Soundhack, the free audio tool for the Mac developed by audio wizard Tom Erbe, was long a beloved tool for doing strange and wonderful things for sound. It was followed by Spectral Shapers, Mac and Windows plug-ins that built on some of those ideas to do more “timbral morphing” with recorded audio. That includes “timbral filtering” and noise-reducing expansion with spectralcompand, drawn morphing filter shapes with morphfilter, audio positioning with binaural, and a terrific spectralgate for creative dynamics processing.

In what can only come as great news to lovers of patching in the free and open source Pure Data (Pd) and commercial Max/MSP environments alike, those tools are now in beta as objects to include in your own patches. These patching environments really do feel like the virtual modular studios they are. Included:

+binaural, +morphfilter, +spectralcompand, +spectralgate, +decimate, +chebyshev, +matrix, +compand, +delay, +pitchdelay and +bubbler

This release promises a few bugs, so use at your own risk and write good, precise bug reports if you hit any trouble. Windows Max support isn’t there yet, but Mac Max support is, and Pd users can enjoy the software on Mac, Windows, Linux, and even 64-bit Linux. More updates coming later this summer.

  • If ever there was a reason for me to try my hand at Pd again, this just might be it.

    go tom erbe!!!!!!!!!!!!!!!!!!

    Thanks for sharing this! Now I can make me some digital drugs with the binaural object. Peter you really should write about this new fad. I couldn't believe this when I first heard about. Kids are now getting 'high' from binaural beats.

  • Wow, this is great news — thanks to all the developers involved!

  • @Bynar: Okay, we obviously need to get something going to "lure kids" to "getting high off digital signal processing."

    Pd — your first hit is free. Actually, so are all your other hits.

    Side effects may occur:
    * Upsetting your cat
    * Loss of sleep as you stay up patching
    * Repetitive stress injuries from connecting patch cords (actually, Exile did that to himself with Reaktor)
    * Increased consumption of caffeine
    * Gateway drug, leading to learning C, programming
    * Loss of interest in other activities
    * Strange looks from your friends

    Awesome Tom! +bubbler is great.
