About:
VoAmrwbenc is an open-source library that implements the VisualOn AMR-WB encoder specification. It provides a software-based solution for encoding audio into the AMR-WB (Wideband) format, commonly used in telecommunications and mobile applications. This library is part of the opencore-amr project and is essential for applications requiring AMR-WB encoding capabilities without proprietary dependencies.
Key Features:
  • Implements the VisualOn AMR-WB encoder specification
  • Provides a software-based solution for AMR-WB audio encoding
  • Part of the open-source opencore-amr project
  • Lightweight and efficient for integration into various applications
Use Cases:
  • Encoding audio for VoIP and telecommunications applications
  • Developing mobile applications that require AMR-WB audio support
  • Transcoding audio to the AMR-WB format for storage or streaming
Alternatives:
  • opencore-amr – Includes both encoder and decoder for AMR-WB and AMR-NB, while vo-amrwbenc focuses solely on the encoder
  • fdk-aac – Provides AAC encoding which is a different codec, often preferred for higher quality but not compatible with AMR-WB
