Anyone know if it is possible to write an app that uses the Java Sound API on a system that doesn’t actually have a hardware sound device?

I have some code I’ve written based on the API that manipulates some audio and plays the result but I am now trying to run this in a server environment, where the audio will be recorded to a file instead of played to line out.

The server I’m running on has no sound card, and I seem to be running into roadblocks with Java Sound not being able to allocate any lines if there is not a Mixer that supports it. (And with no hardware devices I’m getting no Mixers.)

Any info would be much appreciated –

thanks.

  1. For linux you can use OSS Virtual Mixer, which will give you virtual sound channels.

    On windows there are a few sound drivers that do this, one is Virtual Audio Cable, which, while not free, is about the cost of a sound card so it shouldn’t be a hardship.

    If neither of those work for you, it’ll probably be easier to make your own Java sound library and replace the built in functionality than it would be to implement a sound card for your OS.
