# Plugin that filters radio stations on bitrate (audio quality).
# Anything below 64 kbit/s often sounds awful for MP3 streams.
# While AAC or Ogg Vorbis might still be acceptable sometimes.
#
# This functionality was previously just implemented for the Xiph
# plugin. It's now available as generic filter for all channels.
# Beware that some channels provide more entries with low bitrates,
# thus might appear completely empty.
