Mac OS X 10.6+, Intel chips only.

SoundMagic Spectral is a FREEWARE suite of 24 Audio Unit plug-ins that implement real-time spectral processing of sound. This groundbreaking set of effects give you unprecedented control and creativity in the processing of audio, whether from static audio files or live audio streams. SoundMagic Spectral builds on the work of the OS 9 software known as SoundMagic DSP, and takes it to even more exotic sonic realms.





Included in SOUNDMAGIC SPECTRAL are the following plug-ins:

Spectral Averaging • Spectral Bin Shift • Spectral Blurring • Spectral DroneMaker • Spectral Emergence • Spectral Filterbank • Spectral Freezing • Spectral Gate and Hold • Spectral Gliding Filters • Spectral Granulation • Spectral Harmonizer • Spectral Partial Glide • Spectral Pitch Shift • Spectral Pulsing • Spectral Shimmer • Spectral Shuffle • Spectral Stretch • Spectral Tracing • Spectral Weave • Chorus • Comb Filter Bank • Grain Streamer • Idee Fixer • Mr Filterbank

Beta 6: updated all effects to 64-bit/32-bit • fixed potential crashes in Spectral Filterbank & Granulation • added Spectral Weave effect • added "Gate Type" parameters to Spectral Gate & Hold • added a silence stage to Spectral Gate & Hold • fixed a crash in Spectral Bin Shift • added some new options to Spectral Bin Shift • fixed some incorrect operation in Spectral Freezing

Beta 5: fixed a crash in Spectral Stretching • fixed a crash in Spectral Pulsing • added some nice pulsing effects and delay vs. freq parameter to Spectral Gate & Hold • added some new options to Spectral Tracing for retaining/removing at different ends of the loudness spectrum • added a new "variance quantization" parameter to Spectral Stretching, allowing for interesting pitch variation effects • Idee Fixer now passes auval • made the default "Randomize Phases" settings more appropriate to each effect

Beta 4: Fixed some serious bugs with Spectral Dronemaker and Spectral Emergence. Added bin shift to Spectral Gate & Hold

Beta 3: Some new envelope possibilities in Spectral Gate & Hold, new plug-in "Idee Fixer"

Beta 2: Now validates correctly with auval, which means it can run in Logic; some code optimization across the board

Beta 1 UB: Now compiled as Universal Binaries

Beta 1: First beta release
