Ambisonic Bidules

This is a Bidule plugin suite for Ambisonic processing. It is written mostly for testing amblib, an Ambisonic C++ library I have been working on. It is a work in progress and you are using it at your own risk.

It is based on three libraries: Kiss FFT for the fast convolution, mit_hrtf_lib which is a C library I have written that wraps the entire MIT Kemar HRTF compact set, and amblib.

The suite consists of the following Bidules:

  • Binauralizer(1 Order) – Decode 1st order BFormat to binaural outputs, with the option of selecting between normal and diffused HRTF sets. Supported sample rates: 44100, 48000, 88200, 96000 Hz.
  • Decoder(1/2/3 Order) – Decoder 1st, 2nd, and 3rd order BFormat to a list of preset speaker configurations.
  • Encoder(1/2/3 Order) – Encoder of mono signals into 1st, 2nd, and 3rd order Bformat.
  • Encoder with distance(1/2/3 Order) – As the Encoder, but adds cues for distance.
  • Processor(1/2 Order) – Rotate 1st and 2nd order BFormat around all three axes.
  • Zoomer(1 Order) – Zoom forward or backwards into BFormat soundfields.

Feedback is always appreciated.

    WINDOWS VERSION DOESN’T WORK IN ANY HOST

      NO NEED TO SHOUT… How about being more specific!? XP?Vista?7? 32/64 bit?

      Update: I just realised what your problem is… these are not VST/AU/DX plugins but Bidule ones which means they won’t work on any host other than Bidule. Had you made the effort to read the description, you would have known that instead of complaining.

    Thank you for these great tools…ambisonics working very well for me on OS X 10.6 and Bidule 0.971

  3. Hi Aristotel, I’m wondering if it’s possible to get hold of your Ambisonic to Binaural VST plugins for PC. Can’t find them here so I guess you removed them when you started using WordPress, hope you still have them stored somewhere.
    KVR still list them as available and I hope they’re right!

    All the best!

      Hi Johannes, sorry for the later reply. As that plugin is ancient and no longer supported, I don’t intend to put it on the new website. I am however emailing it to you. Just note that there is absolutely no documentation or general support I can give you on it.

      • I just received your e-mail, thank you! This is a small revolution, I can now actually hear the binaural and the B-format result while mixing, I’m not ‘blind’ anymore!

        Can I ask fot it too? I’m looking for a tool to convert 4-6-8 channels compositions to a stereo binaural for web streaming. I found your page searching on kvr. I’m trying some MAX objects and seeking a VST too.
        By the way, I love Bidule. I’ll try your suite. Unfortunaly the demo versio isn’t aavailable right now.
        Regards

    Hi Aristotel,
    as I found in a previous post these plugIns are not standard VST.
    I know that VST versions are older but I would like to give them a try.
    I hope to receive am email with an attachment. :)

    Thank you!

    Andrea
