JackPort.getBuffer() vs JackPort.getFloatBuffer() about jnajack HOT 2 CLOSED

That mostly comes down to one question actually! 😄 JackPort caches the underlying ByteBuffer until the pointer changes. It also caches a FloatBuffer which is equivalent to calling ByteBuffer::asFloatBuffer. If you call JackPort.getBuffer().asFloatBuffer() you'll get exactly the same result, except that you'll create a lot of short-lasting FloatBuffer, and therefore unnecessary overhead / garbage.

The audio is normalised (-1 .. 1) 32-bit floating point data, which is the format that JACK uses.

The caching code is at - https://github.com/jaudiolibs/jnajack/blob/master/src/main/java/org/jaudiolibs/jnajack/JackClient.java#L777

Thank you, that helps a lot. I think this information could be mentioned in the asFloatBuffer() documentation.
