The ai-coustics SDK delivers real-time speech enhancement using our Quail model family running on the AirTen inference runtime.

Quail (real-time models)

Learn about Quail-S and Quail-L for ultra-low-latency enhancement.

AirTen runtime

Our Rust-based, no_std, ultra-fast runtime embedded in the SDK.

​
Models

Quail L

  • Processing latency: 30ms
  • Available sample rates:
    • 48 kHz
    • 16 kHz
    • 8 kHz

Quail S

  • Processing latency: 30ms
  • Available sample rates:
    • 48 kHz
    • 16 kHz
    • 8 kHz

Quail XS

  • Processing latency: 10ms
  • Available sample rates:
    • 48 kHz

Quail XXS

  • Processing latency: 10ms
  • Available sample rates:
    • 48 kHz
The SDK resamples the audio to the model’s sample rate as needed.

​
How the SDK is structured

  • Core library: C ABI delivered as static/dynamic libraries (Linux, macOS, Windows; x86_64, ARM64)
  • Language wrappers: C++, Python, and Rust packages for idiomatic usage
  • Real-time processing: 48/16/8 kHz streaming with frame-based processing and low latency

Quickstart

1

Get an SDK License

Self-service SDK Keys can be generated on the development portal.
Self-service SDK Keys are currently in Beta.These keys require a constant internet connection to function and are configured to collect telemetry.
To use the SDK in an offline environment, please contact us directly to obtain a special offline license that operates without these requirements.
