MyBino v1.0.2 by X-Audio
Binaural monitoring plug-in

The X-Audio Team from the Ecole Polytechnique's Center for Applied Mathematics (CMAP) developped a free binaural monitoring plug-in. Born out of a collaboration with sound engineers of the Conservatoire National de Musique et de Danse de Paris (CNSMDP), this dynamic binaural engine allows you to mix and monitor up to 48 channels for each instance of the plugin, using the speaker setup of your choice.
This software uses HRTFs calculated with state-of-the-art interpolation techniques which allow a one degree precision. Various equalizations have been employed on those filters to seek the best compromise between timbre and externalization.

Extra Binaural Filters

Binaural rendering provides significant spectral coloration due to direction-dependent cues of the HRTFs and suffers from its current comparison to the reproduction of a stereophonic signal through headphones. Therefore, different methods have been employed to optimize the binaural processing and achieve a better balance between the externalization of sounds and the timbral coloration.
To reach that goal, the same filter set - taken form Ircam's LISTEN database - has undergone different processings. You can find here five different declinaisons, for now provided in the .xhead format.


The devices listed below work with MyBino via the Open Sound Control (OSC) protocol.
Hedrot (for "head rotation tracker") is a low-cost (less than 40 euros) and efficient open-source hardware/software solution for head tracking especially suitable for binaural rendering. Developed by Alexis Baskind together with sound engineers J.-M. Lyzwa and J.-C. Messonnier. This head-tracker has been adopted by the CNSMDP due to its great ergonomics, reliability and speed.
You can use the following smartphone apps as head-tracking devices. However their performances do not compete with hedrot's - in term of latency and calibration.
GyrOSC is a lightweight utility app that sends iPhone motion sensors over your local wireless network to any OSC capable host application. It transmits the built-in gyroscope's raw data provided by the Core Motion framework of your device. In order to work with MyBino, it has to send the gyroscope/gyro message.
oscHook periodically measures device sensor data and sends them in form of OSC messages. The orientation message only has to be sent to work with MyBino. Unfortunately, this app introduces a great latency which can't be reduced under 100ms - which is quite injurious to the binaural rendering.


This video demonstrates some features of MyBino :
  • monitor a multichannel mix;
  • use several instances to deal with a bed + objects approach (4'48);
  • receive the head-tracking data from hedrot (6'27);
  • use the standalone version (7'22).

The audio contents used in this demonstration are part of the Mixage Fou #8 soundbank. It gathers recordings realized by Rodolphe Alexis, Timo Klinge and Eckhard Kuchenbecker.

Some Audio Contents

An effective binaural rendering also depends on the content you use. The CNSMDP offers here some object-based audio contents. Their expertise in 3D audio recording methods permits to produce well-suited audio content for object-based audio mixing. You can find here the multichannel pieces and experience them through MyBino.
