Freeware – 9 VST Bundle

EasyQ
Key Features
unlimited number of filter stages (“bands”)
each stage can be one of the following characteristics: bell, low-/high-shelf, low-/highpass (6 or 12 dB/oct), notch
clean equalization – no additional colorations
low CPU usage
+-48 dB gain range
stereo modes: linked, left/right, mid/side and mono
minimum phase response
EasyQ is an easy-to-use equalizer with an arbitrary number of filter stages in series connection. Each of the filter stages can operate in one of the following modes: peak/cut (aka bell or parametric EQ), high- or low-shelving, notch and low- or highpass (both with either 6 or 12 dB/oct slope). EasyQ is also easy on the CPU and just does what an EQ is supposed to do without performing any additional voodoo. As such, it is well suited to serve as a go-to EQ for the routine equalizing tasks.

CrossOver
Key Features
Splits signal in up to 4 frequency bands
separation between bands up to 96 dB/oct
flat sum due to Linkwitz/Riley filters
CrossOver is a plugin to split an incoming signal into several (at most 4) frequency ranges. It can be used to build your own multiband effects within a modular (sub)host environment. By using only 2 bands, you can also create bass-effects. These are effects which keep the low frequency range dry and affect only the high frequency range. The band-splitting is done by complementary pairs of Linkwitz-Riley lowpass/highpass filters, the slope of which is adjustable between 12 and 96 dB/oct. For configurations with more than 2 output bands, the signal is first split into 2 bands (low and high) and then the low or high or both bands is/are split further, thus the splitting is done in a hierarchical manner.

EngineersFilter
Key Features
ultra-steep filters possible
design methods: Bessel, Butterworth, Chebychev I and II, elliptic, Papoulis
characteristics: lowpass, highpass, bandpass, bandreject, low-/high shelf, peak
EngineersFilter is a filter plugin that allows for extremely steep filtering. It achieves this by implementing high order IIR filter design methods that are commonly used in science and engineering, namely Butterworth, Chebychev, inverse Chebychev, elliptic (aka Cauer), Bessel and Papoulis filters. Each of these filter design methods can be applied to create lowpass, highpass, bandpass, bandreject, high/low shelving and peak/dip filters of orders up to 20.

FuncShaper
Key Features
arbitrary transfer functions via math-expressions
input- and output-filters
up to 16x oversampling
FuncShaper is a waveshaping distortion plugin based on a mathematical expression evaluator. You can enter an expression to create the function which will be used as waveshaping transfer function. The expression may contain arithmetic operators, well known standard functions (sin, cos, tanh, etc.) as well as some proprietary special functions, which are specifically geared towards the application domain (soft-clipping, Chebychev polynomials, etc.).

TrackMeter
Key Features
level meters for left, right, mid and side signals
adjustable ballistics with predefined values for VU and PPM
correlation meter
Track Meter is a plugin to display the current level of a stereo input signal separately for the left, right, mid and side channels and also to display the cross-correlation between the two channels. You may freely adjust the rise- and fall time constants (collectively called ballistics). Convenient buttons exist for using the standardized ballistics for VU and PPM measurements.

Signal Analyzer
Key Features
oscilloscope and spectrum analyzer
independent zoom for both axes
synchronization to input signal (oscilloscope)
spectral resolution up to 32768 bands
Signal Analyzer is a combined oscilloscope/spectrum-analyzer plugin for inspecting signals in realtime in the time- and frequency domain. The oscilloscope’s refresh rate may be synchronized to the period of the incoming signal to stabilize the plot of periodic waveforms. Both views may be frozen and the frozen display can be exported into a .png file.

ChannelMatrix2x2
Key Features
arbitrary redistribution of 2-channel (stereo) signals
boost, M/S encode/decode, swap channels, invert polarity, etc.
Channel Matrix 2×2 is a plugin which lets you matrix-multiply the signals of two input channels in order to obtain another two signals which will appear at the two output channels. Example uses are mid/side encoding/decoding, mixing stereo to mono, switching channels left for right, boosting or attenuating signals, inverting signal polarity, etc.

PitchShifter
Key Features
granular-based pitch shifting algorithm
adaption of grain-length to input signal period
feedback
Pitch Shifter is a plugIn to shift the pitch of an incoming audio signal. By mixing the pitch-shifted signal with the original signal via the dry/wet control, basic detuning, octaving and harmonizing effects are also possible. This shifter is based on a delayline with two crossfaded read pointers. Such an architecture allows for feedback – and feedback gives the potential to rather drastic, weird special effects like monster-voices, flanger-like effects and more.

MidiMonitor
Key Features
shows note-events, controllers, pitch-wheel and much more
event filter (to show only events that are of interest)
2 versions available (for VST-effect and VST-instrument slots)
MIDI Monitor is a plugin which shows you the incoming MIDI messages. Because some hosts treat instrument- and effect-plugins differently (and do not allow plugging one kind of plugin into a slot of a different kind), there is an ‘instrument’ and an ‘effect’ version of the plugin to make it pluggable everywhere. The MIDI-events are passed through unchanged, the same holds for any incoming audio signal.
