_audio

The quickest way to encode FLAC files to lossy formats using a simple I/O ffmpeg task.
You can install ffmpeg with brew install ffmpeg or sudo apt-get install ffmpeg

Options

  • --mp3: Encodes the input as MP3 using lame.
  • --aac: Encodes the input as AAC using libvo_aacenc. Due to the experimental nature of AAC encoding in ffmpeg this isn't really stable (no cover art e.g) and only to use if you really want it.
  • 256: Second option that you can pass trough, encodes as 256kbps.
  • 320: Same as above but 320kbps

Defaults

Just running _audio in a shell will output a 256kbps MP3. My personal preference is _audio --aac or audio 320

Disclaimer: this could probably be cleaner. Vars are scoped locally within the function.
