# hooks: -
#
# 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.

# Filter streams by bitrate
class filter_bitrate():

    meta = plugin_meta()
    module = "filter_bitrate"

        if b <= 10:
            return True
        elif b < int(conf.min_bitrate_mp3):
            return False

#    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.)
