public class TutorialOne_06_WB_Retrofit
extends TutorialOne_03_Drawing

Eclipse-only example of how to retrofit WaveBuffer feature to Drawing tutorial. A continuation of TutorialOne_03_Drawing that keeps the drawing, brush, sampler, granular, bounds, and envelope code from TutorialOne_03_Drawing, but changes the audio source model: - anthemSignal / anthemBuffer hold the entire loaded audio file. - windowBuff is a moving window over anthemSignal. - audioSignal / playBuffer / mapImage hold only the current visible window. - Display coordinates map first to the visible window, then to the backing full-file source by adding windowBuff.getIndex(). This file is intentionally small: it is a retrofit layer over the newer TutorialOne_03_Drawing rather than a refactor of the older TutorialOne_06 code. It is not ported to Processing. The programming model in Eclipse provides better support for the Java classes than Processing does. See TutorialOne_03_Drawing

Overrides:

setup in class TutorialOne_03_Drawing

initAudio

public void initAudio()

Initializes audio using the TutorialOne_03_Drawing defaults, then creates an initial full-file backing source from the empty playBuffer.

Overrides:

initAudio in class TutorialOne_03_Drawing

loadAudioFile

public void loadAudioFile(File audFile)

Loads an audio file through TutorialOne_03_Drawing's normal path. The override of updateAudioChain(...) below receives the full resampled signal and installs it as the backing source instead of truncating it before instrument playback.

Overrides:

loadAudioFile in class TutorialOne_03_Drawing

Parameters:

audFile - an audio file

suspendWindowAudio

void suspendWindowAudio()

updateAudioChain

void updateAudioChain(float[] sig,

Parameters:

sig - an audio signal

sourceSampleRate - audio sample rate for sig, usually obtained when reading from an audio file

updateAudioChain

 float sourceSampleRate)

Installs a full-file backing source for WindowedBuffer and instruments. Sets the window size to mapper.getSize()

refreshWindowFromBacking

Returns:

a PVector with the x and y coordinates

handleClickOutsideBrush

public int handleClickOutsideBrush(int x,

float[] backingGranularSignal()

playGranularGesture

public void playGranularGesture(float[] buf,
 GestureSchedule sched,
 GestureGranularParams params,

Parameters:

buf - an audio signal as an array of float

sched - an GestureSchedule with coordinate and timing information

params - a bundle of control parameters for granular synthesis

pan - position of sound in the stereo audio field (-1.0 = left, 0.0 = center, 1.0 = right)

Returns:

draw

public void draw()

Advance the visible audio window during draw().

Overrides:

draw in class TutorialOne_03_Drawing

parseKey

public void parseKey(char key,
 int keyCode)

Add WindowBuffer controls, then pass all other commands to TutorialOne_03_Drawing. T toggle automatic window traversal { } jump backward / forward one whole window [ ] jump backward / forward one half window R rewind the audio window Y toggle random point events while windowing
