Overview

Note:

This module is private and its methods are meant to be used internally by decoders.

Utility module providing shell-based audio decoding support for decoder classes.

This module is intended to be mixed into decoder classes that rely on external tools such as ffmpeg, mpg123, or sox to decode audio files. It builds the appropriate shell commands, executes them, and converts the raw audio data into

Numo::NArray

samples.

Examples:

Using within a decoder

class Mp3Decoder < B
  include Awaaz::Utils::ViaShell

  def load
    process(*shell_load(sox_options: { raw: true }))
  end
end
