ShuiCast is a plugin for both Winamp and Foobar2000 that provides the ability to broadcast various audio formats to a few of the major broadcasting servers. It is a continuation of the Oddcast/Edcast streaming software that can stream to either Icecast or Shoutcast servers, integrating changes made by the AltaCast and Edcast-Reborn spinoffs.
Features:
- Stream to IceCast or ShoutCast
- Support for Ogg Vorbis, LAME (lame_enc.dll), and AAC (libfaac.dll) – note lame_enc.dll and libfaac.dll must be downloaded separately in order to use these formats
- Multiple encoders (you can simultaneously broadcast in multiple formats at the same time)
- Standalone application as well as plugin for Winamp, RadioDJ and Foobar2000
- Metadata not only from media player (i.e. Winamp) but also from a file, a URL or a window
- Peak and RMS Meter
- Live Recording (you can switch on/off without disconnecting the encoder)
Dynamic Audio Normalizer is a library for advanced audio normalization purposes. It applies a certain amount of gain to the input audio in order to bring its peak magnitude to a target level (e.g. 0 dBFS). However, in contrast to more “simple” normalization algorithms, the Dynamic Audio Normalizer dynamically re-adjusts the gain factor to the input audio. This allows for applying extra gain to the “quiet” sections of the audio while avoiding distortions or clipping the “loud” sections. In other words: The Dynamic Audio Normalizer will “even out” the volume of quiet and loud sections, in the sense that the volume of each section is brought to the same target level. Note, however, that the Dynamic Audio Normalizer achieves this goal without applying “dynamic range compression”. It will retain 100% of the dynamic range within each “local” region of the audio file.
The Dynamic Audio Normalizer is available as a small standalone command-line utility and also as an effect in the SoX audio processor as well as in the FFmpeg audio/video converter. Furthermore, it can be integrated into your favourite DAW (digital audio workstation), as a VST plug-in, or into your favourite media player, as a Winamp plug-in. Last but not least, the “core” library can be integrated into custom applications easily, thanks to a straightforward API (application programming interface). The “native” API is written in C++, but language bindings for C99 Microsoft.NET, Java, Python and Pascal are provided.

MilkDrop is a music visualizer – a “plug-in” or extension to Winamp or Foobar2000 music players. As you listen your music in Winamp, MilkDrop takes you flying through the actual sound waves you’re hearing, and uses beat detection to trigger myriad psychedelic effects, creating a rich visual journey through sound. MilkDrop can also be driven by a live audio feed (microphone or line-in).
