Bitviewer is a little plugin that allows you to
check the bit depth of the incoming audio
stream, so you can see how much headroom
you still have for processing and if you really
need dithering.

DC Killer is a plugin that gets rid of the infamous
DC offsets in your audio stream! 4 different
algorithms are provided, all work quite well in
eliminating the unwanted offset.

ChannelGrabber is a nifty little VST plugin that
allows you to grab the incoming audio stream
and save it as a WAV file. It does also include a
gain control (with optional automatic adjustments)
and a peak meter and full MIDI control.

Overloader is a plugin that makes a sound if
the input goes above a certain level. Good for
checking for high peaks on a certain track.
You can even turn this into a generator for
various beeps.

Kondor is a very powerful tool/plugin, and
unique of its kind in the VST world: it does not
make any sounds, but rather analyzes and
displays all data received from the host. An
indispensable tool for all VST plugin and host
developers! You can even let Kondor "imitate"
certain configurations on the plugin side to test
how the host reacts!

MixBox is a powerful plugin that allows you to
share and mix audio streams between different
plugin instances or even applications!

With 4 internal busses that are shared across
each instance of the plugin, you can easily
realize a submixer (with up to 5-channels) or
stream the audio from one application/VST host
to another.

P-Bugger is a simple plugin to show how drastic
the Pentium 4 denormal bug can affect
performance and how easy it is to fix. If you don't
have a P4, then you can still use this plugin as a
flexible bandpass filter :-)
