Free Stuff We Use

For the lawyers, we should point out that the things here do have licenses, and so aren't entirely free. We just mean the licenses are relatively unrestrictive, and you don't need to give away your hard-earned cash.

In our products, we use:

Software

  • The Rapture3D Ambisonic Player uses libsndfile which is written by Erik de Castro Lopo and licensed under the LGPL. It's a really useful C library for reading and writing soundfiles. It's available from http://www.mega-nerd.com/libsndfile/.
  • Most of the Blue Ripple Sound graphical user interface components in our stand-alone applications have been written using wxWidgets. This is a cross-platform C++ GUI toolkit which is written by Julian Smart and others and is licensed under a variant of the LGPL. It is available from http://wxwidgets.org.
  • The OSX version of Rapture3D use the PortAudio Portable Real-Time Audio Library, which is Copyright 1999-2008 Ross Bencina, Phil Burk and others. See http://www.portaudio.com.
  • Our VST plugins use libpng, by Guy Eric Schalnat, Andreas Dilger, John Bowler, Glenn Randers-Pehrson, and others. See http://www.libpng.org.

Data

We use the following HRTF data. Note that we process the data quite heavily, so don't blame the folk below if things don't work for you!

UHJ Stereo to Ambisonic B-Format Conversion

We provide a simple Windows UHJ stereo to Ambisonic B-Format conversion tool for Windows. It converts stereo material that is in the UHJ format (typically from Nimbus Records) into Ambisonic B-Format (using just the WXY channels). It uses the "naive" speaker-agnostic approach to this.
