Altered Isolate vs Sencial API

Altered Isolate has no write-up on Specifiction yet; its figures are above.

Sencial API is an audio-processing API that provides REST endpoints for separating, detecting, isolating, and analyzing sound. Its /v1/separate endpoint creates 2, 4, or 6 audio stems with lossless export. Scene detection classifies acoustic environments in real time, while isolation endpoints can focus on or suppress selected sources and enhance voices against background noise. The diarization endpoint separates and labels multiple speakers, and voice embeddings return 512-dimensional vectors for matching and clustering. WebSocket endpoints support low-latency streaming, and the Jobs API handles asynchronous work through polling or webhook notifications. Developers receive API documentation, a quick-start guide, and Python, JavaScript, and cURL examples. The free Starter plan includes 10 minutes of monthly processing, all endpoints, and 128 kbps MP3 output without a credit card. Developer costs $49 per month, with 300 minutes, real-time processing, WAV/FLAC output, and $0.20-per-minute overages. Enterprise pricing is custom.
