# To decode an audio source with Rodio, you need to enable the appropriate features for *both* the
# demuxer and the decoder.
#
# Audio files consist of a demuxer (container format) and a decoder (audio codec), for example:
# - .mp3 is an MPEG-1 Audio Layer III file, which is a container format that uses the MP3 codec
# - .mp4 is an MPEG-4 container, typically (but not always) with an AAC-encoded audio stream
# - .ogg is an Ogg container with a Vorbis-encoded audio stream
#
# A reasonable set of audio demuxers and decoders for most applications.
