Atk FoaDecoderMatrix.newStereo not as expected

[joslloand]

Hello @aiode, if you’re having the same issue as ATK Binaural decoder, you’ll want to be sure to update the ATK quark.

You may want to review the installation documentation. All components should be kept up to date.

Actually I’d like to render to a binaural image (head phones). I managed to do it as following, where I had to instantiate the ~decoder first before using later, otherwise I encountered the same problem as reported here ATK Binaural decoder . Supposedly, that’s a timing issue.

The binaural decoder needs to be loaded before it is used. This is a kernel decoder, so is a collection of FIR filters that have to be read from disk. Here’s a brief discussion on the difference between matrix & kernel operations.

What does 1013 mean? I suppose it’s a specific model, but I couldn’t find a documentation on that.

For FOA there are three binaural decoders. Two are from measurement libraries, the third is a synthetic model. These three decoders are documented as you’d expect via the help page for FoaDecoderKernel. The direct links to each method are here:

1. FoaDecoderKernel.newSpherical
2. FoaDecoderKernel.newListen
3. FoaDecoderKernel.newCIPIC

1013 is the subjectID, in other words, the HRIR choice from a given library. In this case, the IRCAM Listen library. You’ll notice that we’ve provided a direct link to the LISTEN HRTF DATABASE on the help page. You can follow the various links available on the IRCAM page for more info.

Will more libraries be added? We’re intending to add the facility for users to “grow ur own” at some point in the future.

Hope this helps!
