About this project

The audio.opus R package provides a wrapper around opus-tools (xiph/opus-tools) for handling Opus audio format operations. It enables encoding, inspecting, and decoding Opus audio files, with primary functionality focused on converting opus files to WAV format to facilitate automatic transcription using audio.whisper. The README states this conversion is faster than using ffmpeg via the av package. Installation requires system dependencies: libopus and libogg, with specific instructions provided for Windows (RTools), Mac (Homebrew), and Ubuntu (apt). The package is installed from GitHub as it is not available on CRAN. Key functions include opus_decode demonstrated in conversion examples. Maintained by BNOSAC for text mining support.
