As the licensor of software libraries, we provide users with a voice compression-related software library collection SDK (Software Development Kit). Users do not need to develop specific vocoder functions; they can simply select our SDK package to easily implement voice compression functionality on their own platforms.

(1) SDK Composition

A typical SDK contains three parts:

• Lib —— Header files and library files (i.e., API, encapsulating the vocoder algorithm, providing calling interfaces and macro definition parameters)

• Doc —— Help documentation (i.e., user manual, introducing relevant information, interface definitions, example code, and recording version information)

• Demo —— Calling examples (i.e., demonstration projects, projects or compiled code that call the vocoder software library based on the user's platform)

(2) Platforms Supported by the SDK

This voice processing SDK adopts a modular layered architecture and cross-platform design principles, achieving good architectural decoupling and portability, and can run stably on various processor architectures and operating system environments. The core algorithms have been adapted, performance-optimized, and system-level verified on the supported platforms mentioned above.

Through targeted optimizations for different instruction set characteristics, memory structures, and real-time scheduling mechanisms, the system can achieve predictable real-time processing capabilities, low end-to-end processing latency, and stable resource usage control across various hardware environments.
