Additive audio synthesis engine produces colorful animated patterns and electronic synth sounds.

WaveSynth Editor Sketch

The PixelAudio demo application WaveSynthEditor makes hypnotic animated patterns that can be saved to video or played as an additive synthesis audio source. It provides an introduction to the WaveSynth class and the WaveData objects that WaveSynths use to generate visual patterns and audio signals.

This application lets you edit a PixelAudio WaveSynth, including its individual WaveData operators, using a nice GUI made with g4p_controls for Processing. This sketch shows some of what you can do with the HilbertGen for making patterns with the WaveSynth. There are lots of other possibilities. Patterns can be loaded from and saved to JSON files.

For audio signals, a WaveSynth behaves like an audio synthesizer that adds together sine waves at different frequencies. The BigWaveSynthAudio and WaveSynthSequencer example sketches also produce audio with a WaveSynth. This example provides a graphical user interface for editing the colors and other properties of a WaveSynth.

Click on the WaveSynth image or press spacebar to hear the audio version of the image. Note that the appearance of the image is determined by the current sampling frequency, set in the initWaveSynth() method. For a higher sampling rate, there are more samples. One sampling rate I commonly use for the WaveSynth Editor is the number of pixels in the WaveSynth image, 1024 * 1024 = 1048576. Though it may have more or less samples, the sound of the audio will not vary, as its frequency is governed by the sampling rate. If you want to save the audio to a file, you should probably set a standard sampling rate like 48000 in the initWaveSynth() method.

A WaveSynth is organized around attributes, such as gain (i.e. loudness or brightness) and gamma (a sort of contrast setting), and data objects. The data objects include a a bitmap, mapImage, that is a Processing PImage instance for the image representation of the WaveSynth, a PixelAudioMapper that allows the WaveSynth to mediate between audio data and image data using arrays for the audio signal and the image data ordered along the PixelAudioMapper signal path, and an array of WaveData objects that define the individual sine wave components of the WaveSynth.

NOTE: Changes to data fields in the Control Panel will not be applied immediately to the WaveSynth image and audio. Click the Refresh button to force an update. Stepping to the next or previous operator will also refresh audio and image. If the display window is active, stepping to another frame 'y', 'u', or 'e' key commands) will also force an update.

When a WaveSynth is used to produce color patterns, each WaveData object in the waveDataList controls a color. The colors of the various WaveData objects are added together. The amplitude of the controlling sine wave controls the brightness of each color. The control panel in this example allows you to isolate individual WaveData operators to see how they affect the color patterns.

SAMPLING RATES FOR AUDIO AND FOR WAVESYNTH IMAGES

We use different sampling rates for audio playback and recording and for WaveSynth's additive synthesis algorithm. We use the standard sampling rate 48000 Hz for audio output. A 48000 Hz sampling rate fits conveniently with Hilbert curve dimensions. For the WaveSynth, which in this demo app relies on Hilbert curves to make patterns, we use (genWidth * genWidth) as the sampling rate for the sine waves that are added together to produce the WaveSynth image. If genWidth = 512, this value is 262144. You can change the audio sampling rate in the instance variables list or in setup(). You can change WaveSynth's sampling rate in the initWaveSynth() method.

In addition to the GUI commands, there are some useful key commands.

--------------------------------------------------------------------------------------------- ***>> NOTE: Key commands only work when the image display window is the front window. <<*** ---------------------------------------------------------------------------------------------

Key commands will NOT work when the control panel is the active window. Click on the display window to make it the active window and then try the commands. See the parseKey() method and the methods it calls for more information about key commands.

The quickest way to record a video, from frame 0 to the stop frame value in the control panel, is to press the 'V' (capital 'v') key.

The code in this example is extensively annotated. We the author heartily recommend you read the notes for the various methods.

Method Details
- main
  
  public static void main(String[] args)
  
  Used in Eclipse IDE and other Java environments to launch application. Delete in Processing.
  
  Parameters:
  
  args -
- settings
  
  public void settings()
  
  The settings() method is required when setting size from variables
  
  Overrides:
  
  settings in class processing.core.PApplet
- setup
  
  public void setup()
  
  Prepare for launch by setting all variables required for the draw() loop. Initialize the PixelAudio library, then create a PixelMapGen and a PixelAudioMapper Next set up a WaveSynth and point our global mapImage to the WaveSynth's variable mapImage. Check for extra displays, decide where to show the application window, and set the window scaling variables. Finally, build the GUI (using G4P library).
  
