Class AudioRecorder

java.lang.Object

marytts.util.data.audio.AudioRecorder

public class AudioRecorder
extends Object

AudioRecorder: Recording to an audio file (advanced version)

Purpose

This program opens two lines: one for recording and one for playback. In an infinite loop, it reads data from the recording line and writes them to the playback line. You can use this to measure the delays inside Java Sound: Speak into the microphone and wait untill you hear yourself in the speakers. This can be used to experience the effect of changing the buffer sizes: use the '-e' and '-i' options. You will notice that the delays change, too.

Usage: java AudioRecorder -l java AudioRecorder [-M <mixername>] [-e <buffersize>] [-i <buffersize>] <audiofile>

Parameters:

• -l: lists the available mixers
• -M <mixername> selects a mixer to play on
• -e <buffersize> the buffer size to use in the application ("extern")
• -i <buffersize> the buffer size to use in Java Sound ("intern")

Bugs, limitations: There is no way to stop the program besides brute force (ctrl-C). There is no way to set the audio quality.

Source code: @see AudioRecorder.java, AudioCommon.java, gnu.getopt.Getopt
