(1) AI audio analysis and stem separation
Analyze single or batch audio for rhythm/style, BPM, chords, vocals, and instruments. Separate vocals, drums, bass, piano, and accompaniment, and export results for QC, reconstruction, and asset breakdown.
MediCut Audio/Video Integration API
Open audio/video AI processing APIs for enterprises and developers
API Capability Overview
MediCut Audio/Video Integration API is built for enterprise developers, partner platforms, and product teams. It covers intelligent audio analysis, AI video editing, multi-track timeline work, media automation, and batch task orchestration, with async jobs, idempotency, quota billing, and permission control for short-video, post-production, creator, and commercial media pipelines.
Core Advantages
(2) Video extract, BGM replace, and multi-track editing
Vocal separation, vocal-removed composition, multi-segment mixing, fades, and gain. Timeline tools for layered tracks, clip edits, track mute, and custom render duration.
(3) General media automation
Unified tasks for enhancement, face/plate privacy masking, format conversion, denoise, clip/stitch, adding this platform’s watermark, subtitle burn-in, filters, picture-in-picture, A/V sync, speed, and covers. Single-file or batch.
(4) Enterprise Open API
API Key auth with idempotency, async callbacks, quotas, rate limits, billing reconciliation, error codes, and task-state queries for third-party, SaaS, and internal systems.
(5) Production task plumbing
Idempotent task submit, async status callbacks, unified responses and quota checks. Common media formats, larger files, and custom output resolution/bitrate/framerate.
(6) In-house resampling and one-pass export
Kaiser-sinc interpolation for band-limited reconstruction (stopband suppression on the order of -80 dB). One-read/one-write pipeline to cut repeated transcode loss; export target sample rates without third-party plugins.
Use Cases
Short-video creators: vocal-off backing tracks, vocal extract for subtitles, denoise for recuts, plus voice effects on longer clips.
Film/pro editors: seven-stem separation for vocals and instruments on long-form sources.
Live streaming/MCN: extract vocals from replays or strip background music for recuts.
Online education: boost instructor voice and reduce background noise on long recordings.
Enterprise office: extract speech from meetings, denoise and archive, with cloud collaboration.
Music creators/self-media: seven-stem split plus AI music and sound-effect workflows.
