Additional Datasets
Music, speech, and voice data – customizable to spec for any use case.
Speech Recognition & Voice AI
Enhance speech recognition, processing, and voice identification systems to improve accuracy in applications like virtual assistants, transcription services, and voice authentication.
Environmental Sound Recognition
Train AI to interpret real-world sounds such as alarms, footsteps, or weather – to power smarter machine perception for accessibility tools, assistive tech, transportation, and connected devices.
Active Noise Cancellation & Audio Separation
Optimize sound clarity through active noise cancellation and audio source separation, ideal for communication tools, broadcast enhancement, and audio restoration.
Generative Audio & Text-to-Sound Models
Fuel creative AI applications with data for GenAI tools that generate sound effects, compose music from text prompts, or develop entirely new audio experiences.
Audio Classification & Workflow Tools
Support non-generative AI systems focused on audio analysis, categorization, and enhancement – perfect for content moderation, audio tagging, and intelligent sound classification.
Dynamic Sound Retrieval & RAG Systems
Enable retrieval-augmented generation (RAG) by training models to intelligently surface relevant pre-existing sounds in real time – ideal for adaptive GenAI, search, and dynamic playback.
“The breadth of audio scenes gives us great coverage for training our speech recognition algorithms, enabling us to better future-proof products.”
Technical Lead, Cisco
Trusted Partner Since 2004
With deep expertise in all things audio, we support AI innovation with a dedicated product team and in-house data specialists – collaborating with MIT-affiliated researchers to ensure practical, efficient solutions.
Curated Quality
We’ve spent tens of thousands of hours capturing, tagging, and building our library to industry standards and beyond. Every sound is created by leading recordists, and every file is human-tagged and curated by our in-house library team.
Full Rights, Flexible Licensing
We own the rights to our entire library – unlike aggregators or crowdsourced datasets – giving you clarity and flexibility. We work with partners to structure legal terms for any use case, from GenAI to internal R&D.
Custom Dataset Support
Whether you need a targeted subset, specific categories, or additional modalities like speech or music, we can deliver exactly what you need – quickly, within budget, and at scale.
Ethical by Design
As a company founded and run by artists and creators, we're committed to building AI tools that support creativity and honor the craft behind every sound.
Built to Accelerate Your Roadmap
From licensing clarity to metadata quality, our goal is simple: reduce integration time, streamline onboarding, and get you to market faster.
Designed to Empower
Human Creativity
Our purpose is to help creators bring ideas to life through sound, and our multi-year product roadmap centers around partnering with companies that share this value. We are committed to ethically monetizing our library wherever creators are working with sound, whether directly or through partnerships. In turn, we will continue to support our artist earnings and new opportunities.
