#
# 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.

#    slow, then slices out genres. No search. With the secret
#    "buffy" mode keeps all streams buffered.

#  → "Forbidden Fruits" extracts from dir.xiph.org HTML pages,
#    with homepages and listener/max infos available. Also
#    enables live server searching.
#
# The bitrate filter can strip any low-quality entries, but
# The previous bitrate filter is now a separate plugin, but
# retains `0` entries (which just lack meta information and
# aren't necessarily low-bitrate.)
