minimalist audio encoder for generating live streams

 GlassCoder is a minimalist audio encoder for IceCase and Soutcase
 streaming servers as well as HTTP Live Streaming (HLS). It supports
 the following audio sources:
 .
 Advanced Linux Sound Architecture (ALSA)
 File Streaming (FILE)
 JACK Audio Connection Kit (JACK)
 .
 The base GlassCoder streamer component utilizes no configuration files or
 GUI interface whatsoever; with the 'user interface' consisting entirely of
 the command-line invocation. As such, it is well suited for use cases where
 the encoder is completely driven by an external system or script.
 .
 The following audio codecs are supported:
 .
 MPEG-1/1.5 Layer 3 ('MP3')
 Ogg Opus
 Ogg Vorbis
 PCM16
 .
 Also included is GlassGui, a graphical point-and-click interface that can
 be used to drive GlassCoder or generate command-line invocations that
 can be copy/pasted to other systems
