Developer Cargo Cult has unveiled an interesting sound design tool called Envy. It’s designed for thorough envelope modulation, enabling interesting possibilities like transplanting the volume and pitch characteristics of a sound onto a completely different one.
Examples cited by the developer include morphing gunshots into wind noises, imparting a drum pattern onto a vacuum cleaner recording, and other highly experimental ditties with an unexpected outcome.
Not unlike a vocoder, Envy is able to act over four frequency bands, applying a separate envelope onto each one. The resulting sound may end up “speaking” like the source. For example, you can make crowd chants this way — apply the envelope of your vocal onto a crowd noise recording and hear the result.
Envy also supports pitch bending with vibrato, so you can pitch recordings up and down at up to 6 octaves. This is accomplished by way of drawing pitch bends onto audio clips. There are dedicated pitch shifting algorithms for dialog, transient, and rhythmic sounds as well as Bad and Worse pitch modes for serious audio mangling. Yikes! Check out the manufacturer’s video below for a demonstration.
Price and availability
Overall, Envy is an interesting tool but its compatibility is limited to Pro Tools 11 or later on macOS. This means no VST or AU support for the time being, though Windows compatibility is said to be coming.

Money-wise, Envy currently costs USD 259 on an introductory price, with regular pricing set at USD 359. An iLok v2 or v3 dongle is required for authorization.
