Bugs we know of.

• RadioStation doesn't check the bit-rate of the files it streams and will cheerfully stream files of different bit-rates, which will confuse players that don't support variable-bit-rate streams (and that's most of them.) The results won't sound pretty. In the future the server will at least skip files with mismatched bit-rates.
• Variable-bit-rate MP3 files will not be served properly -- the server will probably try to push the bits too quickly or too slowly, since it uses the bitrate of the first MPEG frame to determine the data rate at which to send out the entire file.
• Non-ascii characters (like accented letters) in the configuration files will probably, depending on your OS, be mangled. This may cause problems if the file path to your MP3 files contains such characters. This is due to a deficiency in Java's property-file parsing code (it always uses the character set ISO-8859-1). If this affects you, the only workaround I can suggest is to rename your directories...

Compatibility issues.

• Audion (a shareware Mac MP3 player) sometimes has trouble keeping its buffer full and briefly glitches the audio. This seems to happen most often in the first few seconds of a stream, and occasionally at the very start of an audio track. This is mostly due to limitations of the buffering code in Audion 1.5; the upcoming version 2.0 should have an improved buffer.
