Products and Modules
On-device SDKs and cloud APIs for real-time music interaction, score-aware analysis, and music AI pipelines.
On-device SDKs
Low-latency · Mobile & web · Real-time interactionDemo available
Piano Transcription SDK
Low-latency on-device piano note detection for real-time feedback, practice apps, digital instruments, and web or mobile products.
Real-time score following
Track a live performer inside the score and keep accompaniment, cursor, feedback, and interaction synchronized in musical time - regardless of tempo variations.
Adaptive accompaniment
Tempo-aware accompaniment playback that follows the musician's live tempo instead of forcing fixed-speed practice. The core engine behind Metronaut.
Demo coming soon
Musical echo suppression
Music-specific echo suppression that keeps microphone input usable while accompaniment or backing tracks play through speakers.
Real-time latency compensation
Live delay estimation and compensation for Bluetooth, speakers, and device audio paths - keeping audio, UI, and interactions synchronized.
Score-synchronized recordings
Attach audio or video recordings to notation so review, sharing, and teacher feedback can navigate by score position.
Cloud APIs
Score-aware · Structured output · Compute-intensive analysisDemo available
Performance assessment API
High-precision audio-to-score alignment with assessment of timing, pitch, tempo shifts, retakes, errors, and deviations. Returns structured JSON.
Semantic alignment API
Transform audio and scores into structured semantic data for timing, segmentation, transcription training, and performance understanding.
Antescofo Platform provides real-time score following SDKs, piano transcription technology, performance assessment APIs, and score-audio alignment tools for music education apps, interactive sheet music, catalog processing, and AI training pipelines.
Production proof
The same technology powers Metronaut.
Not a demo project - a live consumer product with real-time score following, performance assessment, echo suppression, and latency compensation deployed across iOS, Android, macOS, and web.
