Voice agents · Enterprise
PolyAI reduced false barge-ins by 40% and short-utterance failures by 30% across 2,000+ enterprise deployments in 75 languages.
Voice agents · Enterprise
telli scaled to 5 million calls with enterprise-grade reliability, cutting the audio failures that cost 5–8x to escalate to a human.
Voice cloning · AI avatars
Synthesia achived cleaner voice clones, stable speaker identity, and a simpler modeling pipeline - just by fixing audio at the source.
Creator tools · VST3
Elgato now provides tudio-quality sound for millions of creators, running entirely on CPU, no audio engineering required.

"The adoption process was effortless. It was engineer to engineer on Slack. No bureaucracy. Just real conversations and fast progress."
Stephan Nöthen
Principal Product Architect, Elgato
"Voice cloning is highly sensitive to acoustic inconsistencies. Using ai-coustics to clean audio upstream simplifies modeling and keeps speaker identity stable."
Adam Froghyaria
Senior Research Engineer, Synthesia
"The integration was super quick and easy. Across our Voice Agents, we see major performance improvements in turn-taking as well as audio understanding. Highly recommended for any voice-first product."
Jeremy Meidinger
Founder / CTO, HiDesk
"ai-coustics effectively mitigates reverb, clipping, and compression artifacts, making high standards easy."
Chris Guse
CEO, BosePark Productions GmbH
"Integrating ai-coustics makes it easier than ever for Sieve developers to enhance video and audio files with state-of-the-art-quality."
