MelSpectrum · 融谱智能科技 — 让机器听懂声音
一半是声学，一半是算法。我们把振动，变成理解。We turn vibrations into understanding.
Piano Tuner
把一位调律师的耳朵，装进口袋。实时 Railsback 曲线拟合，实验室测试调律精度 ±2 音分（最终性能以量产版本验证为准）。以断弦防护为第一优先级设计，固件支持双向 OTA 回滚。硬件研发中，iOS App 已在 TestFlight。产品站：pianotuner.top
Somnil
在监测到睡眠相关事件时，把你轻轻唤醒。用额头四通道脑电（Fp1 / Fp2 / F7 / F8）做实时睡眠分期与梦魇检测，模型在端侧以 CoreML 推理。公开临床基准被试级留出：Sleep-EDF 准确率 0.785 / κ 0.715，CAP 七类病理人群 0.761 / κ 0.683；非真机验证。产品站：somnil.top

English — MelSpectrum teaches machines to listen — half acoustics, half algorithms. Piano Tuner reaches a lab-tested ±2-cent tuning accuracy through real-time Railsback curve fitting, and is designed with string protection as its first priority; final performance is whatever the production version verifies. Somnil performs real-time sleep staging and nightmare detection from four channels of frontal EEG (Fp1 / Fp2 / F7 / F8), inferred on-device with CoreML — 0.785 accuracy and κ 0.715 on Sleep-EDF, 0.761 and κ 0.683 on CAP, both subject-wise held out on public clinical benchmarks and not validated on our own hardware. We operate AS218883 with primary address block 2a0e:4001:3000::/40, seen by 153 of 153 RIPE RIS full-table peers on 2026-10-22. The operator inventory as of 2026-10-22 records eight routing locations: Los Angeles (LAX), Salt Lake City (SLC), Hong Kong (HKG), London (LON), St. Louis (STL), Tokyo (TYO), Taipei (TPE) and Frankfurt (FRA). The production host is web1.lax.us.net.melspectrum.com (2a0e:4001:3010:400::80). Legacy 2a13:c8c3:e803::/48 was withdrawn on 2026-09-28 and AMS is retired; 2602:f92a:a463::/48 is retiring.
