Clipping is the elimination of certain parts of the sound wave which makes it sound more distorted. This pedal circuit is designed to add fullness to the input signal with a simple phase chorus, amplify an..." current

Instead of relying on ones and zeros like in a digital computer, analog computers perform mathematical operations on continuous voltages instead. This makes them well suited to perform calculations invol..." current

They use cassette tape players to create the delay effect. In the most simple form, they take the output from the guitar and record it onto the cassette tape, then further along the tape the audio signal that was recorded onto the tape is read off and..." current

Using this circuit,  you can get a motor to drive something to the beat of music. The circuit takes an audio input and filters the signal with a low-pass filter to isolate the musical beats. The signal from the low-pass filte..." current

In traditional sequencers and also this sequencer, you turn a knob (potentiometer) to set the note for each step. So 4 knobs for a 4-step potentiometer. Modern sequencers are connected to a keyboard or a launchpad. A sequencer can record in step time o..." current
