Is it possible to capture the playing audio with Java?

Question

I was wondering if it's possible to capture playing audio on the audio output hardware with a simple Java program, and then write it to an outputstream for example.

Is it?

Different question (at least as asked): yesterday's asks about recording what is output by the current app, this asks about recording what is going to the hardware, possibly by other apps. – Cotopaxi

Answer 1

If your desire is to record the output of all programs to a given audio device using a java app, like audiohijackpro, the short answer is no, this is not possible without native code. It is, in fact, quite difficult to do in any language. As far as I know, no platform makes this easy.

On some environments, there is a workaround, eg, http://cycling74.com/soundflower-landing-page/, but it requires that your end user cooperate.

I'm looking for a native solution but one with a command line interface. Do you know one ? – Depravity

@Depravity depends on your platform and audio API. The short answer is probably not. – Cotopaxi

but there are large number of softwares that are able to record speaker output, anyways, I'll keep looking. – Depravity
