Source Audio is an American effects pedal manufacturer based in Woburn, Massachusetts, near Boston. The company was founded in 2005 by Roger Smith and Jesse Remignanti, both former engineers at semiconductor firm Analog Devices, alongside chief scientist Bob Chidlaw, who brought digital signal processing expertise from Kurzweil Music Systems. Source Audio launched its first product in 2006 — the Hot Hand, a motion-sensing ring controller that allowed players to manipulate effects parameters through hand gestures, establishing the company's reputation for technology-forward design.

The product line spans delay, reverb, modulation, distortion, synth, equalization, and compression pedals for guitar and bass. Flagship models include the Ventris Dual Reverb, Nemesis Delay, Collider Delay+Reverb, C4 Synth, Aftershock Bass Distortion, EQ2 Programmable Equalizer, and the True Spring Reverb. Many of their pedals integrate with the Neuro software platform, enabling deep parameter editing and preset management via desktop or mobile apps. Source Audio's DSP-driven approach packs multiple algorithms and extensive tweakability into compact pedal formats.

Source Audio pedals have been used by artists across a wide range of genres, including Victor Wooten, Johnny Marr, Billy Strings, and members of bands such as King Crimson, Phish, The Cure, and My Morning Jacket. The company has earned awards from publications including Premier Guitar, Guitar Player, Guitar World, Sound On Sound, and Bass Player.
