't there. You'll see a yellow note on the render and a one-line recommendation to back the source down by 1.5–3 dB.
Source files live in a private MinIO bucket on a Hetzner box in Helsinki. Encrypted at rest with AES-256. Deleted automatically 30 days after delivery, or the moment you click Delete in the dashboard. No third-party AI vendor sees the file.
