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.
java AudioRecorder -l
java AudioRecorder [-M <mixername>] [-e <buffersize>] [-i <buffersize>] <audiofile>
Bugs, limitations. There is no way to stop the program besides brute force (ctrl-C). There is no way to set the audio quality.
