Free Windows Guitar Synth


Spicy Guitar is a free real-time acoustic guitar synthesis app for windows.

The Spicy Guitar project is the product of one year’s work by two students at the Ecole Centrale Paris:

“We wanted to combine our passion for music, specifically the guitar, with our experience in the sciences.”

Thanks to an original idea, we have developed a real-time sound synthesis software simulating acoustic guitar tones. It is based on physical modeling algorithms inspired by research works on modal synthesis, physical modeling, and convolution technology.

Since the mechanical and acoustic properties of the instrument are incorporated in our models, Spicy Guitar realistically simulates different guitars.

It is far from perfect, as we mainly focused our efforts on the synthesis method itself. Thus, you may find the playability to be basic, and you may experience some difficulties in using Spicy Guitar in your own compositions. But it is a good indication of the potential future of virtual acoustic instruments: more science and less use of samples!

One thought on “Free Windows Guitar Synth

  1. This is actually nice and useful. It does not offer much variation in terms of guitar models, but what it does, it does well and you can always process the sound with Guitar Rig, Amplitube, or other fx and get various tones.
    My wishlist: Make it respond to MIDI Pitch Bend data and add a few more chord types (major and minor 7ths at least).
    Even better, make it "recognize" chords on a keyboard and translate it to guitar chord voicings with adjustable strum speed.
    Thank you! You created something really useful!
