About:
OpenCORE-AMR provides a high-performance implementation of the AMR (Adaptive Multi-Rate) speech codec and the AMR-WB (Wideband) variant. Extracted from the Android open-source project, it enables applications to encode and decode audio streams using these standard 3GPP formats. This library is essential for handling voice data in telecommunications and mobile media applications.
Key Features:
  • Implements both AMR-NB and AMR-WB speech codecs
  • Provides ANSI C source code for maximum portability
  • Includes encoder and decoder libraries for integration
  • Based on the reference implementation from 3GPP standards
Use Cases:
  • Decoding audio from 3GP mobile video files
  • Developing VoIP applications requiring AMR codec support
  • Transcoding audio streams for mobile compatibility
Alternatives:
  • opencore-amrnb – Legacy package name; opencore-amr is the modern standard.
  • vo-amrwbenc – Alternative implementation focused specifically on the AMR-WB encoder.
