          edu.berkeley.guir.ptk.input.AudioInput

All Implemented Interfaces:

java.lang.Runnable

public class AudioInput

extends InputSource

Gets a volume and eight frequence samples from a microphone, creates an Event including them all, and dispatches it. The metadata of the events this class creates is AudioConstants.AUDIO. The data IDs are AudioConstants.VOLUME, and one of the AudioConstants.FREQUENCY[number] IDs.

Constructor Detail

AudioInput

public AudioInput()

Constructors for non-distributed applications. An input that uses this constructor cannot be part of an application on another machine.

Method Detail

newInput

public Events newInput()

Gets input from the data source, fills an EVent with it, and returns the Event.

Specified by:

newInput in class InputSource

setFreqsToZero

protected void setFreqsToZero()

copyFreqs

protected float[] copyFreqs(float[] f)

main

public static void main(java.lang.String[] argv)

Starts this Input with the IP address AudioConstants.DEFAULT_INPUT_IP and sets the time between events to AudioConstants.DEFAULT_AUDIO_TIME_BETWEEN_EVENTS. Can instead take one command line parameter: (1) IP address where this Input is running.

Parameters:

argv - IP address where this Input is running, as a String.
