The valid range of these numbers is debatable. You can experiment with different numbers to change the sound of the tone. This number controls the pitch of the beep. Obviously, the beep portion of the command is what generates the sound, but you will notice that there are two numbers following the beep.

So let's take a look at what this command is actually doing. The technique used for producing a basic tone is simple. That way, you can go do something else while the script is running, but know the instant that the script completes. For long-running scripts, it can be handy to get PowerShell to play a sound when the script completes. I have, on occasion, built scripts that took upwards of 20 minutes to execute. Some PowerShell scripts take a long time to run. As obnoxious as this probably seems, it does have its place. Recently, I have been experimenting with adding auditory prompts to PowerShell scripts. However, it is also possible to use PowerShell to produce audible output. Think about it for a moment: When you enter a cmdlet, PowerShell displays something on the screen in response, even if the output is only another PowerShell prompt, or even an error message. There's much more information on the Sun/Oracle website on Java headless mode.I have always thought of PowerShell as being primarily a visual interface.

:) Setting Java headless modeĪs one final note, if you'd rather specify the Java headless mode in your code instead of the command line, just add this line of code to your program: =true PlaySound sound1.wavĪnd I finally had what I wanted, a little program to play a sound file whose name I specify on the command line, with no undesired side-effects. To fix this problem I told the Java JVM to run in 'headless' mode, like this:

#PLAY SOUND COMMAND MAC#

This is when I noticed input focus was moving from my Mac Terminal window to 'somewhere else', and sure enough, I saw the Java icon in the Mac Doc. I fixed this error by running my Java command like this, telling the JVM it's okay to look in the current directory for my Java class file: It failed because my classpath wasn't set, as shown in this amazingly nasty-looking exception:Įxception in thread 'main' : PlaySoundĬaused by: : PlaySoundĪt $1.run(URLClassLoader.java:202)Īt (Native Method)Īt (URLClassLoader.java:190)Īt (ClassLoader.java:307)Īt $AppClassLoader.loadClass(Launcher.java:301)Īt (ClassLoader.java:248) When I went to run it like this it didn't work: play the audio clip with the audioplayer class create an audiostream from the inputstreamĪudioStream audioStream = new AudioStream(in) InputStream in = new FileInputStream(args)

('I need just one arg, the name of a sound file to play.')

* A simple Java sound file example (i.e., Java code to play a sound file). Here's the source code for my simple Java program that reads the name of a sound file as a command line argument, and then plays that sound file: Java sound application and Java headless mode

#PLAY SOUND COMMAND MAC OS X#

Upon writing my little Java sound application, I was quickly reminded that on Mac OS X running a Java program from the command line creates an icon in the Mac Dock, so I also added the 'headless' mode option to my command line arguments, as shown below. So, I wrote a quick little 'Java sound' program to read the name of a sound file from the command line, and then play the sound file. But, when you double-click a sound file on Mac OS X, it automatically plays through iTunes, which is good for some things, but bad for what I wanted to do. As part of my ongoing HAL 9000 voice obsession, I downloaded a bunch of 'HAL 9000' sound files last night.
