And the bundle is available as a fully-functional, 14-day trial from the SoundHack website. They are somewhat CPU-intensive, but should not overburden most systems. Each of the plug-ins can be automated via MIDI controller messages, which is awesome for real-time control, live or in the studio. Tom Erbe's Spectral Shapers are well designed and thought-out, with classy, streamlined interfaces. Although it's optimized for headphone use, it's useful in creating a sense of depth and space in any mixing situation. +binaural simulates the filtering effect of the head and outer ears to place a sound at a specific position around the listener's head. Together with the tilt control, this morphing can result in subtle or radical sound designs and colorations. This can be done through MIDI (automatable of course) or via the built-in LFO (which can be sync'ed to the host DAW application).

The cool thing about this plug-in is its unique ability to morph between two saved filter curves. Here, the curve that you draw or capture becomes the frequency response of a filter. +morphfilter, like the other plug-ins, lets you draw a spectral image or capture the spectral shape of incoming audio. Then think of what it will do to your loops when you use extreme settings-it's awesome. Think of this plug-in as a frequency-dependent gate/ducker or level-dependent filter. This allows you to duck or gate specific frequencies without affecting others. +spectralgate, like +spectralcompand, divides incoming audio into 513 frequency bands and applies a noise gate to each. As with all the plug-ins in this suite, +spectralcompound can operate in pure mono, mono to stereo, stereo to stereo, or stereo linked modes. Separate controls for attack/release, make-up gain, and tilt (which alters the threshold shape by raising the high frequencies or lowering the lows, or vice-versa) all make for radical harmonic effects and highly adaptable noise- reduction possibilities. This feature is present in the +spectralgate plug as well and is a key aspect in the sound-mangling capability of these plug-ins. You can also draw a custom threshold shape in the main window, setting a separate threshold for each frequency.

Each band can be processed with a combination compressor/expander (hence "compand") with ratios ranging from 5:1 to 1:5. +spectralcompand is a dynamics plug-in which divides incoming audio into 513 frequency bands. All four use some form of spectral analysis to reshape timbre, but each does so in its own unique manner with amazing results. SoundHack Spectral Shapers are four VST/AU plug-ins (for OS 9, OS X, and Windows): +spectralcompand, +morphfilter, +binaural, and +spectralgate. Even more exciting is that he plans to release more SoundHack plug-ins in the near future. I absolutely love the original SoundHack sound design software, so I was excited to hear that Tom Erbe, designer of SoundHack, had released a new suite of plug- ins advancing some of the more esoteric timbre-shaping ideas in SoundHack.
