The Spectrum Intelligent Filter is the most powerful stereo filter effect pedal ever created. Building on almost 15 years of filter pedal technology and know-how, Spectrum is the culmination of Source Audio's finest envelope sounds and best thinking on how to easily incorporate those sounds into rigs of all types. The pedal not only features finely crafted envelope filter effects inspired by some of the most iconic and sought-after effects pedals on the market, it also includes buzzing, synth-like octave/distortion/filter effects. The pedal is a cleverly integrated, all-in-one funk/psych/electronic/jam machine.

Whether you want to easily plug and play with its six carefully crafted factory sounds, browse the ever-growing Neuro library for additional sounds created by Source Audio and other Spectrum owners, or use the Neuro's deep sound editing tools to create your own highly personalized presets, this filter pedal will satisfy the needs of any guitar, bass, keyboard, horn, or (insert your instrument here) player.

Plug In and Play
The Spectrum Intelligent Filter was designed with special attention given to the simple plug-and-play experience. Right out of the box the Spectrum offers easy access to tones inspired by some of the most iconic and difficult to find envelope filters effects pedals on the market. It also offers synth-like tones comprised of distorted octave and envelope phaser sounds. Because of the pedal's ALT button, the Spectrum's four knob control surface actually offers access to eight different parameters. Use the Spectrum's Input Gain, Sensitivity and Speed controls to dial in the perfect envelope response for your needs. Maybe you like a slow and smooth envelope movement while you really dig-in on the strings, or possibly you want a quick moving filter that responds to light picking - either way is achievable with the Spectrum.​ The Frequency, Resonance, Depth and Mix controls provide fine control over the color and character of your filter effects. Whatever your needs, the Spectrum is the most comprehensive filter effects pedal available.

The Neuro Editing Systems
On the surface, the Spectrum Intelligent Filter features a simple 4-knob interface and a choice of six amazing guitar/bass envelope filter effects - just plug-in and play. If you want to take things to take things a bit further, Source Audio urges that you connect the Spectrum to our Neuro Preset Editing and Browsing tools. The Neuro Mobile App is available for free at the App Store (iOS) and Google Play (Android). The Neuro Desktop Editor is available as a free download for Mac or Windows systems. Inside Neuro you will find the tools to create your own one-of-a-kind envelope tone. Use the Spectrum's collection of two parallel filter voices, octave up or down effects, and distortion to dial in that perfect tone. The Neuro also offers a growing collection of additional envelope filter presets created by the Source Audio team as well as the ever-expanding community of Spectrum users - just touch the screen to open a preset in your Spectrum. If you like what you hear, hit the BURN button and upload the preset to any of the pedal's six toggle switch positions.
