As you rock the pedal, the frequency changes, the whole EQ curve shifts, and you get this impression of a voice-like tone. Whether an automatic or a controlled version, wah pedals have a sweepable peak frequency that’s filtered out. The most famous example of a filter pedal is a wah-wah. It is done “dynamically” since the EQ curve How Do Envelope Filter Pedals Work?Įnvelope filter pedals do their magic by filtering specificįrequencies in your tone and letting through specific desired part of AUDIO FILTER SIGNAL PATH FREEThere are no strict rules for genres where you can implement envelope filters, and you’re always free to experiment. You can often hear them in funk music, or any music that features funky elements in it. To put it simply, it often resembles the tone of those old school synths. This way, some frequencies that passed through the filter are way more pronounced than others near them.įor guitars and bass guitars, you get that voice-like or vowel-like tone with each played note. What’s also special about envelop filters is that they use resonance in order to emphasize desired frequencies. The curve changes, starting from the moment that you play the note and until it fades out, or until you play the next note. The word “envelope” refers to different EQ curve “shapes” of the guitar or bass tone. But the envelope filters, or just filters, are the names given to specific types of pedals. Higher frequencies, and the so-called “band-pass” that letsĮQ pedals are technically filters, with multiple frequency range controls on it. We also have high-pass filtering that passes only the Signal’s audible spectrum go through, while the others are filteredĪlso heard about low-pass filters, that allow only the bottom-end of Suggests) filters out certain frequencies. Filters feature a circuit that (as their name Things up, we first need to sort out what “filtering” inĪudio processing means. An envelope filter also reacts to the dynamics and attack of your playing enhancing the intensity when plucking hard or decreasing it when playing softer. Within the vast world of guitar effects, you may have come across an envelope filter pedal?īut what is an envelope filter? And what does this pedal do to our sound when added to our pedalboard?