  Overrides:
  
  setup in class processing.core.PApplet
- stop
  
  public void stop()
  
  turn off audio processing when we exit
  
  Overrides:
  
  stop in class processing.core.PApplet
- createHilbertGen
  
  public HilbertGen createHilbertGen(int edgeLength)
  
  Parameters:
  
  edgeLength - length in pixels of Hilbert curve, must be a power of 2.
  
  Returns:
  
  a HilbertGen with its mapping arrays initialized
- hilbertLoop3x2
  
  public MultiGen hilbertLoop3x2(int genW, int genH)
  
  Generates a looping fractal signal path consisting of 6 HilbertGens, arranged 3 wide and 2 tall, to fit a 3 * genW by 2 * genH image. This particular MultiGen configuration is used so extensively in my sample code that I've given it a factory method in the HilbertGen class. It's written out here so you can see how it works. Note that genH must equal genW and both must be powers of 2. For the image size we're using in this example, genW = image width / 3 and genH = image height / 2.
  
  Parameters:
  
  genW - width of each HilbertGen
  
  genH - height of each HilbertGen
  
  Returns:
  
  a 3 x 2 array of Hilbert curves, connected in a loop (3 * genWidth by 2 * genHeight pixels)
- initWaveDataList
  
  public ArrayList<WaveData> initWaveDataList()
  
  Returns:
  
  an ArrayList of WaveData objects used to initialize a WaveSynth
- initWaveSynth
  
  public WaveSynth initWaveSynth(WaveSynth synth)
  
  Sets the initial values of a WaveSynth instance. Note particularly how varying sampleRate can change the appearance of the WaveSynth mapImage. SampleRate should not change the sound of the audio signal -- only the image changes. Some sampling rates are not standard for saving to file, so you may want to use a standard rate such as 48000Hz if you want to save audio to a file.
  
  Parameters:
  
  synth - a WaveSynth instance
  
  Returns:
  
  the WaveSynth with initial values set
- draw
  
  public void draw()
  
  Overrides:
  
  draw in class processing.core.PApplet

- setScaling
  
  public void setScaling()
  
  Calculates window sizes for displaying mapImage at actual size and at full screen. Press the 'r' key to resize the display window. This method will result in display on a second screen, if one is available. If mapImage is smaller than the screen, mapImage is displayed at size on startup and resizing zooms the image. If mapImage is bigger than the display, mapImage is fit to the screen on startup and resizing shows it at full size, partially filling the window.

  Bottleneck "commit" method for audio state. Takes an arbitrary input signal and installs it as the canonical audio signal used by the application. This method: - Resizes/pads/truncates the input to mapper.getSize() - Copies the data to ensure no external aliasing - Updates audioSignal (canonical signal handled by application code) - Updates audioBuffer (audio buffer used by Minim audio library methods) - Propagates the buffer to active instruments: edit for your own instruments This is the ONLY method that should mutate the global audio signal state. In PixelAudio examples, the signal is typically loaded from a file, but it could also be signal cached in memory, a signal generated by code, audio captured live, etc.
  
  Parameters:
  
  sig - an audio signal
  
  bufferSampleRate - audio sample rate for sig, usually obtained when reading from an audio file
- updateAudioChain
  
  void updateAudioChain(float[] sig)
- saveToAudio
  
  public void saveToAudio()
  
  Save audio buffer to a file called "wavesynth_(wsIndex).wav".
- renderSignal
  
  public void renderSignal()
  
  Calls WaveSynth to render a audio sample array derived from the same math that creates the image, then loads the derived audio data to audioBuffer, ready to be played.
- playSample
  
  public int playSample(int samplePos, int samplelen, float amplitude, ADSRParams env)
  
  Plays an audio sample with WFSamplerInstrument and custom ADSR.
  
  Parameters:
  
  samplePos - position of the sample in the audio buffer
  
  samplelen - length of the sample (will be adjusted)
  
  amplitude - amplitude of the sample on playback
  
  env - an ADSR envelope for the sample
  
  Returns:
  
  the calculated sample length in samples
- playSample
  
  public int playSample(int samplePos, int samplelen, float amplitude)
  
  Plays an audio sample with WFSamplerInstrument and default ADSR.
  
  Parameters:
  
  samplePos - position of the sample in the audio buffer
  
  samplelen - length of the sample (will be adjusted)
