Over the past six months, we have worked closely with teams using both the ai-coustics SDK and the ai-coustics API. During this time, customer demand has become clearly concentrated around real-time speech enhancement for Voice AI systems. To fully focus on this segment, we will discontinue the ai-coustics API on March 31, 2026. Our long-term focus is on real-time Voice AI pipelines and on-device SDK deployments, including VAD, Voice Focus, and ASR-optimized preprocessing. Maintaining a general-purpose API limits our ability to invest fully in these areas.

Unused credits

Any remaining prepaid balances will be refunded or, if preferred, converted into SDK credit. We will reach out individually with your remaining balance details.

Continuing with ai-coustics

Our real-time SDK remains fully supported for teams building Voice AI applications, offering low-latency processing, on-device or on-premise deployment, built-in VAD, and Voice Focus. We appreciate every team that has built with the ai-coustics API. This step allows us to focus fully on reliable Voice AI infrastructure.

SDK vs. API

The ai-coustics API processed audio files. That means you uploaded a recording and received an enhanced version back. The SDK works differently: it processes audio in real time, frame by frame, as a stream. It is designed to sit inside a live audio pipeline (e.g. a voice call or a Voice AI agent), not to batch-process files. If you were using the API to test or evaluate enhancement quality on recordings, the playgrounds are the closest equivalent:
