Here's a crude example (I don't have all those libraries so couldn't add it to your code): float scroll = 0 You can set up a variable for the translation so that you can control this with your mouse. Push the matrix, translate the z coordinate once before drawing everything you want zoomed out, pop the matrix. Push and popping the matrix will manipulate the matrix stack - you create a new 'frame' where you can play around with translations, then pop back the original frame (so you don't get lost by applying new translations on each frame). You can use pushMatrix and popMatrix in combination with translate. However, there might be an easier solution here. You can use matrices to create a camera object, there is tons of material out there that you can read up on to understand the math behind this and implement it anywhere. Guess my understanding of it is lacking too. Y = height/2- in.right.get(i) * height/2 Įdit: you don't need push and pop matrix here. draw the waveforms so we can see what we are monitoringįor(int i = 0 i < in.bufferSize() - 1 i++) use the getLineIn method of the Minim object to get an AudioInputįrames++ //same saying frames = frames+1 My sketch is adapted from a minim example Sketch.Īll Help is greatly appreciated. I've tried changing the buffer size, and changing the multiplier for x/y. I'm not sure what I'm doing wrong here or what's wrong with my code.

I don't really know how to explain it, but I want to 'zoom out' from where I am getting the peaks in waveforms, which is the window size. I'm trying to make my own virtual oscillograph in processing. IIS-0713334.I'm a total beginner so forgive me if this is probably silly or improper of me to ask. This material is based in part upon work supported by the National Shift-drag the mouse closer to the bottom of the screen to damp more. plucked_string_damp adds an interactive damping feature: shift-click while the string is sounding to simulate 'touching' the string at a particular point to sound the harmonics. You can choose the pluck point and initial displacement interactively with the mouse. plucked_string simulates a plucked string by calculating two traveling waves moving in opposite directions.KSPiano is another typing-piano, but this time the note waveforms are generated in the sketch itself using the Karplus-Strong plucked string algorithm.Here, each pitch is rendered with a sine oscillator whose envelope decays smoothly. SinePiano implements a crude piano using the bottom two rows of keys on the computer keyboard.The modified version LiveSpectrogram_window allows you to vary the length of the time window, for interactive LiveSpectrogram plots the live spectrum and several seconds of its history as a scrolling grayscale image (a spectrogram).(A slight modification to the minim forward FFT example). LiveSpectrum takes the FFT of the input audio and plots it, in dB, on the screen.Attempts to 'trigger' to keep a stable waveform. Keyboard controls '+', '-' adjust height of trace, '' adjust time base. Oscilloscope just plots a short excerpt of the input waveform.You can check it out live as the PlaySpectrum_filt_applet.

(This code was written to illustrate how to implement arbitrary filters in minim).

PlaySpectrum_filt does much the same thing, but is based on the improved version of LiveSpectrum with axis labels, and implements its own BPF rather than using minim's built-in one. Note: you have to put a soundfile named 'sound.mp3' in the sketch's directory for it to find and play.

Playback_BPF loops an MP3 file, applies a bandpass filter under interactive mouse control, and plots the spectrum of what's being played (showing the effect of the filter).

It also plots the resulting spectrum in real-time.

AudioSocket_BPF builds upon the AudioSocket loop by adding a bandpass filter that you can control in real time with the mouse (based on the minim example bandpassfilter).

AudioSocketExample defines a class (including a FIFO audio buffer) to connect line in to line out, for a live audio processing loop within Processing.

Using minim that are on the main Processing site. They are based on the minim sound library included in This page is a place where I can put some of the little ``sketches'' I have developed It as part of the Music Signal ProcessingĬlass as a quick way to build audio processing examples that you can interact with in real On Java, and has found a strong following for art-style applications.

Processing is a very neat programming environmentĭeveloped to allow users to quickly try out and develop small pieces of code. Examples of Audio Processing in 'Processing'
