Does anyone have some Pseudocode for Karplus-Strong algorithm?
The Karplus-Strong algorithm is a digital signal processing technique used to synthesize a plucked string sound on a computer. It was developed in 1983 by Kevin Karplus and Alex Strong and has been widely used in music production and computer music research.
The algorithm takes an input signal, typically a noise signal, and applies a low-pass filter to it. The output of this filter is then fed back into the filter, creating a loop. The loop is repeatedly iterated, creating a decaying signal that resembles the sound of a plucked string.
Pseudocode is a high-level description of a computer program or algorithm written in plain English, without using any specific programming language syntax. It is used to outline the logic and structure of a program before writing actual code.
The Karplus-Strong algorithm can be written in pseudocode as follows:
1. Generate a buffer of random noise samples of length N.2. Set the loop index i to 0.3. While i < N: - Calculate the output sample by filtering the input sample with a low-pass filter. - Add the output sample to the end of the buffer. - Increment i by 1.4. Output the buffer of synthesized samples.
The main steps of the Karplus-Strong algorithm include generating a noise signal, applying a low-pass filter, feeding back the filtered signal into the filter, and repeating this process in a loop. The algorithm also involves adjusting the parameters of the filter and the length of the loop to achieve different sounds and pitches.
