Gnaural

Yes, the Gnaural tracker is closed because, as said in closing, the stuff you posted was all PortAudio language/code/errors.

In other words, "Unanticipated host error" and all that other stuff referred (as you can see) to things starting with "Pa" - that's PortAudio, none of it was my lingo or my code, and i have no idea how to fix PortAudio code. The main value of your report to me was as another vote to find an alternative to PortAudio, which seems to be faltering in it's development as an easy way to do audio on three platforms (Mac, Linux, Windows).

Big picture: PortAudio is a library you installed on your computer, and probably just as a normal part of installing Ubuntu: http://www.portaudio.com/ Gnaural uses this library, along with several dozen other libraries to run on your computer.

As to why Gnaural not Gnaural2 - my guess is that you downloaded the static-linked version of Gnaural: gnaural_1.0.20090808-i486.zip

That is a static-linked executable, provided as a no-installation-necessary convenience for users on distributions not having an official Gnaural installation package. For obvious reasons, static linked executables just can't work on EVERY system, because the static-linked app can't know or be prepared what supporting libs are going to be on every system. And in the case where they don't, as apparently is the case on yours, you simply have to follow the official approach to installing software. In your case, this would be either: 1) Install Gnaural from an already prepared Ubuntu "deb" or 2) compile it yourself

If there is no Ubuntu Gnaural for you to install, you can download and try the Debian installer i made at your own risk: gnaural1.0.20090808-1i386.deb

But gurus will always say never install a Debian deb on Ubuntu or an Ubuntu deb on Debian or else you will destroy civilization, etc. And yet i do it all the time; and yes, occasionally i get in some trouble - Macromedia Flash took two days to clean-up.

So given that, i'd suggest you just compile Gnaural yourself - then you are sure to have a version exactly tailored to your set of libraries. Always the way to go, but most people don't find compiling programs very convenient.
