Feature request: add Fuzz plugin for Pedalboard (#402) #403
Conversation
…d. It features a two-stage clipping process: first a hard diode clipping (threshold=0.25), then a soft clipping via tanh, followed by a tone control stage implemented as a low-pass filter.
…t_fuzz_process_signal() methods added.

Excellent work, thank you @LorenzoMonti! I've left a couple comments inline (mostly about touching the actual DSP parameters directly in the setters/getters rather than copies) - but otherwise, this is virtually a perfect pull request. Great job!

We probably don't want to keep a copy of these variables here, as they can differ from the variables set in the ProcessorChain depending on when prepare is called. (And indeed; if you use Fuzz in an AudioStream, it should be possible to call .drive_db = x and the audio should update without needing to stop and start the stream again.)

Could try using ArrayCoefficients here to allow updating the toneHz parameter without requiring a realloc/extra prepare call here - with the caveat that I haven't worked with that API in a long time and am not sure if it would actually work here.
Thanks for the thorough and speedy comment! I’m still getting familiar with JUCE, so I really appreciate the guidance. I’ll go through your comments carefully and deepen my understanding of how the |
Problem
Fuzz is a staple effect in many music genres, particularly rock and
experimental electronic music. While distortion and gain effects exist
in Pedalboard, fuzz has a unique aggressive character that cannot be
easily replicated. Adding a fuzz plugin would expand Pedalboard’s
flexibility, providing more options for guitarists and producers
seeking vintage or experimental tones.
This feature request was initially discussed in #402.
Solution
Implemented a new Fuzz effect, emulating a classic fuzz pedal.
The effect consists of:
Result
Pedalboard now includes a fuzz effect, broadening its range of
distortion-based effects. Users can apply fuzz to their audio chains
for a distinctive saturated sound characteristic of classic fuzz pedals.
