Decision brief

A package for faster speech-to-text transcription based on the Whisper model, using CTranslate2.

Avoid when

* When needing to employ FFmpeg directly for audio processing as it does not require FFmpeg installation and relies instead on PyAV.
* In environments where additional dependencies from PyAV may introduce complexity or issues.

Requirements:: Requires Python 3.9 or higher
